Impact/Purpose:
This report is a review of stormwater computer models. It provides details of 26 different models, and addresses the environmental problem of a wide-area biological or radiological contamination release. It also evaluates different stormwater models for their capacity to be modified for use as a fate and transport tool for an emergency response to a contamination incident. This report is useful for stormwater utilities, consultants and emergency responders.
Description:
If a terrorist event or natural disaster causes a wide area of land to be contaminated with chemical, biological, or radiological particulates, emergency responders need a rapid way to determine where to sample and decontaminate prior to clearing the area. A comprehensive stormwater model review that is focused on the needs of those remediating after such a release does not exist. This report presents a variety of modeling tools that are used for understanding the fate and transport of stormwater and associated pollutants in more routine applications. These existing modeling tools are expected to need modification from their existing formats to serve the needs of the emergency response and remediation community. Therefore, criteria specific to emergency response modeling are outlined in Section 3 of this report, and this report provides two appendices with detailed model information. The criteria include aspects such as ease of assembly during an emergency event, how prevalent the tools currently are (which would facilitate model repurposing), and if modifications to the source code are possible or if the source code is proprietary.
