Abstract:
It became so usual for the east coast of India to face at least IO to 15 cyclones every year, out of which 3 to 4 may reach the deep depression stage. As a result the east coast of India experiences frequent heavy damages of varying intensities due to storm surges and it is also not unusual to experience a calamitous deluge once in a decade or so. Loss of life and damages can be minimized only if the magnitude of the surge could be predicted at least a day in advance. Therefore, an attempt to study the storm surges generated by the cyclones that strike the
east coast of India and. suggest a method of predicting them through nomogram is made

Abstract:
Of the several physical processes occurring in the sea, vertical motions have special significance
because of their marked effects on the oceanic environment. upwelling is the process in the sea
whereby subsurface layers move up towards the surface. The reverse process of surface water sinking to subsurface depths is called sinking. Upwelling is a very conspicuous feature along the west coasts of continents and equatorial regions, though upwelling also occurs along certain east coasts of continents and other regions, The Thesis is an outcome of some investigations
carried out by the author on upwelling and sinking off the west and east coasts of India. The aim of the study is to find out the actual period and duration of upwelling and sinking, their driving mechanism, various associated features and the factors that affect these processes. It is achieved by analysing the temperature and density fields off the west and east coasts of India, and further conclusions are drawn from the divergence field of surface currents, wind stress and sea level variations.
