Measurement of Depth of Seabed and Sea Flow Rate Under SuraMadu Bridge Madura Side for Determination of Mooring Turbine Construction Sea Power Plants

Abstract

SuraMadu bridge as one of the bridge on Madura have a strategic function.    Due  to  the  rapid  population  growth  on  Madura,  the people  require  a  strategic  and  cheap  electricity  for  industrial development  especially  in  the  region  of  Surabaya  and  Madura. The  purpose  of  measuring  the  depth  of  the  seafloor  and  ocean currents on strait of Madura is to know the contour of the seabed and  the  speed  of  ocean  currents  around  the  masts  of  the SuraMadu bridge of  Madura. To  measure  the  depth of  a seabed and the ocean currents at a various points from SuraMadu Bridge are required to predict the characteristics of the ocean. The results showed the depth of the waters and the speed of ocean currents in the  research  area  around  the  SuraMadu  bridge  ranges  from  12 meters up to 15 meters with sea current velocity between 0.3 m /s²    up  to  1.6  m  /s².  The  research  method  used  the  case  study method. This research is conducted covering activity of location survey.  Furthermore,  bathymetry  data  analysis  and  processing bathymetry data analysis are performed.
