SILTATION AND IMPACTS ON THE DENSU RIVER AT ANO AS WATER FLOWS FROM THE DAM TO WEIJA IN THE GREATER ACCRA REGION OF GHANA.
Siltation by soil erosion and runoffs carrying varied amounts of residues has both positive and negative impacts on the Densu Ano River. The sediment has reduced the total capacity of the River both at the upstream and downstream face and therefore posing threats to the future and survival of the River. Different kinds of technologies such as bioengineering has been employed to work on the banks of the River in order to avoid this eventuality. This research work looks at siltation impact on the Densu River at Ano Community as it flows through the natural channel from the Ano community to Weija. The work establishes that, sedimentation has reduced the total capacity of the River and having effect on total volume of water in the river and on abstraction rate for water treatment and distribution. Farmers and people within the communities are adhering to the 20m buffer zone policy administered by the Water Resource Commission to protect the resource for the future.
