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).
