This is the dataset for developing the HAND-RAS workflow mentione in the manuscript "Establishing Synthetic Rating Curves by Integrating the Height Above the Nearest Drainage with Hydrodynamic Computation". In the manuscript, we used the topographical cross-sectional survey data to generate topographical synthetic rating curves (T-SRCs) to validate the performance of the HAND method based synthetic rating curves (HAND-SRCs) produced by the HAND-RAS workflow.
