(mentor) Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2012-01-23 Abstract An overdose of sediment from the Cilalawi River is going into the reservoir Waduk Jatiluhur. This is resulting in the problem of reservoir capacity reduction. With water still coming from different rivers, the future will be inundation. In this matter the recommendation for this problem is check dam(s) and changing land use, stated by the local government, Perum Jasa Terta II (PJT II). These solutions can both reduce sediment transport in the river by respectively decreasing flow velocities and reduction in erodibility. The Cilalawi River and reservoir Waduk Jatiluhur are located in the province of Purwakarta, West Java, Indonesia. Cultivation, forest and buildings surround this river. Residents in this area are using the river for waste disposal, private fishing, washing and recreation, while chemicals and excreta heavily pollute it. What is more, the PJT II manages the policy for rivers in West Java region. On the contrary, there is currently no policy concerning the Cilalawi River, although, recommendation has been written for the described problem. Therefore, the goal is to use the design of a functional check dam to estimate the impact of the civil structure on erosion and sedimentation in the watershed. Land use changing is no option, because of the large surface area to treat, the additional high expenses and the essential sawah existence with high erodibility. The research questions to the theme and to achieve the goal are: 1. Which characteristics of the Cilalawi River and watershed are responsible for the sedimentation and erosion? 2. What would be the design of the functional check dam for the Cilalawi River? a) What are the requirements for the new check dam? b) What will be the time horizon of the check dam till its expiration? c) What does the designed check dam look like in the phase of preliminary design?
