Abstract: Extreme environmental events such as floods cause a lot of damage to life and property of human society. A reliable estimation of magnitude and frequency of occurrence of such extreme events is of great significance in minimizing damages by facilitating proper planning and design of civil engineering structures such as bridges, barrages and dams. In the present study, the L-moments have been used for flood frequency modelling of Beas basin. River Beas, which is an important river of Indus river system, has been selected for the study. The Beas basin is frequently affected by flash floods in the main river and its tributaries. Annual flood series of 20 years or so of eight sites in the basin have been used for the study. The homogeneity has been verified using tests based on L-moments. The EV-I, generalised extreme value (GEV), logistic, generalised logistic, generalised pareto, normal and lognormal distributions have been applied for flood frequency modelling. From the goodness of fit tests based on L-moments coupled with simulations, it has been found that the GEV distribution can be used for estimation of probable floods for Beas basin.
