Typical Case Studies
Few large scale wave models, domains spreading to several thousands of square kilometres, are developed for specific conditions. To mention a few, wave model for the entire Bay of Bengal has been developed, using advanced WAVEWATCH III numerical scheme, which gives the estimate of wave characteristics all along East coast of India, with offshore winds as input.
In addition, a unique & dedicated wave-tide coupled model has been developed, exclusively for Gulf of Khambhat, where the tidal dynamics and predominant and influence the wave characteristics.
The results of in-house developed large scale wave models are validated with many in-situ data buoy measurements, thanks to the data provided by various Indian research institutions (INCOIS, NIOT, NIO).
Several regional scale wave models, spatial domains of few hundred square kilometres, are developed with input either from large scale models and or from global models. These models are developed using either WAVEWATCH III or SWAN, depending up on the domain requirements. To name a few, specific wave models have been developed for selected coasts of India (Pondicherry, Andhra Pradhesh, Maharashtra, South Gujarat, Goa), Kuwait, AbuDhabi, Bahrain, SriLanka and various other regions of globe.
These regional scale models are usually developed, based on the requirement to represent the regional conditions and are validated with field measurements, as available.
