The River Bathemetry Tollkit (RBT) enables processing of high resolution DEMs of river channels and makes it possible to efficiently characterize in-stream and floodplain geomorphology to support aquatic habitat analyses and numerical models of flow and sediment transport.
The National Stream Internet pages contain shapefiles of the NSI stream hydrography network and are available for download by NHDPlus version 2 production units; as are shapefiles of prediction points that can be used to make predictions at unsampled locations and map the results of SSN analyses.
The NorWeST webpage hosts stream temperature data and geospatial map outputs from a regional temperature model for the Northwest U.S.
The Climate Shield Cold-Water Refuge Streams Digital Maps & ArcGIS Shapefiles hosts High-resolution NorWeST temperature scenarios are used to highlight climate refugia for preserving native trout populations.
The Geomorphic Road Analysis and Inventory Package (GRAIP) is designed to help land managers learn about the impacts of road systems on erosion and sediment delivery to streams.
The Stream Temperature Monitoring and Modeling interactive maps provide spatial index to nearly 3,200 sites on streams and rivers in the U.S. and Canada where full year stream temperatures are currently being monitored by numerous agencies.
Spatial Stream Network (SSN) for streams provide a new set of analytical tools that can be used to improve predictions of physical, chemical, and biological characteristics on stream networks. These models are unique because they account for patterns of spatial autocorrelation among locations based on both Euclidean and in-stream distances. Includes GIS tools and data.
The Valley Confinement Algorithm (VCA) is a GIS based program that uses NHDPlus data to delineate unconfined valley bottoms. This webpage provides access to the VCA ArcGIS Toolbox script and documentation describing the program.
