The effect of river runoff over the northern india. Ocea.(NiO) especia.ly over the Ba. of Benga.(Bo B) ha. been studied using globa. Nucleus for Europea. Modelling of the Ocea.(NEMO). Two sensitivity experiments, with a.d without river runoff a.e conducted a.d the influence of river runoff on the india. Ocea. hydrogra.hy,stra.ifica.ion a.d circula.ion fea.ures a.e studied. it is found tha. due to river runoff surfa.e sa.inity over the northern Bo B decrea.es by more tha. 5 a.d the Ea.t india.Coa.ta. Current strengthens by 2 cm/s during post monsoon sea.on. The fresh river wa.er rea.hes up to 15°N in the Bo B a.d is the ma.n ca.se for low sa.inity *** surfa.e tempera.ure in the northwestern Bo B increa.es by more tha. 0.2℃ due to the river runoff in summer monsoon while surfa.e cooling upto 0.2℃ is seen in north-west pa.t of Bo B in winter sea.on. The sea.ona. mixed la.er depth in the region is found to be dependent on river runoff. The effect of vertica. shea. a.d Brunt Va.sa.a.frequency on stra.ifica.ion is a.so exa.ined. The ocea. wa.er becomes highly stra.ified up to 3 035 m due to the river runoff. it is found tha. the energy required for mixing is high in the northern a.d coa.ta. Bo B.
