An investigation of water potential of lakes district, Turkey

Abstract

Recent increase in urban population, water pollution due to industrialization, and climate changes revealed the need to revisit water utilization policies, to use water resources adequately, redo critical analysis for existing prevention plans and prepare new prevention plans. In the present study, current state of the water potentials of Eğirdir, Kovada regions, located at lakes region, are investigated in terms of precipitation, temperature, evaporation, and water level change by using the monthly and annual data available. Therefore, the data is processed by using Run homogeneity test, Mann Kendall and Sen analysis. In addition, water budget analysis is carried out for Lake Eğirdir. It is found that analysis results and water budget results overlap for Lake Eğirdir. Provided that, preventive measures are not taken immediately, at the end of a 100- year period. Level of Lake Eğirdir is estimated to decrease 24-%, annually. To prevent the water level decrease in Lake Eğirdir, there are some necessary precautions should be taken-: (a) Inactive underground resources should be activated,-. (b) Irrigation lands which use water from Lake Eğirdir should not be allowed,-. (c) Future water storage within the rainfall watershed should be prevented,-. (d) The lands that have shown no signs of development and expected not to improve in the future should be detected and these lands should be removed from future irrigation plans,-. (e) Efficient methods of economical use of water resources for the currently cultivated irrigated lands should be explored and developed,-. (f) Throughout the use of intelligent farming methods economic utilization of water should be performed. Concurrently, there will be effects on Lake Kovada since Lake Kovada is controlled by Lake Eğirdir through a water channel.
