The use of Geographic Information System (GIS) models for water quantity and quality modelling is indispensable for the determination of impacts of land-use or climate changes that are expected to take place. Southern Ukraine today suffers from severe droughts, floods and soil salinisation. It is therefore of utmost importance to use the available water resources optimally and to avoid loads from coastal waters. The paper reports the results of studies that were carried out in three pilot areas in Crimea, including the catchments of the Salgir and Pobednaya rivers. The main problems of the Upper Salgir sub-basin are related to erosion and urbanisation impacts. The transfer zone and coastal areas are subject to intensive restructuring and agricultural development, including the reconstruction and reorganisation of irrigation systems. The River Pobednaya drains a coastal area in the north-east of Crimea. Here, irrigation and drainage and in addition waste water discharges are having impacts on the Sivash Wetlands that increasingly cover the coastal area of the Sea of Azov. In order to solve all these problems, regional stakeholders have been invited to develop scenarios that are further evaluated by modelling exercises. © 2011 John Wiley & Sons, Ltd.
