The construction of hydraulic structures on watercourses modifies the flow conditions and the extent of flood propagation zones.

This study used hydrometric data, satellite images and cartographic data to design a run-of-river dam and model its influence on the propagation of floods from the Davo River to the drinking water production station in Gueyo (Côte d'Ivoire). The dimensioning of the weir gave the following main characteristics: 2.5 m heigth, 1.3 m wide at the crest, 3.8 m right-of-way and 177 m long. The retention created by the presence of this weir answer the population's water needs, which are estimated at 0.19 m3/s, or 16,800 m3/day. Simulation of the behaviour of the Davo River during high water periods shows that the presence of the weir does not have a significant impact on the extent of the floodplain area.

Abstract
The construction of hydraulic structures on watercourses modifies the flow conditions and the extent of flood propagation zones. To do this, the installation of the structures must be preceded by models ensuring the correct dimensioning of the structures and their influence on the hydrological functioning of the watercourse. This study used hydrometric data, satellite images and cartographic data to design a run-of-river dam and model its influence on the propagation of floods from the Davo River to the drinking water production station in Gueyo (Côte d'Ivoire). The dimensioning of the weir gave the following main characteristics: 2.5 m heigth, 1.3 m wide at the crest, 3.8 m right-of-way and 177 m long. The retention created by the presence of this weir answer the population's water needs, which are estimated at 0.19 m3/s, or 16,800 m3/day. Simulation of the behaviour of the Davo River during high water periods shows that the presence of the weir does not have a significant impact on the extent of the floodplain area.
