| description | Recently, the Kessem–Tendaho project is completed to bring about
socioeconomic development and growth in the Awash River Basin, Ethiopia. To
support reservoir Koka, two new reservoirs where built together with
extensive infrastructure for new irrigation projects. For best possible
socioeconomic benefits under conflicting management goals, like energy
production at three hydropower stations and basin wide water supply at
various sites, an integrated reservoir system management is required. To
satisfy the multi-purpose nature of the reservoir system, multi-objective
parameterization-simulation-optimization model is applied. Different
Pareto-optimal trade-off solutions between water supply and hydro-power
generation are provided for two scenarios (i) recent conditions and
(ii) future planned increases for Tendaho and Upper Awash Irrigation
projects. Reservoir performance is further assessed under (i) rule curves
with a high degree of freedom – this allows for best performance, but may
result in rules curves to variable for real word operation and (ii) smooth
rule curves, obtained by artificial neuronal networks. The results show no
performance penalty for smooth rule curves under future conditions but a
notable penalty under recent conditions. |
