Abstract:
An echo-sounder was run along a shipping route of Kuala Terengganu river estuary in 16th February, 2007 to study the bathymetric image and its characteristics. The echosounder image indicates the depth over a 1 OOm width, along the surveyed route varies from 2m to Sm. Data were collected starting along a predetermined transects with the respective depths to be recorded in a laptop. Results from analysis using Surfer 8 software programs indicate the deepest part and the shallowest part of the estuary. Hydroacoustic method was an effective way to map and monitor important physical and geological parameters such as bathymetry and bottom characteristics. The image data that have been produced indicates that some areas have been dredged perhaps to deepen the channel prior to the Monsoon Cup competition-an international event. Frequent survey should be carried out in the area to ensure the channel has sufficient depth for safe navigation or international event such as monsoon cup competition.
