Building a Multi-source Flood Inundation Database and Visualizing HAND and Model-Generated Flood Maps

Building a Multi-source Flood Inundation Database and Visualizing HAND and Model-Generated Flood Maps

Day 1 Session 1 (10:30AM)

Presenters:

Pitamber Wagle, PhD candidate

This workshop demonstrates how to generate, integrate, and visualize flood inundation maps using a unified database framework. Participants will create HAND-based flood maps for a selected area and explore model-generated flood products linked to the database, with all datasets stored and shared through HydroShare. The session highlights how multi-source flood maps can support early warning and strengthen NWM inundation forecasting, while providing hands-on experience with CIROH-supported tools.

Workshop Slides

Learning Outcomes:

  • Generate HAND-based flood inundation maps for a selected area that could be replicated at any location.
  • Access pre-generated model flood maps from the multi-source database
  • Preprocess and optimize flood maps from any source
  • Upload, organize, and share flood datasets using HydroShare
  • Visualize and compare flood maps using FIM Visualization tool
  • Learn about the ongoing research to support depth, velocity, and impact.
