The purpose of this thesis is twofold: first, to review the literature on economic impact analysis in general, and port-economic impact literature in particular; and second, to use this background to undertake an economic impact assessment. The case study for this thesis is Fraser Port, which is located along the lower reaches of the Fraser River in British Columbia's Lower Mainland metropolitan region. The port is administered by the Fraser River Harbour Commission. This thesis is about production, people, and the economic significance of Fraser Port. This thesis is not an analysis of economic impact theory, but a review and application of port impact identification techniques. All data and impacts presented relate to 1992. Ports perform a necessary function in a nation's trading system by providing a transshipment connection between land and water modes of transport. As such, the port is strategically connected to the production of the many goods passing through its facilities. For this thesis, the impact of the various commodities passing through the port is termed port-associated. The port also manifests its presence through its daily operations and generates numerous employment opportunities both within and beyond the confines of the waterfront. The economic impact driven by this activity is termed port-industry and most closely reflects the impact of the working waterfront. To complete the impact assessment of the port-industry category, a survey was undertaken to collect sales revenue and employment information. This data was then aggregated into specific industry sectors and a total economic impact was estimated using appropriate economic multipliers. The result was a picture of direct, indirect, and induced activity resulting from the daily operations of the port. The port-associated category was assessed in a slightly different manner. The value of each cargo was determined and, where appropriate, was assessed for the economic activity related to its production. This activity is not generated by the port, but is associated with Fraser Port through the use of its transshipment services. The results of the assessment reveal that the port-industry category generates approximately one quarter of a billion dollars of provincial gross domestic product (GDP). This led to a total GDP impact across Canada of close to $275 million. Employment amounted to about 2,113 full-time equivalent positions in B.C. and nearly 3,400 across Canada. In 1992, the total value of import and export cargo passing through Fraser Port was approximately $6.1 billion, $3.8 billion of which was international imports. The remainder, $2.3 billion, was made up of domestic outbound and inbound cargoes, and international exports. It is important to recognize that these two categories of port activity are measures of different effects. The results of the port-industry and port-associated categories should not be added to produce a total Fraser Port impact. Adhering to this recommendation will ensure that the figures, and thus Fraser Port, will not be misrepresented to the public. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

In the canyon where the Fraser River flows through the Cascade mountains, migrating salmon supported a large, dense native population. By 1850 the Hudson’s Bay Company had several forts on other parts of the Fraser River and its tributaries but found the canyon itself inaccessible. Prior to the gold rush, whites rarely ventured there. Discoveries of gold in Fraser River in 1856 drew the attention of outsiders and a rush of miners, and led eventually to permanent white settlement on mainland British Columbia. Contrary to much historiography, these were not foregone results. Instead, the gold rush was a complex process of negotiation and conflict among competing groups as they sought to profit from gold discoveries. The Hudson’s Bay Company sought to gain and retain control of the resource by incorporating it into its trade and by excluding outsiders. But miners arrived by the thousands, and the Company was forced to try to regulate miners’ access to the resource. However, as a group, miners were cohesive and self-reliant; they had little need for outside intervention. The Hudson’s Bay Company was unable to regulate them while pursuing its own ideas of profit. The British government subsequently revoked the Hudson Bay Company’s trade license, and proclaimed British Columbia a colony. In efforts to impose its own ideals of order on the gold fields, the government introduced a new colonial administration which, following a chain of command extending from London through Victoria to the Fraser, sought to organize the population in the spaces of the Fraser Canyon. Government authority was reinforced by the legal system’s flexible responses to the diverse population’s activities it deemed illegal. By studying the interactions of natives, miners, traders, administrators, and the legal system, I have attempted to untangle the ways in which white men negotiated their particular racist and masculinist ideals and sought to impose them in the spaces of the Fraser Canyon. / Arts, Faculty of / Geography, Department of / Graduate

Wood debris has been a natural component of the Fraser River system for centuries. However, with the development and expansion of a diverse forest industry in British Columbia, the volume of waterborne logging wastes being discarded into the river has gradually increased to the point where logging slash, uncontrolled sawlogs, trimmed log ends and dislodged bark now present a serious problem to the users of the Lower Fraser and its shorelands. Where water pollution can be defined as any residual discharge into a watercourse which causes both a deterioration in the quality of the receiving waters and some form of related social costs, sawlogs and other types of wood debris present a rather unique example of a pollutant to the Lower Fraser River. From this perspective, the available literature on pollution control provides an appropriate methodology for defining and analyzing the issues and problems associated with the presence of this material in the waterway. In 1972, uncontrolled sawlogs accounted for 9.2 million cubic feet of wood debris or roughly 80 per cent of the total debris load in the river. These logs were responsible for approximately 4.5 million dollars in costs to fishermen, pleasure boat owners, harbour authorities, and private logging companies. While it is realized that there are substantial additional costs related to the environmental impacts of sawlog debris, more studies are needed to determine the significance of these impacts on / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

The purpose of this study is to examine the social opportunity cost of preserving specified recreation sites along the lower Fraser River. In achieving this purpose it does the following: 1. it examines the institutional arrangements whereby land is allocated to specific uses, 2. it identifies the potential recreation sites for possible preservation, 3. it assesses the nature and extent of the conflict between recreation sites and existing and potential industrial shoreland use, 4. it develops an analytic framework for examining the social opportunity cost of preserving recreation sites, 5. it applies the framework to determine the benefits which the region might forgo if it were to preserve the recreation sites identified. An examination of the institutional setting found that private markets alone may not provide recreation facilities in the lower Fraser in accordance with society's willingness to pay for them. Public institutions have evolved to regulate the market, however, and an analysis of the social opportunity cost of preserving recreation sites is made in order to assist decision makers in future shoreland allocations. For this analysis to be meaningful it was necessary to identify specific recreation sites, and to determine the nature and extent of the conflict between these and industrial use. Thirty-two major recreation sites were identified. About two-thirds of these were found to conflict with potential industrial needs for shoreland designated industrial by the Regional Plan, and with log storage activities of the forest industry. Ideally a technique for allocating shoreland to recreational or industrial uses should be based on an assessment of the benefits and costs of alternative land uses. However, an opportunity cost approach is all that is practicable at this time because of the difficulties associated with evaluating present and future recreation demands. A qualitative approach to the evaluation was devised because past attempts to measure social opportunity cost were not appropriate in this situation where concern was primarily with demand far into the future. The analysis focussed on the rental value differences between industrial use of shoreland and upland, the supply and demand for industrial shoreland, and the cost of log storage alternatives. The analysis produced four main findings. First, most firms do not attach a significantly higher rental value to shoreland than to upland sites. Second, the supply of waterway access is much greater than anticipated industrial demand, and the opportunity cost of preserving land with recreation potential is zero in the short run. Third, the study area has sufficient land designated industrial that a small reduction for the preservation of recreation sites will net affect the land market. Four, seasonal storage leases and bundle booming can be implemented to free recreation sites of stored logs without incurring a net opportunity cost. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

The primary objective of this study was to evaluate quantitatively the effects of a mixture of agricultural and non-agricultural land use practices on the chemical characteristics of the Salmon River, near Fort Langley, B.C. Present land use and geomorphic unit maps were used to determine appropriate stream sampling sites which would give an indication of the combined and separate effects of land use and geologic materials on water quality. Chemical characteristics of the Salmon River and its tributaries were monitored over a 10 month period from May 1974 until April 1975. Eighteen chemical variables were analyzed in the laboratory using Standard Methods and 5 were monitored in the field. The in situ parameters included pH, temperature, oxidation-reduction potential, specific conductance and dissolved oxygen levels. Also monitored were 7 trace metals, Cr, Cu, Fe, Mn, Ni, Pb and Zn. Atmospheric precipitation collectors were installed at the end of June 1974 and precipitation samples collected monthly from July 1974 until April 1975. Eighteen separate chemical variables were monitored at these sites using standard methods. Stream bed sediment grab samples were taken in May and again in July 1974. These_ samples were analyzed for total elemental composition as well as total nitrogen, total carbon, total sulfur, total cation exchange capacity, exchangeable cations (Ca, Mg, Na, K) and pH. The major geologic materials in the watershed were sampled in 6 sites located in undisturbed and cultivated areas on marine, glacial outwash, and alluvial materials. The monitoring of some selected chemical characteristics of the Salmon River revealed in general the mean values of pH, specific conductivity, temperature, total alkalinity, total HC03 alkalinity, total hardness (CaCO₃ equivalent), total dissolved solids, total Kjeldahl N, organic C, NO₃ -N, CI, Na, and K were consistently higher at low streamflows than at high (>750cfs) streamflows. Oxidation reduction potential and dissolved oxygen mean values were consistently higher at high flows than at low flows. The other variables measured remained relatively constant on average across all levels of streamflow. There was, however, considerable variation at specific point samples. Data derived from collection of atmospheric precipitation indicated a significant input of many chemical factors to the watershed. Bed sediment and soils chemical characteristics give a general indication of the amounts and distribution of the various chemicals potentially available for contribution to stream waters. Analysis of the results obtained in comparison with water quality standard acceptable levels revealed water quality problems with pH, temperature, phosphorus, iron, copper, and manganese. Significant statistical correlation exists between water quality variables and glaciomarine, marine and beach overlying marine or glaciomarine materials; glacial outwash materials; agricultural field crops; low density residential areas; and schools. In order to identify specific point and non-point sources more detailed information is needed on groundwater characteristics and the streamflow characteristics of tributary streams. Some general management alternatives are recommended bearing in mind that each site must be evaluated on its own merits and specific suggestions made on-site. / Land and Food Systems, Faculty of / Graduate

The Fraser Estuary was investigated five times under varying flow regimes. The surface distribution of dissolved manganese consistently exhibited a maximum value at a salinity ranging from 4 to 12 ppt. Experimental results and field data suggest this peak does not result from the desorption nor dissolution of riverborne suspended particulate manganese. The excess metal is derived from the estuarine bottom sediments. Desorption or dissolution of manganese from the estuarine bottom sediments resuspended due to the advancing salt wedge enhances the dissolved manganese concentration in the bottom waters, especially in the toe of the salt wedge. This manganese enrichment may also be influenced to a lesser extent by the concurrent release of some interstitial water with enriched dissolved manganese concentrations due to the in situ reduction of amorphous manganese oxides. The subsequent entrainment and mixing of water from the toe of the salt wedge into the outflowing river water causes a downstream increase in the dissolved manganese content, and eventually determines the peak manganese concentration and salinity. Further downstream mixing with saline waters having relatively low manganese levels causes surface concentrations to decrease. Thus, the dissolved manganese distribution can be explained in terms of two conservative dilution curves which intersect at the manganese peak. The dissolved oxygen generally behaves conservatively in both the surface and bottom waters of the Fraser Estuary. The removal of alkalinity may occur at low salinity, however, alkalinity exhibits conservative behaviour through most of the salinity range. The surface distribution of pH can be replicated theoretically only when mixing in the surface is considered as a two step process. The alkalinity behaves conservatively in the surface waters of the Strait of Georgia. The pH and dissolved oxygen display seasonal variations related to primary productivity and mixing processes. The distribution of dissolved manganese in surface waters of the Strait of Georgia is determined mainly by the dilution of Fraser River water. Bottom waters have enhanced dissolved manganese concentrations due to reductive remobi1ization of manganese from the sediments. Concentrations of dissolved manganese at mid-depths are determined by seasonal variations in the stability of the water column. Depth profiles of suspended particulate manganese indicate increasing concentrations with depth. This may result from the oxidative precipitation of manganese and/or the resuspension of bottom sediments. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

Having a perception about the water quality of a river can determine its usefulness, as a supply of water and also for recreational purposes. If it is determined that the river water is in a poor state, then it can have an impact on the community’s health, the economy of a settlement, as well as the natural environment along the course of the river. The main aim of this research is to determine what the community of Hartenbos’ opinion is concerning the water quality of the Hartenbos River and what is the true state of the water quality of the Hartenbos River? This could seem as a positive or negative influence on sustainable development and environmental conservation. The town of Hartenbos and the Hartenbos River is situated on the Southern Cape Coast in the Western Cape Province. A questionnaire survey, employing a stratified random sample method, is conducted during the month of April 2005. The Department of Water Affairs and Forestry (Belville) obtain water quality variables from nine sampling points. The results are analysed for a ten-year period (1994-2004) by STATKON, an independent statistical consultant based at the University of Johannesburg (Kingsway Campus). Analysis methods include a repeated measure of variance (ANOVA) and the Wilcoxon Signed Rank Test. These results are compared with the South African Water Quality Guidelines for domestic, recreational and agricultural (irrigation and livestock watering) use. The results show that the state of the water quality of the Hartenbos River is in a good condition and thus acceptable within the modern urban environment. The researched population mainly disagrees with this statement. According to the opinion of the research population, the water quality is in a poor condition, thus unacceptable within the modern urban environment. According to them, human activities within the river and its catchment and poor management are to be blamed. Although the opinion of the research population is genuine and rightful, the opinion is overruled by the water quality results. Economic development such as tourism and residential development will improve the local economy. The local community’s opinion can alter new developments because of their perception regarding the water quality of the Hartenbos River. How the local community’s opinion compare with actual scientific information, will determine its value or correctness and thus, the positive or negative impact on economic development. The state of water quality and the ecosystem must be maintained. An appropriate environmental management plan and enforcement of existing laws will ensure harmony between any existing or future economic development and the conservation of the Hartenbos River. The Hartenbos River with all its functional and aesthetic properties has to be conserved for generations to come. / Dr. P.J. Wolfaardt

Against the background of a rapidly collapsing socialist empire in Eastern Europe and the former Soviet Union, socialist China has since the late 1970s consciously endeavored to develop a "socialist market economy with Chinese characteristics." This thesis assesses the process of economic and spatial transformation in the Zhujiang (Pearl River) Delta, one of the fastest growing economic regions in China. The purposes are to identify the general pattern of economic and spatial changes, to determine the key forces responsible for such changes, and to explore the theoretical implications of these changes in the broader context of interpretation about the operating mechanism of regional development. The overall objective is to understand how a regional economy under socialism is transformed after the intrusion of global market forces. My analyses of regional data and indepth case studies reveal that the Zhujiang Delta has since 1979 moved away from the previous impasse of involutionary growth or growth without development and entered a new era of real transformative development in which dramatic growth has occurred not only in agricultural and industrial output but also in labour productivity, per capita income, and employment. The take-off of the delta's regional economy has owed little to the expansion of state-run modern manufacturing, but has been fueled primarily by numerous small-scale, labour-intensive, and rural-base industries. The spatial outcome of this rural industrialization has been a rapid urbanization of the countryside, especially of the area adjacent to and between major metropolitan centres. There has been no increasing concentration of population in large cities as the conventional wisdom of urban transition might have predicted. Regional development in the Zhujiang Delta during the 1980s was not an outcome of any active state involvement. It was instead a result of relaxed control by the socialist central state over the delta's regional economy. Local governments, along with the collective and private sectors, are found to be the chief agents responsible for the transformation of the peasant economy and the development of the transport infrastructure. The penetration of global market forces via Hong Kong into the Zhujiang Delta has significantly facilitated the process of economic, spatial, and social transformation. This study of the operating mechanism of regional development in the Zhujiang Delta presents a dialectical model of local-global interaction to combat the two prevailing schools of exogenism and endogenism. It also suggests that previous theories on Chinese regional development, which assumed a strong socialist central state monopolizing local economic affairs, might need fundamental modifications. For the Zhujiang Delta, the development of which is still in the early take-off stage, the establishment of a modern transport infrastructure has shown remarkable effects, leading to rather than following the growth of the delta's economy. Finally, the relocation of transnational capital and manufacturing production from Hong Kong to the Zhujiang Delta has not displayed a spatial tendency of high concentration in the primate city as the conventional theory of globalization would suggest. Non-economic factors such as historical, cultural, and social linkages between investors and their target regions are found to have played a major role which should not be overlooked in understanding the mechanism and spatial patterns of the internationalization of production. / Arts, Faculty of / Geography, Department of / Graduate

Pitt River, 30 km inland from. Vancouver, British Columbia at the southern margin of the Coast Mountains, links Fraser River estuary and Pitt Lake. Salt water seldom extends to within 10 km of Fraser - Pitt confluence; nevertheless, tides modulate Fraser flow and cause Pitt River to fluctuate 2 m and Pitt Lake as much as 1.2 m. There is an upstream movement of sediment in Pitt River from Fraser River, evidenced by identical mineralogy of Pitt River and Fraser River sediments, a decrease in grain size from the Fraser to Pitt Lake, and a predominance of flood-oriented bedforms in the river channel. A delta of 12 km2 area has accumulated at the lower (draining) end of the lake. The purposes of the study were to: (1) examine aspects of the hydrodynamics of Pitt River and Pitt Lake as a tidal system; (2) evaluate the effect of bidirectional flow on river and delta morphology; (3) determine processes of sediment movement in the river and of-sediment dispersal on the delta; and (4) estimate present sedimentation rate on the delta. Water Survey of Canada stage data from 3 locations in the system, used in conjunction with velocity measurements (profiles and tethered meter), revealed large seasonal and tidal variations in discharge. Calculations indicate that flood basal shear stress peaks early in the flow, whereas ebb currents have a lower basal, shear stress which peaks late in the flow. Thus, sediment moves farther forward on a flood flow than it moves back on the succeeding ebb. Studies of the river channel using hydrographic charts revealed regular meanders (^M = 6100. m) and evenly spaced riffles and pools which are scaled to the strongest flow (winter flood current, Qe). Meander point bars are accreting on the "upstream" side indicating deposition by the flood-oriented flow. The three dimensional geometry of the large-scale bedforms which cover the sandy thalweg of both river and delta channel was determined by echo sounding and side-scan sonar. Three distinct sizes (height/spacing = 0.8 m/10-15m; 1.5m/25-30 m; 3 m/50-60 m) of large-scale bedforms (sand waves) were found; their linear-relationship of height vs. spacing (XD) on log-log plot suggests a common genesis. The size appears to be related to channel geometry, not to depth of flow. Largest forms are found in reaches which shallow in the direction of water movement and smallest forms occur on relatively flat topography. The following tentative relationship is suggested for sandy meandering rivers: ^M/^B = Qe. Pitt delta morphology was studied with aerial photos and depth soundings. Its shape is considered an excellent example of sediment diffusion and deposition from a simple jet into a low energy lacustrine environment. Analysis of 190 sediment samples from river, delta, and lake bottom shows the sediment to be polymodal. Graphical partitioning of the cumulative probability plots reveals that sediments are composed of up to 4 log-normal distributions. Each distribution is interpreted as a population related to a process of sediment transport. Five subenvironments in the Pitt system are characterized by unique combinations . of these "process" populations. Cores in the delta topsets and lake bottom sediments reveal silt and clay rhythmites, interpreted as varves. The coarse layers are deposited during winter when discharge of Fraser River is low and tidally induced discharge in Pitt system is high. The fine layers are deposited during spring run-off when additional fines are added to the lake from the Pitt basin. 137Cs dating of sediments shows that as much as 1.8 cm/yr are accumulating in the active portions of the delta with an estimated 150 +/- 20 X 103 tonnes deposited annually. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The quality of surface runoff in an urbanized watershed was studied in order to determine the effects of land use and hydrologic conditions. Sampling sites were established so as to be representative of varying land uses and were monitored over a six month period so as to reflect changing flow conditions . Twelve sites, sampled weekly, were established in the Brunette River Basin, an urban watershed located in the Lower Mainland of British Columbia. Water samples, taken at each site, were analyzed for nineteen water quality parameters. Information relating to the hydrology and land uses of the basin was taken from established sources. Multiple regression and analysis of variance techniques were used to relate the land use and hydrology of the basin to the water quality. Total phosphorus, suspended solids and turbity concentrations were directly related to the percentage open space. Specific conductance and the nitrogen compounds were directly related to the percentage residential land. Eight parameters, but particularly turbidity and suspended solids, were dependent on stream discharge. The sensitivity of the data varied from site to site depending on the characteristics of the contributing areas. Discussion was directed toward the spatial and temporal nature of the data, the variance in the data, and the associated problems of scale. / Arts, Faculty of / Geography, Department of / Graduate
