Optimum operation of al-Adhaim dam for selected periods of time

Abstract EN

In this research, the discrete differential dynamic programming approach is used to find the optimal monthly operation of Al-Adhaim Dam by adopting an objective function to minimize the release and storage penalty.

The historical inflow data of (852) months (from Oct.

1937 to Sep.

2007) formed the input data to the optimization model to find the (upper, average and lower) rule curves.

The optimization model is applied to two hypothetical operation that represent the extreme cases, namely, three consecutive relatively-wet years and three consecutive relatively-dry years.

Preserved the logical state of reserve storage, i.e., save minimum operation storage just before the expected start of the effective flood and maximum operation storage at the end of the flood season.

The optimum operation policy has shown deficit in satisfying the demands downstream Al-Adhaim Dam.

The deficiency was noticed during (15) months in wet three years and (24) months in dry three years.
