The behaviour and load of sediment transported along Sungai Punggor have been investigated in this research project. The transport of sediment in Punggor river and its estuary is studied to characterize the process of sedimentation. Sedimentation is an issue for Punggor river as fishing related activities are one of the activities carriedout at its river mouth. Characterized as agricultueal and suburban residential land, Punggor river reach have the roughness coefficient in ranging from 0.028 to 0.073 and the roughness coefficient at its estuary ranging from 0.072 to 0.107. From the sieve analysis, the sediment at Punggor river and estuary are classified as highly plasticity clay with high content of fine sand. The Atterberg tests results supported the sieve Z analysis classification with liquid index LI = 1.08 and plastic index PI = 18, denoting highly liquefied clay. The critical shear stress computed using Shields equation and Smerdon curve are 0.0156 NIrn2 and 1.97 Nlm2, respectively. Smerdon critical shear stress gives critical shear velocity Uc of 0.044 mls. Study has found that relationship between suspended solid and turbidity; and flow rate and sediment load are directly proportional where R2 equal to 0.96 and 0.72 respectively. The rate of sediment load flushed into the estuary of Punggor is between 0.027 m31s to 1.47 m31s.
