As a direct impact, the increase of cemented areasreduces the available storage volume for water in the watershed, which in turn exacerbates the runoff generation.Additionally, drainage pathways can be altered and the travel time to the watershed outlet considerably speededup, with impacts on the hydrograph characteristics. The complex interactions among different hydrologicalprocesses make the estimations of the hydrological changes highly non linear.The aim of this work is using an advanced physically-based and distributed model, i.e. tRIBS (TIN-basedreal-time integrated basin simulator), to evaluate how the changes in the hydrological properties affect thewatershed response not only in terms of outlet discharge but also in terms of spatial distribution of the mainhydrological variables (e.g., soil moisture patterns, groundwater level, etc...).Moreover, we evaluate whether and how the spatial pattern of the impervious areas increase affects thechange in the hydrological response.The work has been carried out on the Baron Fork watershed, located in OK (USA), characterized by an area ofabout 800 km2 and for which the tRIBS model was successfully calibrated in the past. Specifically, we eval-uate the hydrological response for different extreme events typical of the area and different land-use configurations.
