Seasonal variations and yearly trend evaluations of sedimentation loads: a case study at Chalok River, Terengganu, Malaysia

The aims of this study were to determine the relationship between seasonal variations (wet and dry periods) on sedimentation loads and to identify the yearly trend of sedimentation loads at Chalok River, Terengganu, Malaysia from 2003 to 2008. It was found that wet and dry periods influenced the tra...
