INTRODUCTION There is growing evidence for changes in the global hydrological cycle over the past decades that may be linked to changes in climate (CC). In 4.2. Activity: Present and future risks on water resources availability with emphasis on drinking water supply common methodology for determining available water resources was agreed, taking into account different resources types and water intake for public water supply, different manifestations of climate impacts, different sizes of analyzed test areas, as well as different levels of data availability for describing current state of water resources and forecasting possible changes. On figure 1.1. the relation between activities within work package 4 (WP4) and also outputs are presented. Figure 1.1: WP4 activities and outputs Common methodology for determination of water availability in Adriatic area – July, 2016 6 In the Adriatic area 9 test areas were selected (figure 1.2) to analyse the risk on water resources availability in the future 2021-2050 period under the climate change impact, where as a criterion for consideration of climate change impact standard climatological 30- year period 1961-1990 was selected as reference. The availability of water resources was analysed from the aspect of total use and use for drinking purpose. Water resources in test areas have cross-border or cross-regional character and their availability can affect the water supply in more than one country or region within the country. On figure 1.3, test area locations are shown with marked meteorological stations whose data are included on figures 1.4 and 1.5.
