Abstract:

This article analyses the connotations of water resources carrying capacity and its evaluation method, Selecting 9 main factors as the evaluation indexes, combined with fuzzy pattern recognition model and apply this model to comprehensive evaluation of water resources in Erdos. The results show that current exploitation and utilization of water resources in this region has reached a considerable size, under the current economic and technical conditions, the bearing capacity of water resources in this region has been relatively small, water resources supply-demand contradiction is so urgent.

Abstract:

Abstract Daily exploitation of the water network, collecting of data concerning the failure of water pipes and knowledge of the repair team are the basis of the data used in the process of effectively removing and identifying failures. The paper proposes a methodology to identify the risk of failure of the water supply system that uses risk indexes according to the proposed three-stage scale of risk levels. An example of application methods for the actual operational data broken down by analysis and risk assessment for bus cables and a separate analysis for the distribution network.

Abstract:

Water resources are important natural resources and play a key role in economic development and social life. China is one of the countries with the most serious water shortage in the world. In the next few decades, the contradiction between supply and demand of water resources will always plague China. Increasing the use of unconventional water resources to mitigate the water crisis is necessary way to achieve a sustainable development. There has been no effective standard yet in China to evaluate the exploitation level and potential of unconventional water resources. This study describes the

Abstract:

Aiming at overcoming the disadvantage of ignoring environment resources value loss caused by mineral resources exploitation in traditional GDP accounting, a new accounting method was put forward. Through analyzing the forms of environment damage caused by mineral resources development, the mine environment problem was divided into seven forms: natural landscape damage, vegetation destruction, geological disasters, air pollution, water pollution, solid waste pollution and noise pollution. Based on this classification system and general principle of value estimate for environment resources, the

The development effect of Song Fangtun Oilfield is mainly restricted by two factors which are geology and exploitation. In view of the main control factors in oilfield development, we selected two indexes,monthly average decline range and water content escalating rate to establish early warning system of blocks development effect. The system which has great practical application value, is sensitive to reflecting the monthly variation process of block development effect, and plays a certain guiding role in the development effect during the whole year.

The carrying capacity of water resources is one of the focuses in water resources research, and it has an important significance in measuring the effects of water resources on regional development. Wuhan City is selected as an example in this study. Eight indexes are selected to assess the carrying capacity of water resources in Wuhan City in recent three years based on the fuzzy comprehensive evaluation method. The results show that the degree of exploitation and utilization of water resources is relative high, and the potential of carrying capacity is relatively small. In addition, the contr

Abstract:

After the 2000s, the launch of very high-resolution satellites provided great water and irrigation network management personnel opportunities. Now, the water management staff have the opportunity to study and monitor water supply systems and exploitation conditions of irrigation systems remotely via satellite imagery. By using those satellite images, specialists can search for water bodies, detect defected place of irrigation systems, and monitor their technical condition. Another advantage of satellite imagery is that they capture large areas of the Earth, keeping water systems under control

Abstract Traditional indicators of water resource utilization degree and efficiency cannot show the stressed relationship between the level of water resource utilization and economic development level in a region. Therefore, this manuscript proposes a generalized index of socio-economic consumption level of water resources. The definition of the index is the ratio of water consumption change for GDP growth per unit, and the potential of water resources exploitation and utilization. The theoretical curve of this index has a rise period, a high value period, and a decline period, which correspon

In order to compare solar-hydrogen and the most used fossil fuels, the evaluation of the “external” costs related to their use is required. These costs involve the environmental damage produced by the combustion reactions, the health problems caused by air pollution, the damage to land from fuel mining, and the environmental degradation linked to the global warming, the acid rains, and the water pollution. For each fuel, the global cost is determined as sum of the market price and of the correspondent external costs. In order to obtain a quantitative comparison, the quality of the different co
