Abstract: The Rambla Salada, with an approximate drainage area of 133 km2, is a torrential sub-basin within the Segura River basin and exhibits a high susceptibility to flash-flood events due to the marked irregularity of precipitation and the low permeability of its soils, conditions that are characteristic of semi-arid Mediterranean catchments. Currently, the Segura River Basin Authority (CHS) provides a hydrological study based on the semi-distributed HEC-HMS model. However, the availability of high-resolution LiDAR topographic data and the increasing use of advanced fully distributed hydrological modeling approaches highlight the need to compare modeling frameworks and update the estimation of design flood discharges. This work proposes a comparative analysis between a semi-distributed hydrological model implemented in HEC-HMS and a fully distributed model developed using IBER, employing design storm events corresponding to different return periods. The numerical results of the study are currently under development and will be presented at the conference.
