Abstract: The vulnerability of riverine populations confronted to rivers floods and the socioeconomic consequences of floods remain a major concern for the Haitian public decision-makers. However, the use of modelling tools for flood prediction and mitigation purposes is not yet well established in the country. This paper presents the first results of an ongoing study on the Cavaillon River in Southern Haiti, with the aim of constructing a methodology to design a suitable model for the river and to run flood scenarios. First, old topographic data were combined with new data obtained from field measurements to construct the hydraulic model. The roughness parameter in this model was calibrated using the scarce available water level and discharge measurements. On this basis, flood scenarios were run using an estimate of the 100-year discharge available from previous studies. Then, an adapted procedure to construct flood maps is presented.
