Assessing streamflow forecast accuracy for flash flood events in Puerto Rico Journal of Hydrology: Regional Studies

A comprehensive understanding of the hydrological cycle is crucial, where models play a key role in monitoring and predicting flood events, enabling better analysis of event behavior. This study evaluated the National Water Model version 2.1, currently operated and monitored by the National Oceanic and Atmospheric Administration. The study focused on assessing the model's ability to produce reliable streamflow forecasts in Puerto Rico, which was recently added to the model in 2021. The evaluation was conducted with five significant rainfall events, including four flash floods and one hurricane in 2022. The forecasted streamflow was determined using 83 river gauge measured data across Puerto Rico during each event. Grant no. NA16SEC4810008 Grant no. NA22SEC4810016
