Reservoir sedimentation : the case of the Opa Reservoir catchment, southwestern Nigeria

Auteur :
ADEDIJI, A.

Description :
This study aimed at determining the rate of sedimentation in the Opa Reservoir since impoundment in 1978 with a view to ascertaining how much of its volume has been silted up. The study highlights the need for frequent bathymetric surveys, especially after large floods, to provide more information on the magnitude of annual sedimentation, and to help planners determine how to prolong the life of reservoirs. - (AJC)
