أثر بعض العناصر المناخية في تغير قيم الوارد المائي لبحيرة سد العظيم

Abstract EN

The climate with its various elements is the factor that affects water resources, whether surface or groundwater.

As any change in the values of climatic elements will have an impact on water income negatively or positively, and the dams and lakes on which they were built on are one of the means of water storage, collecting, and employing it in various areas of irrigation and generating electricity.

The amount of existing water in these reservoirs is subjected to change in their quantities as they may be reduced to the lowest level affected by climatic changes taking place in the region.

This research to identify the amount of affect that climatic elements make on the water income values of Al-Atham Dam Lake, by knowing which climatic stations and any of the climatic elements are more influential on the values of the water income.

To reach the aims of the research the researchers relied on the data of the water income of Al-Atham Dam Lake for a period of (2001-2017), as well as, on three climate stations, TuzKhurmatu, Kirkuk and Sulaimaniyah, and climatic elements (amount of temperature degrees, amount of rain, evaporation and wind speed).

The analysis of multiple versions was the statistical method used in the research, as it was found that the strength of the influence of climatic elements on the values of water income varied.

The rainfall was the dominant element during the winter, while temperature, evaporation and wind speed overlapped as influential factors during other seasons, and found that Sulaimaniyah station was the most influential station on water income of the lake.
