Nomograms to estimate peak storm surges generated by tropical cyclones impinging on, the east coast of India are prepared using Jelesnianski's. SPLASH (1972) model. The. pre-computed nomograms accommodate fixed values for pressure drop, radius of maximum wild, vector motion of storms and offshore bathymetry. Two sets of nomograms are presented -one for the northeast coast of India where the slope of the continental shelf is extremely shallow -the other for the remaining east coast where the slope in general is extremely steep. A nomogram to correct the magnitude of the peak surge for tidal effects is also prepared for the notheast coast of India where the semidiurnal tide range is large. A method to estimate total sea level elevation along a coastal stretch by means of nomograms is given for the northeast coast of India.
