|Abstract: ||Reservoirs, especially which are formed by dams on natural water courses
are subject to some degree of sediment inflow and deposition. Because of
this, they are exposed to sediment-related problems.
Legedadi, the main water supply resource of Addis Ababa city, is loosing
its capacity due to sedimentation. Bathymetric surveys in 1979 and 1998
have been undertaken to estimate the extent of the sediment in the
reservoir and shows that sediments are accumulating at a rate of
0.11Mm3/year for the intervening period.
This paper presents the attempts made to assess the amount of sediment
inflow and the total quantity which is accommodated to date on Legedadi
reservoir using SWAT watershed and CCHE1D sediment transport models.
These two models were applied to a variety of sediment studies in
different countries like Wyoming East Fork river, Danjangkon reservoir,
Mississippi Goodwin Creek water shade, Taiwan Pa-chang…and a good
agreement between measured and computed yields is illustrated.|
