Study on 1D-2D Hydraulic Modeling of a Diversion Channel on the Cavally River in Zouan-Hounien, Cote d’Ivoire

February 1, 2021 Environment and Earth Science 0

In recent years, many hydraulic infrastructure, such as bridges and drainage channels, are expected to be constructed on the Cavally River, situated on the border between Côte d’Ivoire and Liberia, on the operational perimeter of the mining company Ity. In order to ensure hydraulic activity close to the initial conditions of the river, a 1D-2D hydraulic model was built to construct a diversion channel to cut a meander from the Cavally River (water levels, flow and velocities). With a flow rate of 240 m3/s and a Manning coefficient of 0.052 m1/3.s-1 for the minor bed and 0.06 m1/3.s-1 for the main bed, this model was built. The results from the hydraulic model indicate that the hydraulic conditions in the channel before and after the diversion remain much like those of the Cavally River (water levels, velocities). Flow velocities range from 0.1 to 1.6 m/s from upstream to downstream in the Cavally Channel. Hydraulic conditions in the channel after diversion (water levels, flow and velocity) would remain substantially like the watercourse’s natural state. Therefore, the diversion channel would have no major effect on the Cavally River’s hydraulic activity.
