A unique model of resources consumption drag of urbanization is developed by employing the neo-classical production model and the urbanization relation model. By using this model, it is viable to estimate the resources consumption drag, measured as the reduced speed of urbanization from resources consumption and environmental services. In terms of reduced urbanization process, the aggregated an...

Dominance of arid and semiarid climate in a vast area of Iran along with the water consumption growth necessitates a more sophisticated planning, a more efficient operation towards an optimal allocation and conservation of water resources in the country. In recent decades many countries, including Iran, have adopted increasing block tariffs for domestic water management. This policy is based on...

Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand. Here, analyses of climate change and direct human impacts on the terrestrial water cycle are presented and compared using a multimodel approa...

Household water consumption is a part of the human related water cycle that can get into the core of water resources management. Analysis of water consumption data can reveal great potentials of individualized water services planning. Data mining is the process of identifying and extracting potentially useful information from data sets. Self-Organizing Maps (SOMs) is a data mining technique tha...

Thermoelectric power production comprised 41% of total freshwater withdrawals in the U.S., surpassing even agriculture. This review highlights scenarios of the electric sector's future demands for water, including scenarios that limit both CO 2 and water availability. A number of studies show withdrawals decreasing with retirement of existing electricity generating units. Consumption, the evapo...

Increases in corn cultivation for biofuels production, due to the Energy Independence and Security Act of 2007, are likely to lead to increases in nitrate concentrations in both surface and groundwater resources in the United States. These increases might trigger the requirement for additional energy consumption for water treatment to remove the nitrates. While these increasing concentrations o...

In the Yellow River basin, China, ecosystems suffer from the overexploitation and utilization of water resources, resulting in various environmental impacts. Consideration must be given to both human and ecosystem water requirements in water resources management. A water footprint (WF) is a tool for estimating industrial, agricultural, commercial and household water requirements and for examini...

Water requirements in many large water supply systems are provided by mixing water withdrawal from surface and underground resources with different quantity and quality.Water supply from underground sources requires energy consumption and surface water resources are limited and unstable.The aim of this research is managing optimal supply of required water of system with minimum energy cost and ...
