The Terengganu river mouth and related coastal area has been chosen to improve delineation process from satellite imagery data. Landsat 5 (1996) and Landsat 7 (2002) were used together with GIS capability to determine shoreline, sandy area and and the changes occur specially on sediment movement from 1996 to 2002. For methodology, RGB to IHS imagery conversion analysis has been used and classified using ISODATA (Iterative Self- Organizing Data Analysis) technique to detect the particular area. This technique had been introduced by Chang et al. (1999) and modification and development was made for Landsat images before it can be applied in this study. Satellite imagery on standardizing and processing technique for change detection analysis was used to improve results accuracy. Base on the result, shoreline and sandy area at the Terengganu river mouth were easily been detected using Landsat imagery. The delineation technique process was compatible and easy to use for fast shoreline and sandy area detection at coastal environment. Referring from the result also, Terengganu river mouth has having a minimal change on sedimentation from 1996 to 2000. The changes involved concerning accretion and erosion processes which possibly impact directly with human alteration.
