Abstract

Most of the river in Indonesia has a meander area especially located at the lower reach. Since the pattern of the community behaviour in Indonesia, people live in surrounding or along the river while the river plains and delta consist of alluvial soils, thus, meander migration usually occurs as a response to natural or manmade disturbances of the fluvial system. Meander River in urban area usually encourage sediment transport problem such as riverbed aggradations at the area surrounding inside of the bank then will decrease the river capacity in retaining flood while simultaneously eroding on the outer banks of meander bends. Regarding velocity distribution at the channel cross section, the minimum velocity is occurring on the inside of the meander, therefore some of the sediment loads is deposited. Related with the phenomena, protection against sedimentation and erosion along meandering river extremely needed. Previously, river adjustment within meander area are continually being made, therefore, eventually the gradient of a stream is altered to accommodate the volume of water and the velocity necessary to transport the sediment load. In this paper,understanding of various phenomenon’s in the meander area due to the sedimentation processes are described and propose the new concept of protection with low impact development (LID) approach.

Abstract

Flooding is one of the problems that often occurs in the DKI Jakarta area, which one of the causes is the change of land use in watersheds that were originally into development areas. Whereas, its often the cross section of the river will be disrupted due to the loss of the riverbanks and the narrower cross section of the river. In order to overcome this, the Jakarta Provincial Government in 2013 normalized several rivers that crossed the DKI Province and one of them was the Pesanggrahan River which will be further investigated. The purpose of this study is to analyze the effect of river normalization on erosion and sedimentation which will result in changes in the longitudinal and cross section of the river. To get an accurate map of theWatershed Area, Arc-GIS software is used while identification of river flow before and after normalization was carried out based on data from Central Office of River Region Ciliwung-Cisadane, Ministry of Public Works. Sediment samples were taken at 3 points on the river, upstream, middle and downstream, that were reviewed to determine the gradation of the sediment grains. The HEC-RAS application is used to simulate sediment transport on the river section before and after normalization. The simulation results are used to determine the cross section changes due to erosion and sedimentation and to determine the water level in the river. From the water level, the hydraulic radius can be calculated and then carried out sediment transport calculation using Ackers-White equation since the equation using grain distribution from range 0.02 – 4.94 mm. The results it was found that the sediment transport in the upstream point increased 155.11 tons / year,at the midpoint increased 89.64 tons / year and the downstream point decreased 0.28 tons / year.
