The Rhetorical Ecology of an Urban Wetland Complex
… Watershed, is a thirty square-mile urban and estuarine wetland in northeastern New Jersey on the outskirts of New York City. As urban wetlands have become a priority in the field of environmental management, this dissertation traces the rhetorical ecology of one such contested site …

Characterization of urban wetland vegetation and management practices
<p>Urban wetlands are important ecosystems that moderate flooding risks and improve water quality. Vegetation is a key component of urban wetlands; plants promote sedimentation, play critical roles in biogeochemical cycling, and provide food and habitats for other organisms. My research focuses on …

Analysing peak flow attenuation in an urban wetland
Worldwide urbanization and climate change are influential in changing precipitation patterns and hydrological flow resulting in event driven urban flooding. The approach to flood protection has recently shifted from engineered and technical solutions to more sustainable and integrated solutions, by …

Measurement of sediment oxygen demand in a created urban wetland
… the sediment oxygen demand (SOD) of a created urban wetland, the cause of differences between SOD methods, and the effect of temperature on the rate of exertion of SOD. <i>In situ</i>, laboratory tank, and laboratory core methods were employed to measure the SOD. It was observed that the main …

Development of the Urban Wetland Filter for Managing Phosphorus in Stormwater
… Natural treatment strategies such as constructed wetlands (CW) demonstrate effective and economical P management but obstacles exist to implementation. Biological P removal has large land requirements that limit the use of best management practices (BMP) in high land-value areas. Various BMP also …

A Knowledge-based approach of satellite image classification for urban wetland detection
… been a technical challenge to accurately detect urban wetlands with remotely sensed data by means of pixel-based image classification. This is mainly caused by inadequate spatial resolutions of satellite imagery, spectral similarities between urban wetlands and adjacent land covers, and the …

Multi-scale analysis of urban wetland changes using satellite remote sensing techniques
This study investigates urban wetland-cover changes in the Kansas City metropolitan area with analyses at various spatial and temporal scales. Not many studies fully addressed multi-scale urban wetland-cover dynamics in both the temporal and spatial dimension. The objective was to understand how …

Princess Vlei : what diatoms can tell us about spatial and temporal heterogeneity in an urban wetland
Globally, wetlands are being degraded and destroyed largely as a result of anthropogenic activity. Monitoring and assessment are required to maintain functional ecosystems and the valuable services they provide. Surface sediment cores were taken from 4 points around an urban wetland (Princess Vlei) …

Coastal sedge/grass meadow restoration in a peri-urban wetland via alteration of environmental filters: can hydrological constraint be trumped?
Stabilized lake-level influence on Typha x glauca has so diminished the extent and richness of Lake Ontario shoreline sedge/grass meadows that they no longer conform to an historic trajectory. These conditions are not likely to change in the foreseeable future, so novel actions may be required to …

Amphibian urbanism in Dhaka’s contested wetlands
Wetlands provide several ecosystem services and are globally critical infrastructure in the era of manufactured climate change. With rare exceptions, planners and policymakers have neglected urban wetlands. In this research, I delve into the complex relationship between urbanization and wetlands …

An analysis of the ability of small urban wetlands to treat stormwater: the case of Princess Vlei wetland, Cape Town
The consequences of poor water quality on urban aquatic ecosystems have been well established by researchers worldwide. Stormwater management in the urban areas of South Africa predominately focuses on the collection and diversion of runoff into the nearest receiving water body, with little …
