Underwater acoustic mapping at Belum-Temenggor lake

Abstract

This study aims to investigate lakebed characteristics of Belum –Temenggor man-made lake using underwater acoustic sonar technology. Two types of underwater acoustic sonar gears were deployed at five different locations within the lake areas; the first system measured depth and was also capable to predict lakebed cover types. The latter system was used to construct intensity image of the lakebed at a better coverage and resolution. Results indicated that both systems were capable to provide sufficient information of lakebed cover types. This information will be useful to study in details how lakebed cover types affect the distribution of other aquatic species.
