Bathymetric Survey for Enhancing the Volumetric Capacity of Tagwai Dam in Nigeria via Leapfrogging Approach

From a global perspective, dams are constructed to trap water flowing from higher concentration lower into basin for several purposes aid humanity. The continuous monitoring of is prudent measuring the rate sedimentation and siltation, ensure that it functions its full capacity. Tagwai dam used irrigation domestic activities. It was observed there shortage in storage capacity supplies due sedimentation, coupled with this fact majority communities not connected tap system; if not, problem would have been evidently pronounced. However, determine present volume provide possible ways increasing reservoir’s capacity, leapfrogging approach improve basin. data were collected using single beam echosounder Hi-Target V30 differential positioning system (DGPS). sounder acquire bathymetric data, while DGPS delineate shoreline. interpolated ordinary Kriging technique. After that, method grouped four scenarios: Scenario A, B, C, D. In each stage, computed Simpson’s 3/8 integrated model. A stage reservoir. Consequently, results show scenario B C presented an appreciable increase at instant, D illustrated tremendous improvement win-win situation. decision on which employ depends government’s willingness enhance resources available, such as human financial capital execute project.
