Guide to Residential Landscape Development for Logan, UtahFotheringham, Michael Douglas 01 May 1978 (has links)
The ''Guide to Residential Landscape Development" has been written for the Logan City Planning Department as a supplement to the "City of Logan Guidelines for Development", a comprehensive planning tool adopted in 1976. The Guide is primarily intended to motivate Logan homeowners in designing, constructing and maintaining their residential properties by pointing out methods of design and construction that :
reduce costs of electricity, oil and natura l gas by reducing energy needs
Increase property values
maximize effective use of the property
improve the aesthetic qualities of the homesite
The Guide also serves as a prototype of the kind of consumer adyocqcy tool needed in many cities to help inform private citizens. of the vital role they can play in conserving energy and improving the natural and cultural environment in which they live.

The Study of Control Assessement for the Mechanism of Planned Participatory Judgement , and Strategies---------A case of yen-ye Award.Tsai, Ming-Wen 15 August 2007 (has links)
ABSTRACT
The effect of the urban landscape development influenced by the urban architecture movement through the means of participation during the evaluation process of the Yuan-Ye Building Landscape Award, sponsored by the Kaohsiung Judicious Creative Architecture Association is presented. The optimum resolutions of the public issues and policies through applying the mechanism of the participation of the public during the judging process have made the Award distinct from the others.
In the process, the Award has implemented the following steps to accomplish the objectives: applying the resource control from top down with a communication channel from bottom up, creating a new type of workgroup among the sponsors, professionals, and the public through participation of working with and learning from each other, forming of informal team to reduce miscommunications between the fields, conducting community meetings and revising questionnaire to modify participation strategy to seek urban space issues and to set the judging criteria, and, finally, offering realistic solutions to resolve the actual urban space issues.
To act on a theory as a study method, the Award, through the participants¡¦ comments of different roles to the situations and environments in the evaluation process while maintaining a comprehensive recordation, has developed a model of execution with suggested steps. In the process of action, with the complexity of the model and the growing number of participants and societies, the scale and the influenced range expanded gradually. In order to clear the situations, the report divided the system into two stages, the development stage and the fulfillment stage. Each stage has different steps with different events. The events such as the milestone of the event, the cooperation of the government, the reaction of the professionals and the expected result, all will interact on each other causing different effects to the whole operation. The feedback of the action can be extended to analysis the mechanism and interact of the model. The suggestion of improvement can be supplied to provide helpful information for the future reference.

Freshwater Wetland Creation in a Changing Urban Environment: Designing for Long-Term ViabilityBrown, Aaron Thomas Ryan 14 July 2017 (has links)
Urbanization and wetland mitigation are increasingly common in coastal watersheds with expanding populations. These mitigation wetlands are intended to offset the functional and structural losses experienced when natural systems are degraded or destroyed. In the Tampa Bay watershed, urbanization is both expanding into the upper reaches of the watershed and intensifying in previously-developed areas, resulting in the creations of hundreds of freshwater mitigation wetlands. This dissertation utilized an existing database of mitigation wetlands, publicly available data, and field surveys to investigate the relationship between constructed wetlands and their surroundings and also determine how design affects wetland condition over time. The overarching goals of this dissertation were to evaluate the geospatial distribution and areal extent of constructed freshwater mitigation wetlands in Hillsborough County and determine how they influence the landscape; evaluate design variables and environmental factors influencing constructed wetland trajectories; and determine how future changes to the landscape will likely affect constructed wetland systems.
The goals of Chapter 2 were to evaluate the relationship between mitigation wetland construction and total freshwater wetland area; determine if forested and non-forested wetlands are being impacted/mitigated at similar rates; determine if wetland mitigation is offsetting impacts from increased urbanization at the landscape scale. This study concluded that since 1985, permitted impacts of non-forested wetlands have occurred at a significantly greater annual rate than forested systems, despite their smaller regional footprint. Interestingly, this increased impact frequency, combined with mitigation ratios greater than 1:1 (mitigation to impact area), have helped decrease proportional difference in area between forested and non-forested wetlands in the region. Over the period of the study, mean LDI scores for drainage basins across watershed have increased, with those containing mitigation projects significantly increasing compared to those without. Changes in drainage basin LDI were significantly correlated to the number of mitigation projects per basin, total impact area, and total mitigation area. Upward shifts in drainage basin LDI categories have been documented in 25 of Hillsborough County’s 184 basins, however no significant connection to permittee-responsible freshwater wetlands was established. These results imply that current mitigation practices are failing to ameliorate increasing development intensity at the landscape scale.
The goals of Chapter 3 were to determine the current condition of created freshwater mitigation wetlands in Hillsborough County, Florida; determine if forested and non-forested wetlands maintain similar trajectories after release; and evaluate how design and changes in the landscape influence created wetland condition over time. Original wetland engineering plans and historical data were used to establish baseline conditions at the time of wetland “release” and track wetland changes over time. A chronosequence approach was utilized to determine wetland trajectories and analyze potential differences between forested and non-forested systems. This study found that surveyed freshwater wetlands had decreased in size from their intended area by a total of approximately 18%, but due to increased mitigation ratios, were likely still producing a net gain in total wetland area and meeting the goals of “no net loss”. On average, wetland condition (as determined by WRAP scores) decreased by 9% from the time of release to the time of survey. Few differences were observed between wetland types with the exception of canopy richness and wetland trajectory, although correlations between wetland condition and time were non-significant. From the regression optimization analyses, it appeared that wetland location (as measured in the design WRAP score) was one of the most important factors contributing to surveyed wetland condition.
In Chapter 4, future land use data was used to determine predicted anthropogenic pressure on these urban wetland systems and evaluate changes to the overall landscape. GIS based analyses on landscape development intensity (LDI) determined that significant changes are not expected at the landscape scale by the year 2025, however drainage basins that possess mitigation wetlands are anticipated to increase in development intensity. Predicted LDI scores for constructed freshwater wetlands is predicted to increase significantly, which could have detrimental impacts on wetland condition.
This dissertation highlights the significance of wetland design and location on wetland condition. From this research, it is apparent that consideration of site placement is the most important design variable for small (3 hectares or less) freshwater wetlands; and that understanding of future conditions may promote long-term success. Long-term studies such as this are valuable tools for understanding how specific ecosystems respond to changing landscapes and should be used to help shape policies that reflect these ecological advancements. Understanding the past and preparing for the future is the only way to foster restoration success.

Historický vývoj polní cestní sítě ve vybraných katastrálních územích / The historical development of unpaved road network in given cadastral territoryMÁCHA, Jiří January 2012 (has links)
The aim of the work was to assess and evaluate the historical development of road networks from the view of their projection in a comprehensive land adjustment. For this purpose, three cadastral areas, that represent a wide range of natural conditions, were chosen. Historical stages, in which the road network has been captured, were determined and studied in detail. To create an overview of the unpaved roads, evaluation criteria, by which individual areas were selected and compared in the chosen historical stages, were designed. On the basis of the results, the turning points of unpaved roads development were determined and their causes were described. The accomplished analysis of the road network in particular historical periods gives a clear overview in development of unpaved roads and arrangement of individual land lines. Historical image of unpaved road network, as an integrated complex, can be used only as inspirational material within the plan projection. This material has to be revised according to current legislation requirements, standards and wishes of landowners.

The Effects Of Urbanization On The Structure, Quality, And Diversity Of Cypress Plant Communities In Central FloridaKnickerbocker, Courtney 01 January 2009 (has links)
The integrity of wetland ecosystems is largely determined by hydrological functionality, degree of connectivity to like ecosystems, and permeability to external influence. Land use changes in upland areas adjacent to wetland ecosystems may influence hydrology and connectivity while introducing novel biotic and abiotic materials. There is an increasing trend toward the use of remote assessment techniques to determine the degree of impact of external influences on adjacent wetlands. Remote assessment and predictive capabilities are provided by indices such as the Landscape Development Intensity Index (LDI) (Brown and Vivas 2005) which may be beneficial in determining site condition, and which have the added benefit of providing a quantitative gradient of human impact. This study assessed the predictive ability of the LDI in cypress ecosystems, by testing its correlations with plant community metrics including an index of floral quality calculated using coefficients of conservatism (CC)(Cohen et al. 2004), plant species diversity, and fluctuation in community composition assessed by changes in the wetland status and native status of component plant species. LDI was also compared against an independent measure of disturbance which was used to construct an a priori disturbance gradient. Overall, diversity measures showed little correlation with any of the disturbance indices, while CC scores were significantly correlated. Models were constructed in an attempt to explain each of the variables of plant community response to development in the surrounding landscape. The length of time since the development of the land adjacent to the cypress domes was a predictor of plant community response only when included in models with other variables. LDI was the strongest predictor in all models except where increases in land use associated with hydrological changes helped predict or better predicted proportions of exotic and upland species.

Die Schwarzerden NordostdeutschlandsFischer-Zujkov, Ute 12 July 2001 (has links)
Schwarzerden und deren Kolluvien in der Uckermark als Forschungsobjekt werden als Archive zur Aufklärung der holozänen Landschaftsgeschichte und speziell der Bodengenese genutzt. Mit Hilfe eines speziellen interdisziplinären Methodenansatzes wurden Bodencatenen untersucht und im Hinblick auf ihren paläoökologischen Informationsgehalt interpretiert. Ergebnis sind differenzierte Aussagen zu Zuständen der holozänen Landschaftsentwicklung der Region Uckermark im Hinblick auf anthropogenen Einfluß, hydrologische Verhältnisse, Morphodynamik und Bodengenese sowie deren Ursachen- und Wirkungszusammenhänge. Voraussetzung für die Tschernosemgenese im Boreal und z.T. Atlantikum unter Laubmischwald sind die regionalen natürlichen Besonderheiten - der hohe Kalkgehalt des Substrates und die Klimaverhältnisse mit geringen Jahresniederschlägen. Seit dem Neolithikum bis zum Beginn des Mittelalters ist die Uckermark durch ein Vegetationsmosaik charakterisiert, das durch Offenlandbereiche innerhalb von Misch- und Laubmischwäldern gekennzeichnet ist und durch die ur- und frühgeschichtliche Siedlungsdynamik bestimmt wird. Der Landschaftswasserhaushalt in hydrologisch voneinander relativ unabhängigen Kleinsteinzugsgebieten des Jungmoränengebietes wird mit Beginn des Neolithikums sowohl durch die Siedlungsdynamik als auch den globalen Klimawandel beeinflußt und ist durch einen Wechsel von Trocken- und Feuchtphasen gekennzeichnet. Die Schwarzerdegenese und ihr Erhalt ist Ergebnis des Wandels paläoökologischer Zustände der holozänen Landschaftsgeschichte, die durch unterschiedlichen Verhältnisse der pedogenetischen Prozesse Tschernosemierung und Lessivierung auf der Grundlage des unterschiedlichen Zusammenwirkens der natürlichen und anthropogenen Faktoren bestimmt werden. / Phaeozems and their colluvia in the Uckermark were used as archives for the reconstruction of the holocene landscape history and particularly the pedogenesis. Soil catenas were examined and their palaeoecological information interpreted with the help of a special interdisciplinary combination of methods. Results are differentiated conclusions to stages of the holocene landscape development of the region Uckermark regarding anthropogenic influence, hydrologic conditions, morphodynamics and pedogenesis as well as the relations between them. The genesis of chernozems in the Boreal and partly the Atlantic period under leaves mixed woodland was caused by the special regional environmental conditions - the high content of carbonates in the substrate and the climate conditions with low yearly precipitation. Since the neolithic period up to the beginning of the Middle Ages the Uckermark is characterized by a vegetation mosaic consisting of leaves mixed woodlands and open land areas. The vegetation mosaic is determined by pre- and earlyhistorical settlement dynamics. With the beginning of the neolithic period the landscape water regime in mostly hydrologically independent small catchment areas in the young morain area is influenced by both, the settlement dynamics and the global climatic change. The water regime is characterized by an alternation of dry and humid phases. The genesis of chernozems and its conservation in form of phaeozems is the result of the change of palaeoecological stages of the holocene landscape history. The different conditions of palaeoenvironment, caused by various kinds of interaction between the natural and anthropogenic factors, determined the differences of the relation between the pedogenetic processes, the genesis of chernozems and their lessivation.

Investigating Sand Dune Location, Orientation and Geomorphometry Through GEOBIA-Based Mapping: A Case Study in Northern Sweden / En undersökning av rumslig förekomst, orientering och morfometri hos fossila sanddyner genom GEOBIA-baserad kartläggning: en fallstudie i norra SverigeStammler, Melanie January 2020 (has links)
Climate change has repeatedly been framed as the defining issue of the Anthropocene and with the Arctic changing at unpreceded speed need is high for a profound understanding of the Northern Swedish landscape. Northern Swedish aeolian sand dunes have been impacted by climatic changes throughout time. Their location, orientation and geomorphometry can therefore be used to explore past wind patterns and dune activity. By systematically and spatially mapping the dunes, patterns in location can be illustrated, dune orientations investigated, the dunes’ geomorphometry characterised and sediment sources determined. Based on this knowledge, insight in landscape development along with a better understanding of long-term landscape (in)stability in Northern Sweden can be gained. This M. Sc. thesis sets out to summarize useful concepts to understand the formation of Northern Swedish aeolian sand dunes and to derive its implications for understanding landscape development. Based thereon, it deduces the strong need to systematically and spatially analyse aeolian sand dunes in Northern Sweden. The use of geographic object-based image analysis (GEOBIA) allows for the detection of potential dune locations over a large area and provides defined and reproducible mapping boundaries. Polygons are created by segmenting a residual-relief separated digital elevation model (DEM) as well as slope and curvature data. The multi-resolution segmentation provides best results with a scale parameter of 15 and a homogeneity criterion of 0.1 for the shape criterion, as well as 0.5 for the compactness criterion. A rule-based classification with empirically derived parameters accepts on average 2.5 % of the segmented image objects as potential dune sites. Subsequent expert-decision confirms on average 25 % of the classified image objects as identified dune locations. The rule-based classification provides best results when targeting a smaller area as this allows for less variability within the dune characteristics. The investigation of expert-accepted dune locations confirms a prevalence of parabolic dune forms, reveals the coexistence of simple dunes with large coalesced systems, exemplifies variation in dune orientation and highlights that the majority of dunes are supplied by glaciofluvial deposits. By mapping Northern Swedish aeolian sand dunes and investigating their meaning for landscape development, this thesis furthermore contributes to closing the gap identified for research on Northern Swedish aeolian sand dunes. / Den första associationen till sanddyner är säkert Sahara snarare än norra Sverige. Ändå är dessa fossila sanddyner också mycket relevanta och intressanta att studera. De kan analyseras i samband med det omgivande landskapet och dess orientering. Dessa egenskaper hjälper till att identifiera mönster i landskapsutveckling. Detta och på grund av dynarnas relativt gamla ålder kan slutsatser om landskapets (in)stabilitet på geologiska tidsskalor dras. Detta är mycket användbart eftersom det kan ge insikter om hur klimatet såg ut under tiden som sanddynerna bildades - perioder där människor ännu inte har bevittnat klimatet. Kunskap som till exempel hur klimatet som rådde för länge sedan såg ut kan användas bland annat för att uppskatta hur landskapet kommer förändras i framtiden till följd av klimatförändringar. Trots dessa användbara egenskaper hos sanddynerna har lite forskning gjorts hittills. Det här examensarbet försöker motverka detta kunskapsgap och kartlägger sanddyner i norra Sverige med hjälp av geografisk objektbaserad bildanalys (geographic object-based image analysis, GEOBIA). Det innebär att bildmaterial och digitala höjdmodeller frigjorda från vegetation automatiskt analyseras med hjälp av algoritmer. Fokus här är inte på att analysera enskilda pixlar. Snarare grupperas pixlar med liknande egenskaper så som lutning (slope), krökning (curvature) och spektralegenskaper. Dessa blir sedan grunden för analysen. Möjliga sanddyner upptäcks semi-automatiskt så att deras position och orientering sedan kan analyseras. Den kunskap som erhållits på detta sätt utgör grunden för vidare forskning. Ett annat mål är att bidra till en djupare förståelse kring landskapsutvecklingen i norra Sverige. Det är viktigt att komma ihåg att detta är ett område som särskilt påverkas av klimatförändringar. En ökad kunskap om landskapets tidigare klimatrespons kan därmed bidra till att förutsäga framtiden för denna region. Förutom att öka kunskapen kring sanddyner i norra Sverige hjälper det här mastersarbetet även till att utvidga användningen av GEOBIA inom geomorfologiska studier.
