Abstract

An alluvial river system is a dynamic system that can alter the hydraulic flow and sediment load. Sediment modelling can enhance our understanding of river morphology. This model has also proved to be a useful tool to overcome problems concerning sediment transport and sedimentation and to provide effective mitigation measures. This article discussed the concept of sediment modelling. The sediment transport simulation method used sediment river hydraulic – two dimension (SRH-2D), which is a hydraulic model for river systems developed by United States Bureau of Reclamation (USBR). The SRH-2D results showed that the Krueng Baro River underwent many sedimentations, and the increase in the height of the layers was observed during the simulation period. It examined the main categories of sediment transport models and presented the boundaries. Besides, this study also considered the constraints on the operation of Perusahaan Daerah Air Minum (Indonesian regional water utility company) (PDAM) and irrigation intakes because of the sedimentation in the Krueng Baro River flow, taking into account the structure of the Keumala weir. Specifically, this study thoroughly discussed the position and altitude of river aggradation and degradation to minimise conflict of interest between the PDAM and irrigation water supply because of sedimentation.
