What is NetMap?

NetMap is designed to analyze watershed attributes and processes by focusing on the relationships between terrestrial or hillslope properties (erosion, wood recruitment, roads etc.) and stream channels and the routing of that information downstream through a channel network. One example of this approach is the prediction of erosion on hillsides (by various processes) and transferring sediment downstream through a channel network.

Conventional watershed analyses or assessments conducted by federal, state or local governments and by the private (resource management) sector typically take the form of a one time study that produces a report (paper copy and PDF) that resides in an office or on a website. There is little opportunity to update watershed analyses since funding is often a singular opportunity.

NetMap is a “community based” watershed analysis system. “Community” refers to the wide range of stakeholders that have varied interests in the watershed sciences and applied watershed management involving forestry, fisheries, wildfire, monitoring, restoration, research and education. Advantages of community based watershed science system include:

NetMap is a community based watershed science system comprised of uniform digital watershed (map) databases, analysis tools, and technical support materials. The state of the art, desk-top analysis tools contain approximately 70 functions and 80 parameters and they address fluvial geomorphology, aquatic habitat development, erosion, watershed disturbance, road networks, wildfire, hydrology, and large wood in streams, among other processes and attributes. NetMap is designed to integrate with ESRI ArcMap 9.2/9.3 and with non-proprietary GIS systems.
