Abstract
Ikpoba Dam serves a singular purpose - the provision of potable water to the populace of Benin City. However, the dam's functionality has been adversely affected by acute sedimentation. In response, comprehensive bathymetric surveys were conducted to assess the volume of sediment accumulated during its operational period. This study delves into a thorough investigation
employing a longitudinal profiling technique for short-term mapping of Ikpoba Dam's bottom topography. The primary objectives encompass determining short-term variations in the longitudinal profile of the dam's bottom, generating short-term Digital Terrain Models (DTMs) of the dam's bottom topography, and calculating the accumulated sediment volume by everaging Digital Elevation Models (DEMs) differencing.
