linking-hms-to-hecras

Features and purpose

Links HEC-HMS watershed models to HEC-RAS river models by extracting HMS DSS results and preparing them for RAS boundary condition import. Handles flow hydrograph export, spatial referencing (HMS outlets to RAS cross sections), DSS pathname formatting, quality validation, and time series alignment. Use when setting up HMS→RAS workflows, exporting HMS results for RAS, preparing upstream boundary conditions, or coordinating watershed-to-river integrated modeling. Leverages shared RasDss infrastructure for consistent DSS operations across both tools. Trigger keywords: HMS to RAS, link HMS RAS, boundary condition, upstream BC, watershed to river, integrated model, export HMS, DSS pathname, spatial matching, hydrograph.
