Summary

The Keritis river basin is considered to be the most important hydrological catchment in the peculiarity of Chania. A hydrological and geochemical simulation was performed, using the modified SWAT-KARST model, to assess the hydrological budget of the watershed as well as its quantitative and qualitative change in the following years. Also the impact and temporalvariability of management practices and agricultural and livestock loads to the quality of groundwater and surface water were estimated. Data from three regional climate models for the A1B emission scenario were used in this research to study the impact of climate change in the water resources of the watershed till the end of the 21st century. Simulations resultssuggest a drastic decrease in precipitation (30%), karstic spring discharge (30% - 40%) and surface runoff (70%). Also, a further quality downgrading is expected in groundwater and surface water. This study is expected to be used as a useful tool for decision makers of the area with the purpose of developing a strategy for an integrated water resource managementfor the Keritis river basin.
