Impact/Purpose:
The objective of this task is to improve modelers' ability to focus on scientific and management issues in modeling studies by providing software that supports evaluating and applying complex systems of models. The objective is to also provide software that enables or supports linking different media models together to better address multimedia issues.
Description:
The potential for atmospheric deposition reductions to contribute to water quality management is not being included in many planning exercises. This is because often the water quality scientists do not know where to get and how to use projections of atmospheric deposition reductions produced by the air regulatory community. A means to facilitate the air-water quality linkage is needed.
To meet this need, a software tool is being developed by NOAA/EPA's Atmospheric Sciences Modeling Division to aid the linkage of air and water for TMDL (Total Maximum Daily Load) and related nonpointsource watershed analyses. The tool is called the Watershed Deposition Tool (WDT).
