according to the low efficiency of irrigation and drainage networks and water distribution in iran, simulating water flow and sensitivity structures and networks is considered as a new approach to evaluate the performance hydroelectric projects in the country. in this study, because of reduced water supply and distribution, especially in downstream irrigation and drainage networks varamin to ev...

background: almost one third of the global population is living in developing south asia where disease occurrence is high especially in rural areas and people are unaware of water-borne diseases and cost of illness. methods: the quantitative approach involved questionnaire based study (n=50 households). the community awareness, the occurrence of water-borne diseases with related cost of illness...

background: provision of safe drinking water is one of the basic needs of every society and it will only be possible through preventive and comprehensive management of drinking water security programs such as haccp. hazard analysis critical control point (haccp) is an internationally accepted process control system which includes recognition and determination of risk factor properties of proces...

This paper determines the application of a model predictive control (MPC) technique to improve the behavior of the water network supply system, to maintain stable operation of the water flow rate, and reduce the operational cost by manipulating the pump speed. The MPC algorithm is one of the most common automatic control system that has got a wide spread application in process industry. MPC is ...

A rainwater harvesting system (RWHS) is an alternative water resource that collects and stores rainwater from rooftops. It helps smooth out variations in water supply and sustainable water resources management. In this study, we investigated the potential benefits from sharing RWHS with nearby neighbors in a community. We introduced different mean, variance, and correlation in water demand for ...

The mixed linear programming model is commonly recognized to be an effective means for searching optimal reservoir operation policy in water resources system. In this paper a multi-objective mixed integer linear programming model is set up to obtain the optimal operation policy of multi-reservoir water supply system during drought, which is able to consider the operation rule of reservoir-group...
