Abstract

This HydroLearn module provides the skills needed to use the terrain-driven Height Above Nearest Drainage (HAND) approach for efficient, low-overhead Flood Inundation Mapping (FIM). By integrating Synthetic Rating Curves (SRCs) with retrospective and real-time streamflow data from the NOAA National Water Model (NWM), participants can model historical flood events. The course connects the principles of open-channel hydraulics with automated geospatial processes necessary to prepare the terrain-based model, culminating in a practical emergency management simulation. In this final exercise, learners evaluate parametric uncertainty to determine critical evacuation boundaries and safeguard essential infrastructure during a major hurricane scenario.
