The purpose of this study is to provide a description of the repercussions of hydro-dam development upon forestry in southeastern British Columbia. This study develops a systems viewpoint, where selected indicators - timber supply, access and transportation, forest land value, and reservoir clearing - are examined to help place land allocation decisions within a comprehensive framework. First, a timber supply model is developed, in which forest land withdrawal to hydro-dams is scrutinized. The model is then expanded to account for timber supply and demand relationships. Findings reveal that approximately 50,000 hectares of better than average sites were withdrawn from forest land, accounting for a reduction in timber supply of approximately 180,000 cubic meters annually. Second, changes in accessibility and transportation patterns due to hydro-dam projects are identified in terms of timber supply disruption, and strategies followed to re-establish forestry. Mica and Revelstoke dams are examined to show the importance of allocating economic resources to forestry for the maintenance of the activity. Third, forest land is evaluated in following the four methodological steps: (1) outline of a benefit-cost analysis framework, (2) definition of a general approach to evaluation, (3) description of B.C. Hydro's assessment, and (4) recommendations for improvement. The case of the Revelstoke Dam is examined, and it is concluded that resource development scenarios must take into consideration timber supply and demand factors. Fourth, reservoir clearing is described to outline an important aspect of short-term impact, and to express the way by which the Forest Service, B.C. Hydro and forest companies co-ordinated their efforts during this transition phase. The study concludes by suggesting that the impacts may be alleviated by initiating intensive forest management in areas affected by hydro-dam projects. The design of an effective system of timber allocation may also permit maintenance, and possible improvement, of accessibility and transportation patterns. However, the success of these actions depends upon the availability of sufficient funding. Finally, within a broader perspective, it is recommended that integrated resource management, as a control mechanism for land allocation and management, be adopted. / Science, Faculty of / Resources, Environment and Sustainability (IRES), Institute for / Graduate

This dissertation explores the reasons behind the impasse over the implementation of the LHWP II between communities affected by the construction of the Polihali Dam in Mokhotlong District in Lesotho and the Lesotho Highlands Development Authority. This conflict which has threatened the implementation of the project has been looked at in terms of disagreements over the compensation package for the displacement and losses. Using an actor-oriented approach, the contention was that explanations of the impasse should go further than the simplistic explanations of compensation and non-compensation, but should focus on the dynamics of interaction between different actors involved in the Polihali case. The investigation of the particular context of the Phase II implementation reveals a complex arena; where different actors are pursuing different agendas and using the power at their disposal to achieve these agendas eventually struggled to find common ground. It also reveals a need to incorporate the perspective of these actors into any explanation of the impasse. Using this approach, the investigation identifies several factors of which the compensation package is only a part which contributed to the conflict. Chief among these factors was how the LHDA handled the situation. Dislocations are traumatic experiences and require that those affected should be fully involved in decisions that affect their situation, yet the LHDA engagement failed on the basic participation principles. The authority modelled its approach to community engagement on tokenism and allowed people’s consultation, but disregarded their inputs in the final decision making. This resulted in a skewed understanding of society and losses resulting from dam construction, which caused tensions between the authority and the communities. Therefore, this dissertation concludes that; while compensation was certainly a significant aspect in the impasse, the gap between what was compensated and expectations reflects a general lack of knowledge of society and the social dynamics guiding life in these societies, which arose from the failure of the approach adopted by the LHDA. The study therefore advocates a search for a new rural development narrative that will move away from assumption about the viability of small family farms. It also reveals a need to incorporate people affected by large dam development in all aspects of the project that affect their lives. / Dissertation(MSocSci (Development Studies))--University of Pretoria 2020. / Anthropology and Archaeology / MSocSci (Development Studies) / Unrestricted

Thesis advisor: Noah Snyder / The dynamics of river suspended sediment, derived from soil erosion, is critical for understanding floodplain and coastal wetland evolution, as well as reservoir sedimentation. Although the U.S. Geological Survey (USGS) has collected > 105 suspended sediment concentration (SSC) samples, data availability is often sparse or altogether lacking for large river transects. Landsat derived SSC measurements have proven accurate enough to supplement USGS datasets, allowing unprecedented spatial analysis of SSC trends throughout large river systems (Dethier et al. 2020). Here, I build on this approach by applying it to higher spatial and temporal resolution datasets. I have derived suspended sediment concentrations from the Sentinel-2 satellite sensor through a cluster and regression approach. To increase the number of training samples, I constructed SSC-discharge rating curves for all in-situ USGS stations. This has constrained the uncertainty of Sentinel-2 derived SSC to less than a factor of two, which has proven adequate for large rivers. In combination with the Landsat record, this allows for a multi-decadal analysis of sediment transport dynamics across multi-dammed systems. This study applies these methods to the Chattahoochee River in Georgia and Alabama, USA. Using observations from 1984 to 2022, there exists pronounced decreases in SSC downstream of dams along the river, with downstream reaches never regaining the same values as upstream observations. Also evident is a decreasing trend in SSC temporally, which could be indicative of changing land-use practices.

A project report submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science in Engineering. / The research report summarises the theory of consolidation, for both linear infinitesimal strain, and for non-linear finite strain. The non-linear finite strain theory isadopted in a computer program to model the building of a tailings dam by thin layers. This program provides the pore water pressure profile over the depth of the deposit, as well as the settlement of the deposit. Making use of the program and the consolidation properties of five mining residues and two industrial residues, the build up of excess pore water pressures is modelled for different rates of deposition of the waste products. These results are used in determining how the rate of deposition affects the stability of the outer slope of a tailings dam. Also, the difference in the stored volume in a dam is investigated, based on different drainage condltions and rates of deposition. / Andrew Chakane 2018
