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 … In this study it has been applied for flood frequency analysis because (a) peak flow data are homogeneous and … To the best of author’s knowledge, no previous study was done to model dudhkumar’s flashy nature. This Flood Frequency Analysis study is relied upon 21 years (1998-2018) tributary inflow measurements at Komani lake. 2 0 obj Duration (D) of Unit-Hydrograph and Peak Discharge (Q p ) .vs. %PDF-1.5 x��=�v�F��9���Gh�E�o@#㣳�/3���$Vv�_ܮ7���}��/�]=4��k֫����������7/���:��� K2��%���':�',�]>�&K��?�}�1��ťH��c*��H����ݢkf�E�l��fѬ..yJ��'���Y=�fU�mc>'�M U:�� Gumbel distribution is a statistical method often used for predicting extreme hydrological events such as floods (Zelenhasic, 1970; Haan, 1977; Shaw, 1983). INTRODUCTION Flood estimation is one of the major aspects of hydrologic design and is the first step in planning for flood regulation and protection measures.

Return Period (T) at Galudhi Dam Site and Kharkai Barrage Site, India, Institute of Landscape, Ecology & Ekistics. The Gumbel’s distribution method which is one of the probability distribution methods used to estimate return period of annual maximum flow stream. 1 0 obj 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. So, the flood frequency analysis is carried out of the Dangori River which is a part of the It was 4 0 obj stream <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 7 0 R 19 0 R 20 0 R 21 0 R 22 0 R] /MediaBox[ 0 0 595.38 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> In this paper, a mathematical model has been developed between Peak Flood Discharge and Return Period using Gumbel’s Extreme Value Distribution. Thus, Gumbel’s method has been simplified in such a predictive model that one can obtain the magnitude of a given return period for flood discharges without recourse to looking at a table. Flood frequency is the most important statistical techniques in understanding the nature of the flood and magnitude of the high discharge in a river. endobj Return Period (T) at Galudhi Dam Site and Kharkai Barrage Site, Development of Hydrological Models between Peak Discharge (Qp) .vs. method (Gumbel, 1958). 3 0 obj endobj endobj Flood Frequency Analysis - Gumbel Method.
