Evaluation of the effects of run off water on the Founkama plain in the Urban commune of Faranah, Republic of Guinea

This research aims to assess the effects of runoff water on flood basins and structures. To achieve this, we identified the decomposable and non-decomposable materials that ran off the flood basins and into the canals; the effects of runoff on the flood basins; Quantify the volumes of soil transported by runoff on the north and south sides of the said plain; The research work took place from January 2 to October 31, 2014 inclusive. The results obtained are as follows: The area occupied by non-decomposable materials in sample per m2 is: 106.74; the average weight of the samples is 4.6 kg; the height of earth transported in layers in the submersion basins in cm is: the North side 60, the South side 47.5 and in the central canal 58.6; the volume of earth transported in the canals in m3 is: in the North belt canal 224.4 in the South belt canal 89.25 and in the central canal 599.4; the influx of earth deposits by runoff water in the belt canals in cm is: South 58.188 and North 45.278.
