Description 1247-1252
In
Chilka lake a new inlet was formed due to natural coastal processes at
Gabakunda in August 2008 at 1 km north of the existing inlet at Sipakuda.
Present study deals with 2-D mathematical model (MIKE21) studies with two
inlets to assess the hydrodynamic changes and salinity variations due to the
formation of new inlet at Chilika lake. Predicted tide, monthly average inflows
of the rivers and observed salinity are used for the model studies with a
constant width of inlets throughout the simulation period. Newly formed inlet has a dominant role in
contributing tidal exchanges over Sipakuda inlet. Decrease in tidal prism with
two inlets is observed in comparison with that of single inlet system at
Sipakuda, which leads to decrease in salinity of about 10 ppt in all the
sectors of the lake. Lake salinity is improved by preserving tidal exchange
by maintaining the cross sectional area and depth of the inlets.
