Location: National Soil Erosion Research2013 Annual Report
1a. Objectives (from AD-416):
Principal focus of the CEAP Watershed Studies is to evaluate the effects and benefits of conservation practices at the watershed scale, in support of policy decisions and program implementation.
1b. Approach (from AD-416):
The effects of conservation activities on water and soil quality will be assessed at the watershed scale using models such as ARS' Soil and Water Assessment Tool, in combination with ARS long-term watershed data sets, expertise, and resources.
3. Progress Report:
The Agricultural Policy/Environmental eXtender (APEX) model was calibrated and validated for the St. Joseph River watershed. Two manuscripts have been submitted for this work. APEX is being applied to assess the impact of conservation practices placed in the St. Joseph River watershed since 2005.
