Evaluation of remotely sensed precipitation product in a hydrological model of the Bednja watershed

Karlo Leskovar, Petar Mrakužić, Hrvoje Meaški

Abstract

In this paper, a statistical and spatial analysis of precipitation for the period 2000-2018 for the Bednja watershed was performed, were the measured data from meteorological and/or rainfall stations of Croatian Meteorological and Hydrological Service (DHMZ) were compared with the data in form of remotely sensed precipitation product - CHIRPS (Climate Hazards Group InfraRed Precipitation with Station). The results of the analysis in the form of the annual sum, monthly distribution within the year and the spatial distribution and input data ratio over the basin show a good correlation between the measured and remotely sensed precipitation. In order to further evaluate the quality of the remotely sensed product, a SWAT hydrological runoff model was created. The model was calibrated, and the results were validated on an independent data set.
