FLOOD FREQUENCY ANALYSIS USING GUMBEL’S DISTRIBUTION METHOD: A LOWER DOWNSTREAM OF LOHIT RIVER (DANGORI RIVER), ASSAM (INDIA) Sonowal Gulap Research Scholar, Geography Department, Cotton University, Guwahati, India Thakuriah Gitika Assistant Professor, Geography Department, Cotton University, Guwahati, India ABSTRACT Flood frequency is the most important … However, this study involves the flood frequency analysis of Dudhkumar river for its flashy nature in the recent years (1996-2010) using two methods Gumbel’s and Powell’s respectively. Estimation of Peak Flood Discharge for a desired return period is a pre-requisite for planning, design and management of hydraulic structures like barrages, dams, spillways, bridges etc. 1 0 obj Flood Frequency Analysis is the statistical calculation of the probability of occurrence of flood of specific magnitude in a river, the specific period is called return period and the flow can be ranked as maximum possible flow.

To the best of author’s knowledge, no previous study was done to model dudhkumar’s flashy nature. Gumbel distribution is a statistical method often used for predicting extreme hydrological events such as floods (Zelenhasic, 1970; Haan, 1977; Shaw, 1983).
