Developed by Dr. David Hyndman (Michigan State University)

Overview

This model is intended to explicitly describe the nutrients applied to the landscape in the Great Lakes region at a HUC 12 spatial scale. The Spatially Explicit Nutrient Sources (SENS) model identifies six nutrient sources: atmospheric deposition, septic tanks, agricultural and non-agricultural chemical fertilizer, animal manure, and point sources. The model assumes that all nutrient sources have been accounted for. The current version does not estimate the load in the stream, but future iterations are expected include transport and fate processes to estimate load within the stream.

Features

• View percent contribution of nutrient sources to the landscape in your 12-digit watershed(s)
• Save or print maps for planning and decision making
