We'd love to hear from you.


QNSPECT is a screening tool used to estimate runoff values for nonpoint source pollution and erosion, and to compare how these values might change under a different land-use or management scenario. This tutorial provides background information, guides you through the tool’s set-up process, and offers practice exercises to help you feel more comfortable using the tool. Tool functions simulate surface water runoff, erosion, nonpoint source pollution, and the accumulation of these conditions downslope and downstream. QNSPECT, a QGIS plug-in, is applicable for coastal and non-coastal areas.
