Planning, Analysis and Design of Vented Drainage Canal Across River Ganga in Falta, West Bengal

Water is transported through vented drainage canals. The vents control the water to stop too much water from entering the fields. Ventilated drainage canal shapes influence the speed and amount of water flowing through the tunnel. By maintaining proper water velocity, the trapezoidal shape prevents silting and scouring. Due to the high erosion zone and low soil-bearing capacity, pile foundations are used here. The site chosen for this consideration is Falta, West Bengal, across the Ganga. A site plan for the vented drainage canal has been prepared using AutoCAD 2020. An analysis of the canal has been performed using STAAD.Pro software. To calculate the critical time for the work, a schedule was prepared. A detailed cost estimation was performed as well as a cost-benefit analysis. As part of the project, piles, pile caps, vented drainage canals and deck slabs were constructed, and a 3D model was created for the vented drainage canal.
