Modelling approach for the rainfall erosivity index in sub-humid urban areas in northern Algeria

This work presents an approach for storm water erosivity Tank index modelling in the absence of measurement in an urban area, in a sub-humid climate.In torrential storms, floods, loaded with sediments, obstruct storm water drainage.With the aim of estimating the amount of sediment that can be deposited on a stretch of road, adjacent to the study area, the erosivity index is determined from a count of 744 rain showers recorded over a period of 19 years.The Universal Soil Loss Equation (USLE) of Wischmeier and Smith is applied, where only the index of erosivity is calculated; it is based on the intensity of the rain starting the process of erosion in the basin.Functional relations are required between this factor and the explanatory variables.

A power type regression model bellfordtoysandhobbiers.shop is reached, making it possible to bring a decision-making aid in absences of measurements.
