Hydraulic Model Data for Selected Stream Crossing Sites in the Squannacook River Basin, North-Central Massachusetts The U.S. Geological Survey (USGS) collected field survey data and developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models for selected stream crossing sites in the Squannacook River Basin, north-central Massachusetts. A Geographic Information System (GIS) was developed to derive model input data from Light Detection and Ranging (lidar) Digital Elevation Models (DEM) at each stream crossing location. Hydraulic models were built for existing culvert designs as well as preliminary culvert designs for a 3-sided box, 3-sided arch, and a pipe culvert using field survey and GIS data. The preliminary culvert models were designed to convey...

The surveyed stream cross sections and culvert dimensions were used in developing U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models. The data also include original survey notes, survey sketches, and photographs for each field survey conducted at stream crossing locations. The field survey documented and surveyed five stream cross sections for the upstream approach, upstream culvert face, top of road deck, downstream culvert face, and downstream exit.

The child item named “Hydraulic model data for selected stream crossing sites in the Squannacook River Basin, North-Central Massachusetts” contains U.S. Army Corps of Engineers’ Hydrologic Engineering Center River Analysis System (HEC-RAS) hydraulic model files along with field survey data associated with each stream crossing location. This data release also includes a data dictionary defining culvert designs, site locations, modeled flows and water surface elevations, and aquatic habitat...

Wildlife Biology, Fewer tags Spatial Data Layers for Selected Stream Crossing Sites in the Squannacook River Basin, North-Central Massachusetts Spatial data layers of stream crossing point locations, cross-section polyline, centerline polyline, and bank polyline shapefiles have been developed for selected stream crossings in the Squannacook River basin, 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 stream crossing point locations were derived from the North Atlantic Aquatic Connectivity Collaboration (NAACC) database. The stream channel cross-sections, centerlines, and bank polylines were derived using automated methods in a Geographic Information System (GIS) using ArcGIS Pro and Python programming...
