Abstract: The Samanalawewa and Udawalawe reservoirs were built to harness the hydro-energy and irrigation potentials of the Walawe river in Sri Lanka. The recently completed Samanalawewa reservoir primarily generates hydropower while the Udawalawe reservoir, which was built in the 1960s, supplies water mainly for irrigation. With the addition of the Samanalawewa reservoir, located upstream of the Udawalawe reservoir, the government of Sri Lanka is planning to increase the irrigated area of the Udawalawe reservoir. The Samanalawewa reservoir is expected to act as an additional storage for irrigation water supply. A study was carried out to investigate the operational behavior of these two reservoirs. The model used in the study is based on stochastic dynamic programming (SDP) and simulation techniques. Since, the direct application of SDP for two reservoirs is limited by the dimensionality of the problem, a sequential decomposition method is employed in the model. The algorithm employed breaks down the system into single- reservoir subsystems and subsequently, each subsystem's operation is individually optimized using a SDP based optimization model and then simulated using a reservoir operation simulation model. The results indicate the usefulness of optimization techniques in planning reservoirs and deriving operational policies for them. The inclusion of the Samanalawewa reservoir reduces the irrigation water supply deficits at the Udawalawe reservoir.

为了利用Walave河水力发电和灌溉的潜力,建造了Samanalawewa 和 Udawalawe水库,刚建成的Samanalawewa 水库主要是用来发电的,而20世纪60年代建成的Udawalawe水库主要提供灌溉用水.Samanalawewa水库位于Udawalawe水库的上游,它的建成使得斯里兰卡政府计划增加Udawalawe水库的灌溉面积.准备将Samanalawewa水库作为灌溉用水的另一储备.为此对这两个水库的调度情况进行了研究.本研究所用的模型基于随机动态规划和模拟技术.由于直接运用动态规划受到维数的限制,本模型采用了时序分解方法这个算法将系统分解成单个水库的子系统,每个子系统采用基于随机动态规划的优化模型进行调度,再利用水库调度模拟模型进行模拟,结果表明优化技术在规划水库和获得调度政策方面是有用的.Samanalawewa水库的使用减少了Udawalawe水库灌溉用水不足的风险.
