Waller Creek is one of the oldest monitoring sites in the Austin area. First a U.S. Geological Survey site in the 1950s, it is now monitored by the City of Austin through its Texas Pollutant Discharge Elimination System permit. Image credit: COA-WPD-WQM

Monitoring and Modeling: Two Sides of a Coin

The City of Austin is using monitoring and modeling to direct watershed regulations with science and to enhance stormwater control design criteria.

VIMS Modeling Approach Predicts Street-Level Storm Tide

A team of researchers at the College of William & Mary’s Virginia Institute of Marine Science (VIMS), accurately hindcasted Hurricane Sandy’s landfall along the U.S. Atlantic coast using a large-scale, unstructured grid storm tide model, called Semi-implicit Eulerian Lagrangian Finite Element. The researchers used data collected before Hurricane Sandy and tested the results with observations […]

EPA Releases Tools for Managing Water Resources

In November, the U.S. Environmental Protection Agency (EPA) released the Watershed Management Optimization Support Tool. The tool supports integrated water resources management by allowing users to screen options for cost-effectiveness and environmental benefits. With the tool, users can evaluate a number of management options, including projects related to stormwater. Users can conduct an analysis of […]

Model Predicts Regions with Groundwater High in Arsenic

According to a paper recently published in Science, 19.6 million people in China could be at risk from arsenic found in groundwater. Researchers with the Swiss Federal Institute of Aquatic Science and Technology and China Medical University in Shenyang developed a tool that helps to predict areas where groundwater could be high in arsenic. According […]

WERF Releases New Tools and Reports

Flood grouting reduces wet weather sanitary sewer overflows According to a Water Environment Research Foundation (WERF) report released in February, flood grouting is a cost-effective solution that can reduce infiltration into sanitary sewers. In Seattle’s Broadview neighborhood, stormwater and groundwater were infiltrating defects in the sanitary sewer that had accumulated over time, causing wet weather […]

Check it Out! EPA Modeling Tools for TMDLs

The U.S. Environmental Protection Agency (EPA) Hydrological Simulation Program-Fortran (HSPF) model simulates watershed hydrology and the movement of pollutants over pervious and impervious land, as well as instream channels. The accuracy of modeling channel hydraulics is important for proper total maximum daily load estimation. Therefore, EPA created best management practice tools for the model, which […]

WERF Seeks Proposals on Nutrient Modeling

The Water Environment Research Foundation (WERF; Alexandria, Va.) currently is seeking proposals for an applicability analysis of and guidance on existing models for water quality criteria to protect designated uses from nutrient impacts. Proposals are due by Nov. 18 at 5:00 p.m. Eastern Standard Time. WERF recently released a stormwater best management practice (BMP) performance […]
