Özet (Çeviri)
The controlling of part of vast quantities of water that have been evaporated is a proper mean of providing adequate water supplies. The monolayer (film) technique is used in order to cut down the rate of evaporation without any serious effect to the water quality and to the human health. However, a lot of methods can be used to retard the evaporation but because of technical and economical feasibility, not all of them can be used everywhere. The purpose of the thesis is to investigate the possibility of applying the monolayer film technique on Istanbul water storages and determine the effect of these methods on water quality and on environment. Moreover, this study aims to determine an appropriate model for computing rate of evaporation from Istanbul. Furthermore, this study was conducted at Kaoithane (near pipli) on two tanks, one of which was treated with a monolayer and another left un-treated for comparison. The use of chemical methods (i, e. mechanical oil) and physical method (i, e. floating cover from ping pong balls), indicated that, floating cover represented a good result even though the chemical method may save the evaporated water by more than 90 per cent, but these chemicals may create environmental pollution when the film is removed by the wind action. In addition, in the last few years the drought conditions facing Istanbul has resulted into an increase in evaporated water, this makes the application of the monolayer technique to be very important in providing a reliable water supply. About 62 million cubic meters of water was evaporated from Istanbul during 1994 .
