Buffer strips have been widely recognized as to promote infiltration, deposition and sorption of contaminants for protecting surface water against agricultural contamination. However, such strips do not intercept all contaminants, particularly soluble ones. Although preferential flow (PF) has been suggested as one factor among several decreasing the efficiency of buffer strips, the mechanisms i...

Apulia, in the absence of surface water, is one of the Italian regions which satisfy their water requirements by drawing large quantities (over 40%) of its water from underground resources. The large amounts drawn from these resources in the last few years due to increasing human activity on the territory has determined a general and inevitable reduction of the quality of the underground water ...

In the construction of a building, it is necessary to minimize construction period and secure enough work space for stacking of materials during the construction especially in city area. In this manner, various top-down construction methods have been developed and widely used in Korea. This paper investigates the stress variation of underground structure of a building constructed by using SPS (...

The solutions to deal with the water crisis are summarized into two strategies for managing resources and extraction of new sources water. In Iran, due geographical climatic conditions, management has a high priority. One methods control store in wet periods using dry is construction underground dams. most important problem development creation dams complexity determining suitable areas study a...

Abstract Using goof as water storage space plays a vital role in the ecological environment and economic development of arid mining areas, while rock strength stability coal pillars underground reservoirs are closely related to creep process. In this work, triaxial creep-seepage tests were conducted for samples develop new insights into behavior permeability evolution. The results showed that d...

The western mining areas of China, which are rich in coal resources, lack water resources. Large-scale and high-intensity China’s has led to the loss groundwater Underground reservoirs mines an effective means achieving protection utilization resources these areas. One important standards for safety underground reservoir a mine involves checking whether development cracks pillar dam body, under...
