Previous study · Navajo Nation
Using simple methods to prioritize advance flood mapping capabilities for the Navajo Nation.
- Flood mapping & hydraulics
Use of simple large-scale flood models to prioritize deployment of HEC-RAS 2D model for the Navajo Nation. This concept allows for resources to be wisely used in the areas where they are needed the most.
The above flood inundation maps helped prioritize where HEC-RAS 2D models were required.

Follum, M. et al. (2019). “Utilizing Simple Large-Scale Flood Models to Prioritize Deployment of HEC-RAS 2D Models: Case Study of Navajo Nation Flood Inundation Maps”. Flood Risk Management Newsletter, 12, 4–7.
Why it matters: limited modeling dollars went to the places that needed detailed flood models the most.
