In-Depth Information
It was noted that the reservoir routing model produced very good results
in simulating Lake Albert's behavior in attenuating flood peaks for the
maximum, minimum and the average flows. The channel routing model,
however, produced reasonable results in simulating Lake Albert's behavior
for an average year. The results obtained from the process of delineation
though acceptable, would have been more elaborate if an explicit and con-
sistent empirical relationship had been established between the maximum
effective inflows and the respective water levels at Butiaba. This would then
cater for the variation in the cross-sectional area of the storage volume as
the depth/water level of the lake increases in the computation of water
levels of the lake.
5. Conclusions and Recommendations
Flooding in Lake Albert has been successfully modeled using both the fre-
quency analysis and flood routing techniques.
The results from frequency analysis have been used to understand the
behavior of the lake to develop flood demarcation zones in the flood plain.
The reservoir routing model developed, provides a simple and accurate tool
for flood forecasting.
The recommended measures for flood mitigation include establishing of
an early warning system, sensitization of the local inhabitants, develop-
ment of a land management policy establishment of a flood defences and
installation of more automatic gauging stations.
