events and accidents in drinking water distribution networks are among cases that lose water and increase the rate of non revenue water. network events in addition to wasting water can cause destruction, traffic jam, pressure reduction, pollution and enormous reconstruction costs.the main focus of this study is to statistically evaluate these incidents and to develop an analytical method to pre...

background the non-revenue water refers to a difference between the volume of water entering the system and billed authorized consumption. objectives the main purpose of this study is to determine the volume of non-revenue water in order to recognize the factors influencing water losses so that the information gathered can used in non-revenue water reduction management. materials and methods ka...

correct estimation of water inflow into underground excavations can decrease safety risks and associated costs. researchers have proposed different methods to asses this value. it has been proved that water transmissivity of a rock joint is a function of factors, such as normal stress, joint roughness and its size and water pressure therefore, a laboratory setup was proposed to quantitatively m...

Complex water networks, which have been structurally organized into Regional Supply and Urban Delivery networks from a functional perspective, are facing more challenges in their real-time control because of the reduced water resources, intensive energy requirements and increased attention towards the environmental impact of water use. Optimal management of complex water networks involves more ...

In order to prevent and reduce water pollution, promote a sustainable use, protect the environment and enhance the status of aquatic ecosystems, this article deals with the application of advanced mathematical techniques designed to aid in the management of records of different water quality monitoring networks. These studies include the development of a software tool for decision support, base...

the three practical steps that are need to be taken by government agencies in order to increase irrigation efficiency include economic motivation for optimization of water use, modification of existing irrigation systems in the short term and modernization of traditional methods in the long-term plan. the present research aims at identifying farmers' knowledge regarding irrigation and water iss...
