COASTAL HYDRAULICS & ENGINEERING


    Pakistan coast is influenced by intensive SW Monsoon waves and currents including erosion and siltation. The deposition of silt by river Indus also interacts with the shore processes. The inundation of the coast therefore, requires a systematic hydraulic and hydro-dynamic investigation all along the coast. Data on waves, tides, currents and littoral transport are collected for application in coastal protection, planning of ports etc.


Monsoon Waves
    Numerical models of harbours, bays, estuaries for investigating the effects of tidal heights and currents are also prepared. Occupance and path of cyclones and effect of storm surges on the coast are studied for evaluating shore erosion, through Numerical Models.

    NIO has undertaken studies to evaluate energy potential from the currents in the creek system which is spread over 2000 sq. km. Theoretical evaluation indicates that about 1100 MW of electricity can be generated from this renewable energy resource.

    In addition to these, data and sites surveys are being carried out for utilisation of wave energy and ocean thermal energy.
