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 Service 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.

Uncertainty in remote sensing of streams using noncontact radars
Accounting for freshwater resources and monitoring floods are vital functions for societies throughout the world. Remote-sensing methods offer great prospects to expand stream monitoring in developing countries and to smaller, headwater streams that are largely ungauged worldwide. This study evaluates the potential to estimate discharge using eight radar units that have been installed over streamsNear-field remote sensing of surface velocity and river discharge using radars and the probability concept at 10 USGS streamgages
Near-field remote sensing of surface velocity and river discharge (discharge) were measured using coherent, continuous wave Doppler and pulsed radars. Traditional streamgaging requires sensors be deployed in the water column; however, near-field remote sensing has the potential to transform streamgaging operations through non-contact methods in the U.S. Geological Survey (USGS) and other agencies - Partners
