Fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the Earth’s crust. Furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. In this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...
Abstract In this research, Geophysical methods Ground Penetration Radar (GPR) and Geoelectric have been used to detect hidden Quaternary faults in alluvial sediments located southwest of Chitgar Forest Park (District 22 of Tehran). The study of profiles (GPR) identified areas such as fault. The results obtained from two Geoelectric profiles indicate that there are two zones with low electrical...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
basins leading to tabriz plain are part of the sub-basins of urmia lake basin, which is located in the east azerbaijan province and in the north-western part of iran. the area of this basin is 5397 km2, and agriculture is one of the main sources of income for the people, which is dependent on groundwater and surface water resources. in this study, an attempt was made to investigate the basins l...
Fault location remains a challenging problem in order to restore power supply rapidly. In this paper, a novel single-terminal traveling wave fault location procedure is proposed in a radial distribution network. Firstly, the propagating speed of zero mode traveling wave is determined by BP neutral network method. Then the preliminary estimation of fault distance is calculated based on the diffe...
Mass movements are usually natural erosion, but the human can aggravate it by operations such as mining, road construction and destroying the natural vegetation. The purpose of this study is to identify the factors influencing the occurrence of landslides by using a probabilistic model Weight of Evidence and Geography Information System in the Siyahbisheh Watershed. 132 landslide points are ide...
This paper presents the design, simulation and implementation of an adaptive mho distance relay to compensate during a phase-to-phase fault with fault resistance using the KU method. The phaseto-phase fault with fault resistance occasionally produces a trajectory of impedance outside the zone of the distance relay protection. Therefore, in this case, the distance relay will not send the trip co...
Abstract Background and purpose: Urban developments and population growth have dramatically increased all kinds of municipal solid waste (MSW) generation. Hence, treatment and disposal of municipal waste is one of the main concerns in urban environmental management. The aim of this study was to determine suitable locations for landfill based on environmental criteria using Boolean and Weight...
this paper presents a fault location technique for transmission lines with minimum current measurement. this algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. these current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...
In this paper the problems of protecting a cross-bonded cable system using distance protection are analysed. The combination of the desire to expand the high voltage transmission grid and the public's opinion towards new installations of overhead lines (OHL), more and more transmission cable systems are being laid around the world. Differential protection is often used for the main protection o...
