Abstract :
    Abstract News about droughts and dehydration, as well as the construction of undeveloped dams that expose more water to volatile water, conserves water resources in new ways. Agricultural, urban, and industrial areas require new approaches to water conservation. Due to the very high soil erosion rate in the country as well as the need to construct dams in order to contain floods, there is a great deal of damage to the environment and rangelands. Water that is very expensive and damaging to rangelands and submerged areas should be used to the maximum. Providing a method that can provide an accurate and relatively accurate prediction of reservoir evaporation and precipitation can be important in identifying the need for future developments including water resources management and conservation. Time series are a priority as a suitable tool for predicting tank evaporation and water resources management. The use of time series is nowadays a useful tool for various forecasts. In this study, 34 year data of two synoptic stations of Saveh and Shah Abbasi Dam were used to model evaporation values of free water west of Saveh Dam and by conducting necessary investigations on these data and by using time series software Different models were evaluated using different tests and selected models were introduced for the stations. Two methods for reducing water evaporation of Saveh Dam reservoir were also evaluated. The results showed that the two methods of using black plastic balls and liquefied liquids are effective in reducing the evaporation of dam water, but due to time series it is not possible to choose the most suitable model from these two methods and the present study with evaporation prediction Use of station time data is provided. In other words, the results of the previous season tests showed that these two methods are effective in reducing evaporation.
