Abstract

The rule curves developed for a specific reservoir are used to evaluate the performance of the reservoir within a year and compare to the forecast performance by using inflow and benefit summation curves. The range of annual benefit from lower values in dry years and higher values in wet years is obtained under certain risk conditions. The 32-year period of reservoir routing indicates that the boundaries of annual benefit may be higher or lower expressed as positive or negative quantities added to the annual benefit. It is proven that the realised reservoir level variation followed the forecast one from August to November, and from April to July. Due to several reasons the reservoir was lowered from December to March, indicating an extremely intense lowering. High
