Abstract

Extreme hydrological events, such as floods and droughts, are one of the natural disasters that occur in several parts of the world. They are regarded as being the most costly natural risks in terms of the disastrous consequences in human lives and in property damages. The main objective of the present study is to estimate flood events of Abiod wadi at given return periods at the gauge station of M'chouneche, located closely to the city of Biskra in a semiarid region of southern east of Algeria. This is a problematic issue in several ways, because of the existence of a dam to the downstream, including the field of the sedimentation and the water leaks through the dam during floods. The considered data series is new. A complete frequency analysis is performed on a series of observed daily average discharges, including classical statistical tools as well as recent techniques. The obtained results show that the generalized Pareto distribution (GPD), for which the parameters were estimated by the maximum likelihood (ML) method, describes the analyzed series better. This study also indicates to the decision-makers the importance to continue monitoring data at this station.
