Modeling the Evolution of Solid Flows Rate Based On Rainfall of the Mewou River in the Mifi Basin (Published)
The objective of this study is to evaluate and model the solid rates based on rainfall over the Mewou River, in the Mifi watershed. We have determined in the specialized laboratories the quantities of solid exported from the samples taken from this watercourse. The MATLAB software allowed us to simulate the evolution of solids discharge based on rainfall over this stream. This evolution is characterized by the polynomial equation of the eight degree with a correlation coefficient of 0.9999 and a coefficient of determination of 0.9998: Qs = a*p8_+ b*p7 + c*p 6+ d*p5+ e*p4 + f* p3 + g* p2 + h* p + i. This model is more interesting than the polynomial model of degree two (Qs = a* p 2 + b* p + c) and the power model (Qs = a*pb) developed by other authors.
