Abstract EN

The research aims to find the relationship between the amounts of rainfall and its impact on the water resource values of Lake Hamrin for the period (1990-2019).

The results showed that rain is one of the most important factors affecting the water resource values.

For dams and lakes built on them, and the discrepancy in the strength of the relationship between the amount of rain falling and the water supplies in the lake depends on the amount of rain falling during the year, but the presence of more than one water dam on the same river that affects the level of its water storage.

Therefore, the effect varied and the strength of its relationship differed from year to year, so a strong relationship appeared in the rainy seasons, as the first period (1990-2000) and the third period (2010-2019) recorded a correlation between the amount of rain and the values of the lake's water, which amounted to (0.89 and 0.84) on the respectively, which is a strong relationship with a significance value of, while the relationship is ent in the dry seasons, as the period (2000-2010) recorded a weak relationship of (-0.04).
