    Notes: : Operation of a storage-based reservoir modifies the downstream flow usually to a value higher than that of natural flow in dry season. This could be important for irrigation, water supply, or power production as it is like an additional downstream benefit without any additional investment. This study addresses the operation of two proposed reservoirs and the downstream flow augmentation at an irrigation project located at the outlet of the Gandaki River basin in Nepal. The optimal operating policies of the reservoirs were determined using a Stochastic Dynamic Programming (SDP) model considering the maximization of power production. The modified flows downstream of the reservoirs were simulated by a simulation model using the optimal operating policy (for power maximization) and a synthetic long-term inflow series. Comparing the existing flow (flow in river without reservoir operation) and the modified flow (flow after reservoir operation) at the irrigation project, the additional amount of flow was calculated. The reliability analysis indicated that the supply of irrigation could be increased by 25 to 100 percent of the existing supply over the dry season (January to April) with a reliability of more than 80 percent.

    Notes: Abstract The three-dimensional groundwater flow model MODFLOW and the one-dimensional consolidation model are coupled and calibrated to simulate the piezometric levels and land subsidence in the complex multi-aquifer system of the lower Central Plain of Thailand. The mathematical models are calibrated against historical data for the period 1955–1990 by considerably updating the system conditions used by previous studies. The aquifer system responses to different pumping schemes are then predicted for the period 1991–2010. The modeling procedure is carried out in close consultation with the Department of Mineral Resources (DMR), Royal Thai Government. The conclusions of the study will allow the DMR to develop and implement updated groundwater management policies, land subsidence control strategies and action programs in the Bangkok Metropolitan Area.
