The analysis of water balanced in Bendo Reservoir using Dynamic System

Abstract

This research was conducted to analyze balancing the storage capacity of the Bendo Reservoir with the quantity of water needed. Bendo Reservoir located in Nginden Sawo Village, Ponorogo Regency is one of the multipurpose reservoirs in Indonesia designed for irrigation, water supply, and simultaneously hydroelectric power. The water available is observed to be decreasing along with climate change, thereby, requiring an appropriate reservoir operational system. Several methods have been designed to achieve this purpose through the use of vast and complex variables but this study used a Dynamic Systems approach for analysis. Hhowever, involved the use of two scenarios in the simulation model to obtain the most optimum results. A period of 5 years was simulated and the result showed water shortage started in the 54th month for scenario 2, 49th month for scenario 1, and 46th month for the base model. Therefore, means scenario 2 has the most optimum conditions and recommended as the appropriate solution for Bendo Reservoir water distribution.
