Hydromorphological developments and risks in Atakpamé (Togo)

This book has three objectives: to identify the causes of the accelerated morphodynamics of the Atakpamé site; to identify and explain the hydromorphological risks that surface mechanisms generate; and to propose guidelines for better management of the Atakpamé urban area. To achieve these objectives, our methodology was based on fieldwork and mapping. The fieldwork involved numerous observations and measurements of surface mechanisms, as well as interviews with resource persons. Mapping was based on 1:50,000 topographic maps, interpretation of 1:30,000 aerial photographs and field data. Analysis of the results shows that the surface mechanisms that generate hydromorphological risks are erosion, flooding and landslides. These surface mechanisms are set in motion by human action in a physical context that is conducive to their occurrence. Reducing the effects of hydromorphological hazards in this town requires a participatory approach as part of a forward-looking urban development plan.
