Interactive spatially dynamic framework for sustainable watershed phosphorus management.

CSREES.

Runoff from agricultural, forested, and residential land uses contribute to the phosphorus problem in Lake Champlain. This project will develop a modeling/GIS analytical framework to facilitate the evaluation of long-term spatial and temporal dynamics of alternative P management scenarios. To date the project has linked 2 computer models with GIS for estimating long term phosphorus concentration in a watershed. The project will then proceed to analyze different management secnarios which are being developed. This project will provide policymakers information on the long-term impact of phosphorus management scenarios as compared to short-term projects. In addition, the project will provide an improved analytical framework that policymakers can apply in other Northeast watersheds. (R. Parsons, W. Jokela, A. Cassell, L. Wood, D. Meals, D.
