APPLICATION OF SIMULATION MODELS FOR MANAGEMENT OF COMPLEX WATER RESOURCES SYSTEM

Abstract

The increasing water demands as well as unfavourable climate changes in the past decades have led to increased pressure to existing water resources systems worldwide and in our country. The priority is to maintain, manage and upgrade the existing water resources systems so they can successfully match the increased water demand for various purposes. In the following paper, acknowledgments are commented obtained from simulation analysis of complex water resources system of cascade type, composed of existing two dams with reservoirs and planned water resources system with single dam and reservoir, as upgrade of the existing system, by application of simulation models. The input data are recorded hydrology time series of discharge for a period of 40 years, considered as sufficient amount of data to carry out reliable simulation analysis. In addition, the available data for the water demand are taken into consideration within the analysis. Primary purpose of the existing two-reservoir water resources system is matching the water demand for water supply of the population and irrigation needs. In order to assess the state and capacity of the existing cascade water resources system, firstly, is prepared simulation model for such purpose. Based on the accomplished simulation experiment for the existing water resources system, another simulation model is prepared including the planned single water resources system. Namely, the simulation modeling and analysis run are carried out for both water resources systems – the existing and planned. The simulation models are prepared with application of HEC ResSim software, released by the USACE Army Corps of Engineers.
