As our country is vulnerable to several kinds of ocean / water body related disasters, several methods should be adopted for predicting and assessing these kind of disasters and thereby predicting their future arrivals. Numerical modelling, vulnerability index mapping, hazard assessment etc. should carried out at regular intervals for accelerating mitigation activities. For all the above, the height of terrain with respect to Mean Sea Level (MSL)is the most pertinent factor. The topography of terrain can be estimated using field surveys like DGPS surveys, Dumpy level, Total station etc.
