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 observations and five climate projections for three periods: 1985-2005, 2041-2060 and 2080-2099. More details on the installation of the JAMS modeling platform is provided in the README file.
