Abstract

This study is a new application of the recession curve analysis with a new non-subjective method. Its objective is to construct master recession curves generated by placing, horizontally, the vertex of individual recession segments of the most suitable connection line defined by measurement points of a preceding recession segment. This proposed methodology was applied for a rural catchment with a low urban contribution, namely Madjez Ressoul, which is located in the Ain Berda region in Algeria. The results of separation always give an appropriate R2 coefficient; they confirm the ability to calculate the recession curve coefficient k of the three processes (surface flow, subsurface flow and baseflow).
