Precipitation and Streamgage Flood Warning System

Science Center Objects

Rainfall amounts associated with the September 2013 Colorado Floods exceeded 15 inches in some locations and resulted in significant flooding along the Front Range (Hydrometeorological Design Studies Center, 2013). These events resulted in streamflows that compromised a variety of transportation structures such as bridges and culverts and roadways.

By coupling the National Oceanic and Atmospheric Administration, National Weather ServiceĀ  Quantitative Precipitation Forecasts with the U.S. Geological Survey (USGS) Precipitation Runoff Modeling System, the USGS will evaluate the feasibility to predict event and site-specific streamflow magnitudes and hydrodynamic thresholds (water depth, velocity, shear stress, and shear velocity) at scour-critical structures such as bridges and culverts for forecasts up to 7 days in advance.
