Stream Reach Evaluation and Metrics - Geometry (STREAM-geo)

STREAM-geo provides river geometry data for nearly 2.7 million NHDPlus stream reaches across the contiguous US. This newly assembled dataset provides, to our knowledge, the best available predictions of river width and river depth for all NHDPlus stream reaches. In addition to river depth and width, STREAM-geo also provides both reach-scale predictions of the river width-to-depth ratio and river surface area, and HUC8-scale estimates of the percent river and stream surface area (%RSSA). This dataset is derived from our river geometry data-driven approaches, using publicly available catchment and channel characteristics datasets, and an unprecedentedly large continental-scale river geometry observation database.
