Analysis Of Pervious Concrete As A Stormwater Management Tool Using Swmm Modeling
… the epa stormwater management modeling tool (swmm) to quantify the volume of runoff that can be expected from different intensity storms with various pervious concrete pavement area coverage and infiltration rates. Based on the infiltration rate test results the average infiltration rate of …

Urban hydrological modeling of the Malden River using the Storm Water Management Model (SWMM)
… the River. The Storm Water Management Model (SWMM), developed by the Environmental Protection Agency (EPA), was used because it was deemed the most appropriate of the readily available models for this urban setting. This model characterizes the impervious nature of the land surface in the …

Development of a SWMM-GIS Flood Model for New Orleans Drainage Pumping Station No 4 Basin
… needed to develop a stormwater management model (SWMM) integrated with GIS that includes a Damage Model to estimate the losses produced by storm events on flood prone areas. The latest LIDAR data are used for the topography. The drainage area for this study covers approximately 3218 acres, with …

Hydrologic Evaluation of Low Impact Development Using a Continuous, Spatially-Distributed Model
… Review of available models revealed EPA-SWMM 4.4H as the most applicable to the task. A 4.3-acre subwatershed of a local subdivision was adapted to LID using impervious surface disconnection, forest retention, and IMPs. SWMM was applied to the LID development at a fine spatial scale, …

Modelling the hydrological response of an urban watershed Diachronic analysis of the effects of land use changes on storm runoff generation in the Upper Bukit Timah basin, Singapore
… the impacts of urbanisation on hydrology. The SWMM model, a one-dimensional physically based model especially developed for urban areas, was mainly used. The parameters encoded into the model were determined by different means and several methods were used for their determination in order to …

Using Geophysics and Terrestrial LiDAR to Assess Stormwater Parameters in Vacant Lots in Philadelphia
… Agency’s Storm Water Management Model (SWMM) to predict runoff and evaluate if proposed stormwater infrastructure will reduce overflows. This study focused on the hydrogeological properties of grassy areas on and near Temple University’s main campus in north Philadelphia. The dataset …

Integrated Modeling and Optimization of Stormwater Control Measures for Sustainable Watershed Management Under Urbanization and Changing Rainfall Patterns
… coupled models are essential. While SWAT and SWMM are widely used for runoff simulation, neither can independently represent both urban and rural hydrology. Moreover, most studies assess either CC or land use/land cover (LULC) change in isolation, overlooking their combined effects. This …

Time characteristics of small watersheds in response to the probable maximum precipitation
<p>"The EPA Storm Water Management Model (SWMM) was used to perform single event simulations of Probable Maximum Precipitation (PMP) level rainfall events on the Loss Lake watershed in southcentral Missouri. Overland flow was simulated using kinematic wave routing and channel flow was simulated …

Extended stormwater detention basin design for pollutant removal
… is generated from Storm Water Management Model (SWMM) simulations and shown to be independent of runoff statistics, pond configuration, and arbitrary but constant influent concentration under complete mixing. The analytical detention time estimate, in combination with the settling efficiency …

The Use of Stormwater Modeling for Design and Performance Evaluation of Best Management Practices at the Watershed Scale
… To address this, a model is developed using EPA SWMM 5.0 for the Duck Pond watershed, which is located in Blacksburg, Virginia and encompasses much of the Virginia Polytechnic and State Institute's campus and much of the town of Blacksburg as well. A variety of BMPs are designed and placed within …

Sensitivity of Stormwater Management Solutions to Spatial Scale
… Protection Agency’s Stormwater Management Model (SWMM) was selected for this study. It is well recognized that model predictions are plagued by uncertainties that arise from the lack of quality data and inadequacy of the model to accurately simulate the watershed. To scrutinize sensitivity of …

Modelling the Hydrologic Impact of Land Cover on Stormwater Detention Basins in Harris County, TX
… Agency’s Storm Water Management Model (EPA SWMM). Five significant rainfall events and annual simulations over a 10-year period (2015–2024) were modeled across ten basins with varying land cover conditions. Results showed that land cover significantly alters surface hydrology. Tree-covered …
