Social analysis of a watershed restoration project in central IdahoCottingham, Sara Worth 16 November 2010 (has links)
The purpose of this study is to explore meanings of success in watershed
restoration projects. Though restoration has both inherent ecological and social
components, the social elements often remain unexamined. Using the Mores Creek
Watershed Floodplain Restoration Project in Central Idaho as a case study, this study first
reviews existing literature pertaining to watershed restoration, landscape ecology, and
ecosystem services, and then uses stakeholder interviews to analyze restoration goals,
perceptions of success and failure, and perceived benefits and burdens of the restored
watershed. Finally, the study concludes with recommendations for maximizing success in
watershed restoration projects. / text

Effects of Spatially Distributed Stream Power on Check Dam Function in Small Upland Watersheds: a Case Study of the Upper Laja Watershed, Guanajuato, MexicoHerzfeld, Zachary Andrew 20 January 2017 (has links)
Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through constructing check dams in well-selected locations. This practice has been used throughout the upland subwatersheds within the Upper Laja River watershed in Guanajuato, México. The present study employed Wolman pebble counts to systematically assess the effectiveness of 21 check dams located near the city of San Miguel de Allende. Particle size distributions taken directly downstream and upstream of each check dam were differentiated, aggregated and compared--with the difference between median particle size of downstream and upstream distributions defined as DsD50-UsD50. Several subwatershed attributes were calculated in a GIS for comparison to DsD50-UsD50 values. Results indicate that, on aggregate, the check dams studied were moderately successful at retaining sediment that becomes entrained in concentrated flow (DsD50-UsD50 = 15.4 mm; p < 0.001). Individually, 18 of the 21 check dams surveyed had statistically significant differences between DsD50 and UsD50 (p < 0.05). The subwatershed variables of local channel slope (r = 0.55), mean subwatershed slope (r = 0.46), subwatershed area (r = 0.59), distance from channel head (r = 0.54), percent canopy cover (r = 0.46), Qmed (r = 0.46), total stream power (r = 0.58), and change in total stream power (r = -0.45) were found to be statistically significant when correlated with DsD50-UsD50 values (p < 0.05). Change in total stream power was used to classify stream reaches as either erosion or deposition-dominated. When compared, the DsD50-UsD50 values from check dams located in erosion and deposition-dominated reaches are statistically different (p < 0.05); higher performing check dams were predominantly found in deposition-dominated reaches. The results of this study suggest that spatially distributed stream power can be used as a variable for making decisions about future check dam locations. In particular, check dams are more likely to be effective if they are located within deposition-dominated areas (negative change in total stream power) and in areas of decreasing change in total stream power. In general, this study's findings also support locating check dams in second order streams.

Mapping riparian vegetation functions using remote sensing and terrain analysisLymburner, Leo January 2005 (has links)
Land use practices over the last 200 years have dramatically altered the distribution and amount of riparian vegetation throughout many catchments in Australia. This has lead to a number of negative impacts including a decrease in water quality, an increase in sediment transport and a decrease in the quality of terrestrial and aquatic habitats. The task of restoring the functions of riparian zones is an enormous one and requires spatial and temporal prioritisation. An analysis of the existing and historical functions of riparian zones and their spatial distribution is a major aid to this process and will enable efficient use of remediation resources. The approach developed in this thesis combines remote sensing, field measurement and terrain analysis to describe the distribution of five riparian zone functions: sediment trapping, bank stabilization, denitrification, stream shading and large woody debris production throughout a large semi-arid catchment in central Queensland.

Restoring Our Urban Streams: A Study Plan for Restoring/Rehabilitating Stroubles Creek in Blacksburg, VirginiaZhou, Daquan 01 June 2004 (has links)
As the Americans have become more aware of the impact to the environment from the human induced disturbances which includes physical, chemical and biological disturbances to the degradation of streams and rivers, many studies and experiments have been done in an attempt to restore streams and rivers to more natural conditions. At the same time, success in public education and community involvement has encouraged grass-root movements that engage people in stream restoration efforts.
Stroubles Creek is a freshwater stream located in Blacksburg, Virginia. The creek has experienced considerable disturbance due to land use changes over the past 100 years. The Stroubles Creek Water Initiative (SCWI), originated by the Virginia Water Resources Research Center at Virginia Tech, has been monitoring the creek for a number of years. This paper develops a planning framework for restoring and/or rehabilitating Stroubles Creek within the Town of Blacksburg. The results of stream monitoring and other research by SCWI are used to inform the recommended planning process, while a literature review and discussion of “urban stream restoration case studies” are used to guide future decision-making related to Stroubles Creek restoration/rehabilitation. / Master of Urban and Regional Planning
