Drought is one of the severest natural hazards that seriously threatens sustainable water resource management, agriculture, and socioeconomic sectors within a changing climate context. This study investigates drought simulation through rainfall-runoff modelling over a 60-year period within the Cuneo district of Italy. The research herein discussed leverages the TUW model lumped conceptual rainfall-runoff model with semi-distributed operational capability. Similar in structure to the widely used Hydrologiska Byråns Vattenbalansavdelning (HBV) model, the TUW model operates on a daily timestep for both input and output data specific to each catchment, incorporating key routines for snow accumulation, snowmelt, soil moisture storage, and streamflow generation.
