Seasonal changes in suspended sediment load in the Gautami-Godavari Estuary

N.P.C. Reddy, B.P. Rao, K.M. Rao, V.S. Rao

Abstract



Studies carried out on suspended matter characteristics of the the Gautami Godavari Estuary revealed that the concentration of suspended matter (CSM) during southwest monsoon influenced mainly by the increased run off at both Neelarevu and Vrudha estuarine mouths. During pre-monsoon and northeast monsoon seasons, the CSM is mainly controlled by the tidal currents (10 cm/s to 150 cm/s) asthe fresh water discharge during this period is minimum. Higher CSM (270 mg/l) at Vrudha estuarine mouth compared to Neelarevu (95 mg/l) estuarine mouth during this period could be due to the turbulence caused by wave action and tides
