| Zusammenfassung |
| Runoff could be a quick response of river basins to climate change. Drought events in
some selected sub-catchments of the Volta basin in West Africa were analyzed to detect
if any, the effects of climate variations on runoff regimes especially during low flows in
the last decades. Statistically, significant changes have been realized in the last centaury
(Oguntunde et al, 2006). As the hydrological conditions in the Volta have not been
favourable in the last decade, it has become necessary that attention is given to water
management strategies as problems may arise if this situation continues or shifts into
more water stress conditions predicted by the climate model ensemble used by IPCC
(2007) for the region. If there is a general concession that hydrological conditions across
the world is changing, then concepts on water management need to fit the changing
situations. The growing number of reservoirs in the basin would need improved and
flexible methods of reservoir operations. One concept based on the application of fuzzy
sets for estimation of adjusted real-time reservoir operation is presented. |
