This paper presents an alternative commonly used techniques for hydrograph recession analysis, namely of an individual recession segment, the master recession and a relatively recent approach based on wavelet transform was carried out in order to separate analytically the linear component hydrographs by recession index K that is commonly used as an indicator of flow. These methods were applied to a set of measures hydrometric the North-eastern Algeria in the watershed Seybouse. The results show that all the methods tested produce reasonable and comparable results.
