Water from the snowpack drives the rivers in for much of the World and can be a large contributor to flooding. Historically, snow has been difficult to simulate due to limited data availability for both forcing and calibrating the numerical methods.

GIS Profile Tool Pulls elevation profiles parallel to major roadways Python Gap Locator Tool Finds high and low spots along the elevation profile. Finds embankments for each gap. Outputs bridge width information, Line Shape files. Gap-crossing is one of the largest concerns for military transportation.

Dark-blue shows agreement between all of the flood ensemble members. Light blue indicates where only some of the ensemble members indicate flooding to occur. Forecast weather and streamflow models account for uncertainty by utilizing multi-member ensembles. Utilizing each member of the weather ensemble, flow models

Sci. https://doi.org/10.5194/nhess-2019-180. This project developed methods to estimate bathymetry within river channels. It also enabled for improved accuracy

Continental-Scale flood mapping. Image shows hydrography data for South America. This was one of the first efforts to create high-resolution flood inundation maps for the entire continent.

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
