It is very important to dispose the water resources rationally. Rational disposition of water resources is the nucleus of sustainable water resources utilization, and is the important way to solve the district water resource shortage and raises utilization efficiency of water resource. A decision-making variable model is established by groundwater, surface water and precipitation. Water resourc...

Successful application of a TBM in a project requires investigating both the ground conditions and the machine and backup system design features. Prediction of the machine performance is very important as it has a big effect on the duration of the project and the costs. In this respect, both penetration rate and advance rate must be estimated. Utilization factor, which depends on the type of op...

water scarcity in iran has worsened as a result of population growth, increasing pollution, poor water management practices, and climate change. using proper utilization and management of wastewater can provide the ability to cope with pollution threats and take the opportunity to benefit from the new sources of water. in this study, the impact of water scarcity on the production and macroecono...

Anthropogenic modification of aquatic systems has diverse impacts on food web interactions and ecosystem states. To reverse the adverse effects of modified freshwater flow, adequate management of discharge is required, especially due to higher water requirements and abstractions for human use. Here, we look at the effects of anthropogenically controlled freshwater flow regimes on the planktonic...

− Distributed sensing for water quality monitoring provides important data that can be used to evaluate the characteristics of water according to specific requirements. The measurement of water parameters in extended areas requires the utilization of a high number of sensing nodes including multiple sensors, which can make difficult the management of the sensing devices to obtain high reliabili...

participation of workers in decision making commensurate with their functional capacity is very useful for the development of human resources which accelerates the goal attainment. participative management and its theoretical history in the west, leadership and management theories through utilization of the results of questionnair regarding the styles. of leadership, combination of personnel re...
