Calibrated and validated J2000P hydrological model of the Claduègne catchment at hourly timestep, representing natural processes and human activity (i.e. drinking water extraction, waste water and urban overland flow injection, irrigation and livestock water consumption and excretion). Model, input and output for two climate projections and three land use land cover scenarios for the mid-century (2050 LULC and 2041-2060 climate), as well as the historical reference (2020 LULC and 1985-2005 climate). More details on the installation of the JAMS modeling platform is provided in the README file.
