Resumen: Flood-control reservoirs are crucial for mitigating flood risks. When linked to flood-prone river reaches, 2D numerical models that capture river-reservoir dynamics are essential. However, 2D reservoir discretization requires many cells, being areas with near-zero velocity. This study introduces a 2D-0D coupled model, combining a 0D reservoir representation with a 2D shallow water model for the river and incorporating a PID control for reservoir level regulation based on dam height. The aim is to improve computational efficiency without sacrificing the accuracy of fully 2D models, water level control in the reservoir. Test cases reveal similar accuracy between the two models, with the 2D-0D approach offering substantial computational benefits. Realistic scenarios confirm these findings, yielding an effective, accurate tool for such applications.
