Uzbekistan is one of the most water resources limited regions and it needs better sustainable management. The global ecological problem as Aral Sea disaster makes more urgent not only for nation but also all CentralAsian region. Region to be developed by following SDG same time save resources. balance ground in region environmentally safe enough quantity hydrologically. It due use huge number w...

An econometric analysis of Hong Kong’s monthly per capita water usage for the 25-year period of April 1985 through March 2010 reveals that per capita usage is insensitive to price but dependent upon past usage, per capita income, weather, and seasonal factors, with rising income countering what would otherwise be a downward trend. Given Hong Kong’s current inflationary environment and large gov...

BACKGROUND Non-touch fittings have been reported to be susceptible for Pseudomonas aeruginosa accumulation. A number of factors may contribute to this, including the frequency of usage, duration of water stagnation, or presence of plastic materials. Programmable non-touch fittings are appearing which allow regular automated post-flushing with cold water to prevent water stagnation. However, the...

In the semi-arid area of West Texas, drinking water is a precious commodity. Drinking water sources include water from Lake Meredith and groundwater from the Ogallala Aquifer. Water usage in this area includes farming and irrigation, municipal use or cooling water for electricity generation. As population continues to grow and water usage increases, especially during periods of drought, the ava...

A model predictive control (MPC) framework, exploiting both feedforward and feedback control loops, is employed to minimize large disturbances that occur in military water networks. Military installations’ need for resilient and efficient water supplies is often challenged by large disturbances like fires, terrorist activity, troop training rotations, and large scale leaks. This work applies th...

the price of water in agriculture plays an important role in the water allocation management. therefore, the optimum strategies of cropping pattern could be designed when water price analysis are considered in a predetermined economic framework. in the present study, a programming model was developed using the genetic algorithm for optimal water allocation in the eastern north of khuzestan prov...

abstract among different water usage in iran, agricultural sector with 94 percent is the largest water user. considering the share of agriculture in water usage, farmers are the main factor in water resources management. therefore, optimal utilization of irrigation and drainage networks would depend on farmers’ effective role. due to the limited water resources in different country regions, inc...

Abstract Water management is crucial for human life, and precise measurement instruments are necessary to ensure efficient utilization. This study aimed develop a water usage system using ultrasonic flow meters microcontrollers. The results were displayed on screen sent via modbus remote devices. To validate the accuracy of system, comparison between manual was conducted, showing an error value...
