In the semi-arid Amudarya delta region (Aral Sea Basin) the human-controlled hydrological regime is a major factor influencing ecosystem dynamics. Alterations to the flow of the Amudarya river, mainly to serve the needs of irrigated agriculture during Soviet times, have caused severe environmental degradation. Since independence, the former Soviet Union states of the basin are searching for new...

The present study attempts to optimize the outflow and the water distribution of entire Damodar catchment with the help of Artificial Neural Network(ANN). It is worth to mention that the large river valley project like Damodar Valley Corporation (DVC) with four dams and one barrage makes the simulation of Damodar more challenging, as it becomes a controlled flow system. Event of heavy floods ar...

[1] The potential and limitations of conjunctive use of surface and groundwater are explored for southern California’s water supply system. An economic-engineering network flow optimization model, CALVIN, is used to analyze the economic and reliability benefits from different conjunctive use alternatives. Flexible management of additional conjunctive use facilities and groundwater storage capac...

Cnidarian envenomations are an important public health problem, responsible for more deaths than shark attacks annually. For this reason, optimization of first-aid care is essential. According to the published literature, cnidarian venoms and toxins are heat labile at temperatures safe for human application, which supports the use of hot-water immersion of the sting area(s). However, ice packs ...

estimation of leakage in a network consists of several attributes, such as unauthorized use, minor leaks and networking events whose natures are different from each other. the most important attributes are large losses due to breakage and major leaks which in addition to wasting fresh water resources, will lead to water pollution and problems for the buildings. in this paper, leakage detection ...

The optimal Waste Load Allocation (WLA) problem, in general, is a mathematical model incorporating a water quality simulator within the framework of multi objective optimization. The goals are defined as to improve the water quality and minimize the total treatment cost of dischargers. The fraction removal levels of the dischargers are the decision variables. This paper explores the capabilitie...

Intelligent building technology for building operation, called the optimization process, is developed and validated in this paper. The optimization process using a multi-objective genetic algorithm will permit the optimal operation of the building’s mechanical systems when installed in parallel with a building’s central control system. Using this proposed optimization process, the supervisory c...

Most real world engineering design problems, such as cross-country water mains, include combinations of continuous, discrete, and binary value decision variables. Very often, the binary decision variables associate with the presence and/or absence of some nominated alternatives or project’s components. This study extends an existing continuous Ant Colony Optimization (ACO) algorithm to simultan...

 Background: Bromide is found naturally in groundwater and surface water. The rapid growth of industrial activities, drainage of surface runoff, and use of methyl bromide in pesticides has increased bromide discharge to the environment. Disinfection of water-containing bromide causes the creation of additional products of organo-halogenated that are considered cancer-causing agents. In...
