Generation of daily flows using the GR4j model and the ERA5 gridded climatic product in the Crisnejas basin up to the Puente Crisnejas hydrometric station

Abstract

Given the lack of hydrometeorological records in the Crisnejas basin, the present study aims to generate the flows on a daily scale in the main channel of the river up to the Crisnejas bridge station based on the ERA5 satellite-based climate grid data and the French precipitation model. GR4j runoff. This will serve as the basis for future hydrological studies in the Crisnejas River. For this work, it has been planned to carry out a calibration, validation and extension of the hydrometric records on a daily basis between the years 1979-2020
