ABSTRACT
The goal of current paper is to follow the circulation pattern in lake Rudrasagar occurring during episodes of significant wind flow. An early established wind induced three dimensional lake circulation numerical models developed by Cocyigit and Falconer in the year 2004 has been applied to this lake,where a conventional sigma co-ordinate system was applied for following the bathymetry of the lake more accurately. This model was already tested against analytical solution and laboratory data and was successfully applied to Esthwaite Water, a small lake in Cumbria by the model designers. Application of this model in the lake Rudrasagar, West Tripura reveals some typical circulation patterns for different conditions. Numerical results were compared with measured velocity profile of the lake and the study reveals a fair agreement between them. Changes in the magnitude of velocity were also estimated along and across the wind axis for this lake and were found to be insignificant.
