The BVH (Bassin Versants de Haïti, Watersheds of Haiti) research project aims at providing a reliable estimation of the water resource in Haiti. Firstly, we used an automatic extraction from Digital Elevation Model (DEM) to describe the main watershed components: drainage networks and watershed boundaries. Secondly, we provide a detailed analysis of the hydrographical reference system (spatial and geophysics) on Haiti. We studied in depth the main watershed components, calculating altimetry parameters (linked with relief), hydrographic parameters (the 2D drainage network) and periphery parameters (the shape of their boundaries). An open source software have been developed to compute and spatially analyze hydrographic parameters. A quick presentation of this software and its features will be shown during the presentation. The analysis covers the four fifth of the total surface of Haiti and concerns the principal watersheds. Our main result is a four clusters classification, each cluster having well defined and interpreted geophysical properties.
