Abstract
Rapid urbanization has an accelerated impact on catchment hydrology and geomorphology due to land use and land cover changes as a result of anthropogenic development activities in river catchment areas that causes increase surface runoff and higher sediment yield. The present study investigate the channel changes and sediment transport phenomena, including bed material movement from the upstream to the estuaries of the Pahang River Basin, Peninsula Malaysia. River geometry survey associated with the spatial variation in sediment transport has confirmed that changes in river bed profile occurres due to the erosion and sediment deposition along Pahang River. The sediment distribution size for the Pahang River was very coarse sand and gravel after December 2014 flood which subsequent. River geometry survey showed of gentle slope that can induce lower discharge typical of alluvial rivers relating to flood events. Quantitative assessment of sediment load is therefore of critical importance for future river basin management.
