dc.description.abstractOnsite and Earth observation (EO) data are used for the calibration of the Natural Resources Conservation Service curve number (NRCS-CN) value in a hydrological simulation model. The model was developed for La Muga catchment (eastern Pyrenees) highly vulnerable to flood and drought episodes. It is an integral part of a regional reservoir management tool, which aims at minimizing the flood risk while maximizing the preservation of water storage. The CN values were optimized for five recorded events for the model to match the observed hydrographs at the reservoir when supported with the measured rainfall intensities. This study also investigates the possibilities of using antecedent moisture conditions (AMC) retrieved from satellite data to inform the selection of the NRCS-CN losses parameter. A good correlation was found between the calibrated CN values and the AMC obtained from satellite data. This correlation highlights the interest in using EO data to update NRCS-CN estimates. This advances in hydrologic-hydraulic coupled modeling combined with new remote sensing datasets present valuable opportunities and potential benefits for flood risk management and water resources preservation.
dc.description.sponsorshipThis work was carried out in the framework of the PGRI-EPM project (Prévision et gestion du risque d’inondation en Eurorégion Pyrénées Méditerranée) funded by the call for projects “Water Resources–Risk Management (Floods, Droughts, Submersion)” of the Pyrenees-Mediterranean Euroregion. The authors also thank to the Agència Catalana de l’Aigua and Servei Meteorològic de Catalunya, who provided the rainfall and water-level data, as well as its advisement during the project.
