RAPID to GSSHA¶
It is possible to use RAPID streamflow as an overland flow boundary condition to the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model.
What is GSSHA?¶
GSSHA is a physically-based, distributed hydrologic model. GSSHA is developed and maintained by Coastal and Hydraulics Laboratory (CHL) which is a member of the Engineer Research & Development Center of the United States Army Corps of Engineers (USACE).
For more information about GSSHA please visit the the gsshawiki .
There are two ways to input RAPID as a boundary condition for GSSHA. One is to connect the GSSHA stream network link and node to the RAPID river ID and generate the IHG file. The other is to generate an XYS timeseries file and add it to the netork using WMS.
Method 1: Generate IHG File¶
Method 2: Generate XYS File¶
Step 2.1: Generate XYS File¶
Step 2.2: Add XYS File in WMS¶
