CHESS : Climate,hydrochemistry and economics of surface water systems

The CHESS project has as its overall objective to investigate how expected
changes in climate will affect the quality of freshwater resources in
Europe.
To achieve this, a common modelling framework is developed, comprising
catchment and river models of water quantity and quality and that
incorporates pollution from diffuse sources(e.g. agricultural) and point
sources (e.g. industrial and urban effluents). Simulators used in this
framework are SWAT (USDA) and Questor (Institute of Hydrology).
The models are being validated against a set of study catchments in five
European countries for the present day conditions.
For future conditions, different scenarios are considered, based on
different global circulation models.
