The best fit equations for the storage-elevation and water surface area-elevation data of reservoirs

الملخص EN

In this research, the shifted power equation y = a (x-b)c, is proposed to best fit both the storage-elevation and the water surface area-elevation data of reservoirs.

This equation is tested through two examples : Bastora reservoir and Al-Adheem reservoir, and compared with other possible best fit equations.

It is concluded that the shifted power equation is the best one, and thus it can be adopted to represent the best fit equation for both the storage-elevation and the water surface area- elevation data of reservoirs.
