How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Bioretention systems have become a leading infiltration-based Low Impact Development (LID) practice to reduce urban stormwater runoff volumes and peak flows. Although these systems have performed well in many site-scale field studies, modeling of bioretention systems has received less attention. Additional studies are needed which calibrate various...
Many bioretention models still incorporate simplifications and lumped parameters that do not fully account for fundamental physical processes. This review summarizes the representation of hydrologic pathways, notable features, and applications of bioretention models with the goals of recommending models well suited to bioretention modeling and iden...
Bioretention systems have become a leading stormwater control measure for mitigating urban hydrology. Although these systems have performed well in many site-scale field studies, less investigation has been directed toward effectively modeling these systems. This is critical, as modeling of bioretention systems provides an avenue for evaluating the...
Urban runoff and stormwater is one of the top ten leading causes of water quality impairment in lakes, estuaries and streams in the United States (USEPA 2009). Over the last decade, bioretention systems have become a leading stormwater control measure (SCM) that contributes to the restoration of urban streams and watersheds. Bioretention cells incr...
Across the United States, the impacts of stormwater runoff are being managed through the National Pollutant Discharge Elimination System (NPDES) in an effort to restore and/or maintain the quality of surface waters. State transportation authorities fall within this regulatory framework, being tasked with managing runoff leaving their impervious sur...
Hydrologic models are often used to predict erosion and the influence of land cover changes on sediment detachment within a watershed. One such model, the Water Erosion Prediction Project (WEPP), determines the runoff and sediment yield of a given hillslope using input data including slope, climate, soil, and land management. WEPP accepts user inpu...
This project evaluates how changing land use and climate will affect BMPs in both agricultural and urban areas. Which BMPs will prove most effective under these conditions?
We are modifying DRAINMOD to better model urban hydrology by adjusting the time scales for input and output data. We will model two bioretention Silva Cells being monitored on UT campus using both the previous and updated versions of DRAINMOD.
