Refer to NetMap Portal’s technical help and tutorial. NetMap Portal watersheds only cover a select subgroup of all NetMap datasets, primarily using LiDAR developed after 2017. Searches can be made to identify locations where two attributes overlap, like the highest 1% of coho habitat quality and the highest 10% of erosion potential. Here users can pan, zoom in and out, and search for specific watershed attributes, like the best fish habitats, highest erosion potential, best riparian areas and widest floodplains, among other attributes.

Using ArcGIS requires adequate computer hardware, proprietary software and some experience. NetMap Sediment Budget by Monitoring Subarea Vs. Michael D (2007) NetMap: a new tool in support of watershed science and. NetMap’s virtual watersheds work within an ArcGIS environment as a set of digital shapefiles, and contain information pertaining to river networks, channel environments, floodplains, riparian zones, erosion potential and roads. For example, if the network map contains 25 nodes with API APPLIDs in each of the 25 nodes, it requires approximately the. Parameter Description: NetMaps Channel Sedimentation Model uses either Generic Erosion Potential (GEP) or it conversion form of sediment field (t/km2/yr).
These two confluence-related sediment parameters should be used in conjunction with other confluence and stream parameters in NetMap to estimate the likelihood of encountering confluence effects in watersheds.What is NetMap Portal? Online Watershed Maps 28 + 8 (x) If either PNODE or SNODE.LUS is specified, add 1 to x for each node name specified. netmap is a framework for extremely fast and efficient packet I/O for userspace and kernel clients, and for Virtual Machines.

Thus, higher values of this parameter should be associated with confluences that may have a higher likelihood of creating certain types of depositional environments. NetMap ® uses sophisticated node link analysis and fraud analytics to find connections among massive amounts of data.
The second parameter takes the confluence ratio of sediment supply and divides it by stream power (of the mainstem channel segment where the tributary intersects). The first is the ratio of predicted sediment supply between the mainstem and the tributary (e.g., aggregated GEP of the tributary/aggregated GEP of the mainstem) the lower the ratio, the more likely the tributary can create unique confluence environments in mainstem rivers (e.g., Ferguson et al. Thus, NetMap includes two other parameters that can be used to consider the potential for watersheds to create unique confluence environments. Example of wetland, GEP and area of influence in the study area for: (a). NetMap includes other parameters that characterize the potential for confluences to create unique geomorphic environments (see Parameter Library) but they do not address the issue of sediment supply (i.e., the relative importance of tributary fluxes of sediment compared to the sediment flux of the mainstem) or channel conditions at the confluence that would promote or discourage confluence effects (i.e., channel gradient or stream power). At the same time, we obtained the potential erosion using the NetMap software. In addition to channel-segment based predictions of sediment supply and sedimentation, NetMap includes two parameters designed solely to address confluence related environments.
