Importance of uncertainty analysis (UA) to estimate the degree of reliability associated with model predictions is being understood. Consequently, literature that describes various Bayesian methods for the assessment of parameter and model predictive uncertainty has been steadily rising. Applications dealing with urban stormwater management are, however, very limited. This study demonstrates su...

typically, best management practices (bmps) are implemented to help sustainable stormwater management in urban areas. over recent decades the selection of urban stormwater management measures for a site has been a challenge among urban planners where thecriterion based on flood volume no longer suffices for selecting urban drainage solutions. therefore there is a need to consider a set of holis...

While there are many resources available to aid in the design and construction of most structural stormwater Best Management Practices (BMPs), there are few guides pertaining to their operation and maintenance. Historically, it seems as though “build-em” and walk has been common-place. However, increasing focus upon mass balances, numeric goal setting and Total Maximum Daily Loads (TMDLs), now ...

Detention ponds are currently accepted as stormwater best management practices (BMPs) in coastal South Carolina. These ponds are typical catch basins for stormwater piped directly from impervious surfaces in many residential and resort areas. Nutrients often concentrate in the ponds and contribute to eutrophication within the ponds and downgradient estuaries. A supplementary BMP is proposed tha...

Stormwater is recognised as a large contributor of toxic substances to receiving waters. Different measures to manage stormwater quality have been proposed, including structural and non-structural best management practices (BMPs). Computer models have become useful tools for the analysis, evaluation and design of these BMPs. The main objective of this study was to develop a modelling framework ...

v * Corresponding author: [email protected] Rapid urban expansion, increased traffi c, ageing infrastructure, greater climatic variability, and the need for enhanced sustainability of urban water resources pose signifi cant challenges to conventional stormwater management. Innovative approaches are needed in order to mitigate the risk of fl ooding, pollution, and aquatic ecosystem degradat...

Since passage of the Clean Water Act, federal, state, and local governments together with the private sector have spent billions of dollars attempting to meet the act’s goals of restoring and maintaining the chemical, physical, and biological integrity of the nation’s waters. While great progress has been made, especially with respect to reducing traditional point sources of pollution, we are f...

this study examines the relationship between land use/land cover (lulc) changes and surface runoff generation empirically to reveal how urbanization has altered the hydrologic characteristics of a watershed. a hydrological model, the soil and water assessment tool (swat), is employed to estimate the watershed runoff generation for two lulc scenarios from 2002 to 2010. the cypress creek watershe...

Applied Ecological Services, Inc., has designed, engineered, constructed or overseen the construction of numerous wetland biofiltration projects. Project goals have been to clean up macronutrient-burdened water from industrial sources, agricultural systems and sewage treatment facilities. Septic management has been involved in many projects where biofilters have been created to manage stormwate...

Owing to overflows from combined sewer pipe systems, water quality of receiving waters, including urban rivers, has become worse year by year. Appropriate countermeasures that can mitigate the overflows, therefore, must be developed promptly. The authors have investigated a distributed simulation model of water quality and stormwater runoff in urban sewer pipe systems. First, a surface routing ...
