pumps are among the early instruments invented by humans to be taken advantage of in the use of water utilities. design and operation problem of pumping stations is a type of mixed integer non linear programming, in which gradient based optimization methods are not efficient for solving complex problems of this type. in this regard, such evolutionary optimization algorithms as genetic algorithm...

Irrigation management has gained significance due to growing social needs and increasing command for food grains while the available resources have remained limited and scarce. Irrigation management includes optimal allocation of water for irrigation purposes, optimal cropping pattern for a given land area and water availabilities with an objective to maximize economic returns. In the present s...

This research intends to analyze the optimal operation pattern for fulfilling raw water demand, and it is conducted in integrated cascade reservoir of Duriangkang-Muka Kuning, Batam City, Indonesia. However, City economic center Riau Islands absolutely needs enough supplies support its development. The need predicted reach about 6,630.29 l/s 2025. Due population growth that estimated 1.8 millio...

This paper describes analyses being performed to aid in the development of operation strategies for the Long Term Flow Test at the Hijiori Hot Dry Rock reservoir, Japan. Testing has shown that the reservoir is dominated by flow in natural fractures that connect the reservoir to the far-field. When the injection flow is doubled, the production flow rate stays approximately constant. Also, during...

Author(s): Emami, Mohammad; Nazif, Sara; Mousavi, Sayed-Farhad; Karami, Hojat; Daccache, Andre | Abstract: The continuous growing demand for water, prolonged periods of drought, and climatic uncertainties attributed mainly to climate change mean surface water reservoirs more than ever need be managed efficiently. Several optimization algorithms have been developed optimize multi-reservoir syste...

The spatial distribution of petrophysical properties within the reservoirs is one of the most important factors in reservoir characterization. Flow units are the continuous body over a specific reservoir volume within which the geological and petrophysical properties are the same. Accordingly, an accurate prediction of flow units is a major task to achieve a reliable petrophysical description o...

this study concerns the scope to improve water flooding in heterogeneous reservoirs. we used an existing, in-house developed, optimization program consisting of a reservoir simulator in combination with an adjoint-based optimal control algorithm. in particular we aimed to examine the scope for optimization in a two-dimensional horizontal reservoir containing a single high permeable streak, as a...

the sefidrud dam was constructed and made operational in iran in 1962. the reservoir lost a considerable amount of its storage capacity in the first two decades of its operation when about 800 mcm sediment deposited in it and by considering the total capacity, 1800 mcm, the live storage capacity was reduced by 45 percent in 1980. the gilan project authorities have attempted to recreate the rese...
