Planning of Sectoral Water Allocation: A case study of Seyhan River Basin

Abstract

In this study water allocation plan for Seyhan Basin that is the second largest after the Nile basin located in the eastern Mediterranean was prepared. The purpose of the study is that a plan for water allocation among groups of water use, or sector is developed by considering environmental and socio-economic conditions as well as the potential of surface and groundwater resources. Current (the year 2016) and future conditions (2017, 2022, 2027 and 2037) have been analyzed in terms of economic and environmental aspects. Scenarios on water allocation were created to determine the most suitable water use pattern. The major finding is that water potential is expected to drop to 6.6 billion m3 in mild drought conditions and 6.3 billion m3 in severe drought conditions due to the impacts of climate change. Consequently, agricultural water needs are met in the range of 90% level (the year 2037) to 94% level (the year 2017), and environmental flow needs are met in C level of environmental management class in the context of applied method (GEFC).
