Application of expertise services for coastal infrastructure development

NIOT functions with a mandate to develop application-oriented technology in ocean related areas.  Application of NIOT’s expertise ranges from planning of port layouts, feasibility studies, design of navigational channels, environmental impact assessments & monitoring studies, supported by data obtained from real time field measurements.

Field studies include collection of Hydrographical, Side Scan Sonar surveys, Shallow Seismic, Magnetometer, Current and Tidal data. Additional data consists of collection of historical data pertaining to shoreline changes, littoral drift and beach erosion, coastal and submarine geology, soil properties, tides and currents available from various agencies to correlate the field data. Ocean going survey vessels and boats are used in the process of geophysical surveying in deeper and shallower areas.

Processed field data provide information, which is mapped to obtain a wholesome description of seabed features, subsurface sedimentary strata, engineering properties and classification of soils. Integration of the processed seabed data, sedimentation profiles and hydrodynamic regime provide real time inputs for mathematical modelling, based on the output of which recommendations on technical feasibility and predictions for future conditions of any development proposal is made.
