GIS-Based Hydraulic Model Spatial Data Layers
Spatial data layers of stream crossing point locations, watershed polygon, cross-section polyline, centerline polyline, and bank polyline shapefiles have been developed for 30 stream crossings in Massachusetts. The spatial data and calculated attribute values are model input data for U.S. Army Corps of Engineer’s Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models. The automated geographic information system (GIS) processes delineated a series of stream channel cross-sections along lidar-derived stream centerlines and have stream channel bathymetry and stream bank polylines estimated using Massachusetts bankfull channel geometry equations (Bent and Waite, 2013). The stream-crossing locations and associated watersheds with output model data will be hosted on U.S. Geological Survey StreamStats web application for Massachusetts https://streamstats.usgs.gov/
This data release contains the following files:
1. Spatial_Data_Layers.zip file containing multiple shapefiles:
a. Stream_Crossing_Locations.shp - Esri point shapefile derived from the NAACC stream crossing database containing all model input and output data values.
b. Model_Watersheds.shp - Esri polygon shapefile of lidar-derived watershed boundaries that estimate the upstream drainage area for each stream crossing location.
c. Model_Cross_Sections.shp - Esri Z- and M-enabled polyline shapefile of the cross-section data used for hydraulic model input.
d. Model_Flowpaths.shp - Esri Z- and M-enabled polyline shapefile of the stream centerline and stream bank line data used for hydraulic model input.
2. Stream Crossing Model Data Dictionary.csv - Descriptions for all attribute columns in the Stream_Crossing_Locations.shp
