Simulation of Sediment Deposit and Maintenance Requirements for Sani- Abacha Road Culvert, Rivers State, Nigeria
Abstract: Empirical model of sediment yield equation was applied to develop the sediment deposit monitoring equation of the Sani-Abacha road culvert. The culverts were selected based on field observation of continuous overflow, road overtopping and channel contraction in the course of heavy storm due to sediment built up within and inside the culvert barrel. The result of the assessment shows that the way sediment load varies with discharge is consistent and …

Artificial Neural Network Model to Predict Reservoir Storage
Abstract: The rapid growth in population increases water demand thus resulting in scarcity of water which is due to improper management rather than lack of resources. Reservoir is the most important source for surface water. So, reservoir storage plays a crucial role in efficient reservoir management. Artificial neural network (ANN) is capable of simulating reservoir storage capacity. So, in present work cascade forward back propagation and feed forward back propagation network …

Estimation and Comparison of Depth of Scouring Around Straight Partially Submerged Impermeable Groynes Aligned at Different Angles
Abstract: Groynes are the part of river training structures which are constructed to reduce the sediment load, protection of the banks from erosion and deflect the flow of river in a determined direction to avoid the meandering of the rivers. While protecting the banks of river from erosion, the foundation of the groynes experience severe scouring that leads to the structural collapse of the groynes which may results in loss of …
