Nonpoint-Source Pollution and Erosion Comparison Tool
Provided by the NOAA Coastal Services Center
Use the Nonpoint-Source Pollution and Erosion Comparison Tool (N-SPECT) to investigate potential water quality impacts from development, other land uses, and climate change. N-SPECT was designed to be broadly applicable, but the tool operates most accurately in medium-to-large watersheds having moderate topographic relief.
New publication describes regional pollutant coefficient development
Features
- Provides projections and maps of surface water runoff volumes, pollutant loads, pollutant concentrations, and total sediment loads
- Helps users see areas that might benefit from changes to proposed development strategies
- Processes digital elevation data quickly and easily
- Provides a means to analyze "what if" land use change scenarios
N-SPECT version 1.5.0 is now available
