An Analysis of Hydrographs of the Brahmaputra River at the Gauge Site of Goalpara, Assam

A hydrograph generally refers to a graph that shows flow characteristics of river water in respect to time. It is generally used for studying the hydrological characteristics of a river such as variations in water level, volume, discharge etc. with time. In the present study an analysis of the hydrographs of The Brahmaputra River has been made using its monsoonal stage discharge recorded at the gauge station of Goalpara. The data have been collected from Water Resources Department, Chandmari, Guwahati-3, Assam. The analysis has been done based on the water level or stage (maximum, minimum and danger level). The maximum water level is found in 2002 in the month of July (37.12m) which has crossed the danger level (36.27m), while the minimum water level is found in 2014 in the month of May (31.15m
