This study was conducted at Kenau River at Sungai Lembing, Kuantan. The objective of the study is to determine the changes of sediment characteristics at Kenau River from year 2008 to year 2019. In order to determine the change of sediment properties regarding size, density and fall velocity, several related were conducted in the laboratory. Particle size distribution was carried out to classify properties of the soil sample. From the soil classification test, this soil is gravel soil with fine soil and silt. The second objective is to determine the best equation to predict the sediment at Kenau River. The cross section of river had measure and compare. It overcome huge changes after 11 years. The characteristics at Kenau River required to identify because it may affect the flow of the river during a usual day and flood event. This study involves five location of study area. The sediment sample sieving test results was classified using Unified Soil Classification System (USCS). The soil classification at Kenau River for every station is almost entirely classified as Poorly Graded Sands (SP). The flow rate data also had record for every location by using current mer. The highest flow rate was recorded about 2.940 m3/s located at Station 2. The lowest flow rate recorded is about 1.523 m3/s located at Station 4. The best equation to be used to determine sediment rate at Kenau River is Ackers-White equation for sediment transport.
