Reconnaissance study on the need and feasibility to integrate a water distribution model in the DSS of PJT II: Using RIBASIM

Esselink, Abe Albert (2013) Reconnaissance study on the need and feasibility to integrate a water distribution model in the DSS of PJT II: Using RIBASIM.

Abstract:This research focuses on the water allocation process of PJT II (Jasa Titra 2) in the Citarum river basin, west Java province in Indonesia. The goal of this research was to do a reconnaissance study on the need and feasibility to implement a water distribution model in the DSS (Decision Support System) of PJT II. A water distribution model simulates the water allocation process in an area, based on the demand, availability and policy regarding the water allocation process. Currently there is no water distribution model implemented in PJT II’s DSS, and this research focuses on whether RIBASIM (River Basin Simulation Model) could fulfill this role. To answer the research objective, three research questions were formulated. This research gives answer on the questions: which characteristics should such water distribution model consist of, which components should the model contain, and whether the results that the model provides are useful for PJT II. The research was a joint cooperation between staff members of Deltares, Pusair and PJT II. The program that has been used for this research is RIBASIM; RIBASIM is a hydrological program to analyze the behavior of water balances in rivers under several hydrological conditions. RIBASIM allows policymakers to evaluate water balances due to changes related to the water-infrastructure, -operation and –demand. The input data consists of: hydrological network, water users, water suppliers, operation policies, economic data and scenarios. The input data for the hydrological network and water-users/suppliers are based on data that currently is being used by PJT II in their water allocation process, and it is attuned to the desired level of detail for PJT II. The structural foundation of the model was based on an existing model that already included parts of the Citarum river basin but did not have the right level of detail. Due to changes to the existing model, a new model was created that was in order with PJT II. In this research several scenarios were defined to determine the possibilities of this RIBASIM model were. Due to changes on both the supply and demand side, new water balances were simulated. The results of these simulations provide information on where and which effects may occur in these different water balances in the Citarum basin. The information out of these results is useful for PJT II in setting up new strategies or SOP regarding the water allocation process. This research shows that an implementation of RIBASIM as a water distribution model in a DSS for PJT II is feasible and would help PJT II in their water allocation planning process. RIBASIM would help PJT II setting up new policies about the water distribution in the Citarum basin. In a further step of a possible implementation, research needs to be done about the upstream part of the Citarum. This research main focus was on the downstream part from Jatiluhur reservoir, the upstream part still needs be defined properly.
