Grain-size characteristics of aceh's coastal deposits

Abstract

This study investigates the grain size characteristics and sediment types of the Aceh's coastal deposits that are primarily based on the sieve analysis. This study is mainly driven by two reasons. Firstly, this study is a preliminary effort to identify coastal sediment in the Aceh coastal areas. Secondly, this information is important to interpret the support mechanism of sediment during transportation and depositional processes. In this study, many sediment deposits from both the east and west coasts of Aceh were collected. Laboratory sieve analysis was carried out to these samples. Then, further analysis of this sieve analysis results is carried out. The analysis reveals the past transport mechanism of this study sand deposits which is river's channel. However, such finding should be investigated further as all the tested sand were taken at the top surface and big main rivers are not indicated at both sand locations.
