Abstract: Studying the continental water cycle is essential to understand water availability and favor sustainable management under changing climatic conditions. Land surface models (LSMs) play a key role in representing water and energy exchanges between the atmosphere, soil, and vegetation, enabling detailed simulations of both natural and human-influenced hydrological processes. This work presents the SASER hydrometeorological modeling chain, which integrates the SAFRAN atmospheric forcing, the SURFEX LSM, the Eau-Dyssée modeling platform, and the RAPID river routing, to simulate the continental water cycle in the Iberian Peninsula, with focus on the Ebro basin. In addition, a recently implemented irrigation scheme in SURFEX enables representation of irrigated areas. The framework allows assessment of how climate change may alter hydrological dynamics and water distribution across natural and partially anthropized systems.
