A decision support system to evaluate water resource during low water period in South-Western Europe catchments: the AGUAMOD platform

The objective of Aguamod is to work with all stakeholders in water management (managers, economic actors, users and civil society) in South-West Europe (SUDOE) to build a platform for the integrated management of water resources during low water periods. The Aguamod platform combines a calculation of the water needed from the watershed (drinking water, agriculture, industry, environmental flows ...), with numerical models simulating the stocks and fluxes of water in all compartments of the watershed using SWAT model. An economic and social evaluation of water resources and an analysis of water governance was conducted for the SUDOE territory as a whole. Different scenarios of climate change coupled with simulations aimed to anticipate future water needs from a social and environmental point of view. The Aguamod platform (http://www.aguamod-sudoe.eu/handbook/) aims to promote a global and shared vision of this resource when water levels are low in the SUDOE territory. It provides managers and users with tools to support decision-making using complex scenarios, and by 2050 offer robust and spatial information on the dynamics of climate, hydrology, land use, water and modes of governance.
