ABSTRACT: The hydrologic and hydraulic changings on the
behavior of Mono river are the result of the stress involved by human
activities, on one hand and the construction of the dam of Nangbéto and the
exploitation of sand in downstream of the dam by the population, between
Athiémé and Agbanankin on other hand. That effect had also affected the shape
of the sections of the river in the context of climate variability. It shows
consequently that area is also a trapping area of sediments eroded in downstream
of the dam and is responsible for the trapping of sediments in the river. The
slope and the flow rate are the main factors of the real capacity of transport
of a watercourse. They also determine the transport of solid flows from
upstream to downstream. This drawing model established by taking into account
the bathymetry of a transversal section of the Mono river at Athiémé, is the
first step of a global investigation of the solid flow transport in the basin
of Mono river and the boundary condition for the characterization of its
hydro-sedimentary dynamics study. It aims to take into account sections and the
used technique which consist to measure on one located section as the
representative section of the river at Athiémé, by moving the boat used for bathymetry.
