The continued development of urban areas in recent decades has caused multiple issues affecting the sustainability drainage systems. increase impervious surface regions alters watershed hydrology and water quality. Typical impacts to downstream hydrologic regimes include higher peak flows runoff volumes, shorter lag times, reduced infiltration base flow. Urban increases transport pollutants nutrients thus degrades bodies from areas. One most frequently used practices mitigate these is...
The hydrologic benefits of catchment-scale implementation stormwater control measures (SCMs) in mitigating the adverse effects urbanization are well established. Nevertheless, recent studies indicate that Unified Stormwater Sizing Criteria (USSC) regulations, mandating combined use distributed and storage controls, do not protect channel stability, despite their effectiveness reducing runoff from impervious surfaces. USSC basis SCM design 11 U.S. states District Columbia. This study employed...
Assessing climate change (CC) impacts on urban watersheds is difficult due to differences in model spatial and temporal scales, making prediction of hydrologic restoration a challenge. A methodology was developed using an autocalibration tool calibrate previously Storm Water Management Model (SWMM) Difficult Run Fairfax, Virginia. Calibration assisted by use multi-objective optimization. Results showed good agreement between simulated observed data. Simulations CC for the 2041–2068 period...
New methods are used to evaluate stormwater controls and best management practices (BMPs) within a land development context. Costs developed using published literature standard cost estimation guides. A method is in which costs determined for each parcel specific uses. The effect of including the opportunity analysis evaluated. attributable allocated among purposes. control assigned at level. Data gaps research needs then explored address this complex problem.
The application of geometric information system (GIS) technology to the field urban storm-water modeling is reviewed. Then a GIS in management presented at neighborhood scale. scale includes GIS, database, design template, and an optimization capability for screening alternatives. area soil-type based Soil Conservation Service (SCS) method used calculating runoff from information. Using economic analysis compare cost controls, including opportunity land intensive optimal mix best practice...
This study compares the performance of three bioretention media blends for N and P removal from simulated urban runoff in experimental mesocosms. TerraSolve, Biofilter, "VT Mix" (Virginia Tech) were compared with without vegetation at varying hydraulic residence times (HRTs). Adsorption isotherm experiments also conducted. TerraSolve VT Mix included water treatment residuals (WTRs), Biofilter yard-waste compost (YWC), a mix coir peat. removed highest amount total (>95%), which is attributed...
