| Abstract: | Traditionally, water quality modelling has focused on modelling individual water bodies. However, water quality management
problems must be analyzed at the basin scale. European Water Framework Directive (WFD) requires introducing physical, chemical
and biological aspects into the management of water resources systems. Water quality modelling at a basin scale presents the
advantage of incorporating in a dynamic way the relationships between the different elements and water bodies. Currently,
there are few tools to deal with water modelling of water quality and management at the basin scale. This paper presents the
development of a water quantity model and a water quality model for a very complex water resources system: the Júcar River
Basin (Spain). The basin is characterized by a high degree of use of the water and by many water problems related to point
and diffuse pollution, on top of a complex water quantity management of the basin. To deal with this problem, SIMGES (water
allocation) and GESCAL (water quality) basin scale models have been used. Both are part of the Decision Support System AQUATOOL,
one of the main instruments used in Spain in order to analyze water quantity and quality aspects of water resources systems
for the compliance with WFD, as shown for the case of study. |
