Analysis of Hydrometeorological Characteristics and Water Demand in Semi-Arid Mediterranean Catchments under Water Deficit Conditions

Drought is one of the most complex and poorly understood catastrophes on planet. Between Greek mainland Turkey, there an area Greece known as South Aegean Islands, that experiences water supply issues. As a result, are issues related to socioeconomic growth some these islands, need for transportation by vessels. Water ships Cyclades Dodecanese areas from or other adjacent islands satisfy urgent demands, hand, exceptionally expensive. The situation deteriorates during summer, when drinking needs can reach five times norm, due heavy tourist season. Given conditions, aim this research estimate hydrometeorological calculate balance, determine in three southern (Mykonos, Naxos, Kos), where shortage, particularly summer months tourism activity at its peak. modified Thornthwaite–Mather monthly hydrological balance model was applied balance. Various use datasets (drinking water, irrigation, transportation) were employed quantify demands islands. According results, available (runoff + infiltration) seems be more than sufficient meet Naxos Kos, since it far exceeds increased Yet, appears Mykonos, resources have been nearly entirely utilized, just enough needs. It evident all present significant sources which could growing residents. However, absence necessary exploitation projects, mainly concerning surface runoff, has contributed intense problems importance harvesting projects becomes even under conditions climate change, with decrease annual rainfall likely highly possible scenario, especially arid semi-arid regions.
