ABSTRACT
The rainfall anomalies are produced by tropical waves, low pressure depressions, tropical storms, and hurricanes capable of producing flash flood in susceptible areas. As part of the model configuration, rainfall must be distributed over the model domain. New emerging radar technologies are being developed by the Student Test Bed of the Center for Collaborative Adaptive Sensing of the Atmosphere in Puerto Rico and will be available for flash flood predictions. This new radar technology promises to revolutionize the way rainfall is detected, monitored and predicted, creating a dense sensor network of low-powered radars that overcome curvature blockage and significantly enhance resolution. One important contribution will be to find the rainfall product uncertainty over small watersheds. Also, evaluate how uncertainties due to quantitative precipitation estimates at different resolutions below 2 kilometer from point rainfall are propagated though the hydrologic solution.
