NPS Pollutant Modeling and BMP Evaluation

Objectives

Characterize the non-point source pollutant loadings from

the agricultural watersheds

Identify the areas contributing relatively excessive loadings

at the outlet of the watersheds

Prioritize the sub-watersheds for implementing BMPs
Evaluate the effect of BMPs in reducing the loadings

Tools Being Used

SWAT – Soil and Water Assessment Tool
AnnAGNPS – Annualised AGricultural Non-Point Source
