Unexpected shortage of water supply is common phenomena especially in dense population such as in hostels. Water supply at the students’ hostels is usually drawn from tank at the roof top of the building. Apparently there is no early warning system to monitor the tank water level when it has reached the critical level. The situation worsened when there is no personnel or technician in-charge to...
in the recent decades, due to water shortage problems, most countries have adopted their new policies from water supply management to water demand management . the main objective of the present study is a simulation of water market in order to determine the role of market in the balance between water supply and water demand and to analysis impacts of irrigation water sharing policies on the cro...
Aspects of transboundary, water shortage, and fisheries issues are discussed in the context of the recently completed Global International Waters Assessment (GIWA) for the Pacific Islands. The region encompasses some 30 million km2 and approximately 12% of the world's ocean space, and features great geographic, demographic and developmental diversity. Global change, especially sea level rise an...
abstract different strategies are existed for adjusting with water shortage, of which the strategy of suitable policies adoption by determining optimum production function can be mentioned. water shortage and quality degradation of soil and water resources is one of main factors of production reduction. therefore, this study was carried out for determination of tomato sensitivity coefficients a...
During the past decades, the traditional state monopoly in urban water management has been debated heavily, resulting in different forms and degrees of private sector involvement across the globe. Since the 1990s, China has also started experiments with new modes of urban water service management and governance in which the private sector is involved.

This paper proposes and analyses a new demand response technique for renewable energy regulation using smart hot water heaters that forecast water consumption at an individual dwelling level. Distributed thermal energy storage has many advantages, including high overall efficiency, use of existing infrastructure and a distributed nature. In addition, the use of a smart thermostatic controller e...
