Simulation of Sediment Transport model for Elengy Gas Terminal within the Port Qasim Navigation Channel in the Deltaic Creeks System of Indus Delta Pakistan
Keywords:Tidal current, Tidal constituents, Near shore waves, Numerical model, Wind stress.
Simulation of a numerical model as laboratory technique for understating the coastal processes is being used to reduce the survey budget while planning for coastal zone structural projects. In this study, 2D MIKE 21 model was simulated to compare the laboratory results with field data of complex Indus deltaic creeks system and exploring the possibilities to adopt the model for future studies. Indus Delta formed at the mouth of River Indus has been focused since last century for the industrial development activities and hydrodynamical parameters are the major factors the preparation of design of development project and sustainable deltaic environment. Tide and wind generated wave induced flow pattern were established using the model domain from Ormara Pakistan to Dewrka India. The results of simulation of HD model are in line with the observed data, but slower than the historical data due to extended industrialization around the navigation channel, whereas, MIKE 21 NSW simulation results are as per historical data. The results of the model simulation encouraging and suggest that numerical models as laboratory techniques can be used in the Indus Deltaic creek system to generate accurate environment.
