Quantitative Precipitation Estimates and Observations: How Good are they for Robust Hydrologic Modeling and Design?

10 am - Politecnico di Torino, Bibolini Classroom, DIATI Entrance 3, ground floor


Accurate measurements of precipitation that characterize its spatial and temporal variability in a region are quintessential for the success of hydrologic modeling and design. Point measurements (i.e., rain gage observations) often plagued with systematic and random errors while lacking spatial coverage are questionable inputs to hydrologic design procedures and inadequate for distributed hydrologic modeling applications. Multi-sensor source-based quantitative precipitation estimates (QPEs) developed as gridded datasets/products are increasingly being used by hydrological modeling and design communities. This talk will focus on QPEs developed using weather-surveillance radar (WSR) using rain gage information as ground truth and will address issues related to the generation of radar-based precipitation estimates, Improvements in QPEs, bias analysis, and correction methods. The utility and validity of these QPEs for hydrologic modeling, design, and hydrosystems management will be discussed.
