UI center has flood maps for Iowa

December rains are causing trepidation across Iowa. Temperatures far above seasonal averages and a heavy dose of rainfall have inundated the state with water, at a time of year when the extra moisture yields more runoff than usual. Since this weekend, about 100 flood warnings have been issued across Iowa as creeks, streams, and rivers… Continue Reading »

Mapping Outlets of Iowa Flood Center and National Water Center River Networks for Hydrologic Model Comparison

The authors propose a methodology to find corresponding outlets where the hydrologic simulations of the IFC model, and the National Water Center model, can be compared. F. Quintero and W. Krajewski. “Mapping Outlets of Iowa Flood Center and National Water Center River Networks for Hydrologic Model Comparison,” Journal of the American Water Resources Association, DOI: 10.1111/1752-1688.12554,… Continue Reading »

Analysis of National Weather Service Stage Forecast Errors

The authors report the skill of the river stage forecasts produced by National Weather Service at 51 locations in Iowa. They also analyze how the skill obtained at particular locations is related to the characteristics of the basin. G. Zalenski, W. Krajewski, F. Quintero, P. Restrepo, and S. Buan. “Analysis of National Weather Service Stage… Continue Reading »

A Spatial–Dynamical Framework for Evaluation of Satellite Rainfall Products for Flood Prediction

The authors report a novel framework that provides insights about the spatial and temporal propagation of errors in hydrologic simulations across the drainage network. F. Quintero, W. Krajewski, R. Mantilla, S. Small, and B.-C. Seo. “A Spatial-Dynamical Framework for Evaluation of Satellite Rainfall Products for Flood Prediction,” Journal of Hydrometeorology, 17, 8, pp., 2017. doi.org/10.1175/JHM-D-15-0195.1
