Documented responses of shoreline to submerged structures have shown more of erosion rather than accretion even though these structures were put in place to mitigate erosion, this could be as a results of prediction of shoreline response to submerged breakwaters (SBWs) were based on predictive model for generalized offshore breakwaters (submerged & emerged). In an attempt to create an exclusive predictive model for submerged breakwaters this study will monitor the changes in shoreline that has occurred in a study area that has these structures installed. The exact environmental and structural parameters governing the formation of salient at the lee of this structure will be deduced. This will be done using both aerial/satellite images and field study. An ideal prototype is available in Kerteh Coastal area of Terengganu of Malaysia, these SBWs were installed about 20 years ago to mitigate erosion as at that time. This paper will focus on the changes detected remotely using satellite images, multi-temporal satellite images of three years (2006, 2008 and 2009) was processed for this detection. The ENVI 4.8 software was adopted for this purpose. Results from the images showed that the area of the shoreline has reduced; for 2006-2008 there was a reduction of about 10% and for 2008-2009 there was a reduction of about 16%.
