Study the effect of evaporation on water quality to the Iraq reservoirs

الملخص EN

Water budget is a basic tool that can be used to evaluate the occurrence and movement of water through natural environment.A water budget provides a foundation for evaluating its use in relationship to other important influencing conditions such as other ecological systems and features, as well as social and economic components; how much water is being used by industry, residents, etc.

The main research methodology is to find area elevation curves of the reservoirs, monthly evaporation losses from the reservoirs with different conditions of storage, the amount of increase in the salinity of the water due to evaporation and its relationship with the volume of storage, the results analyzed and discussion.

The study presents an estimation of to the amount of water loss due to evaporation from some Iraqi reservoirs and its effect on the water quality.

This paper studies the effect of storage in water losses due to evaporation of reservoirs, lakes and marshes in Iraq with different conditions of storage (minimum, average and maximum).

Q-Basic program uses to find the results.

Results show that losses caused by evaporation reaches about (22 %) from storage volume at average condition, where the Total Dissolved Salts is increase to about 17 % at the same condition.
