The potential for basin amplification of ground motion from significant seismic sources 100-200 km (62-124 mi.) from the Las Vegas Valley (such as the Death Valley Fault System) and Quaternary faults in the valley could provide sufficient energy to cause liquefaction. Key criteria of liquefiable soils coupled with a shallow groundwater table (less than 15 m (50 ft)) are met at several sites in ...

Abstract Background and purpose:In many regions especially in the north of Iran groundwater is the most important resource for drinking supply. A present study was carried out in the Tajan plain in northern Iran. The aim of this study was to evaluate the quality of groundwater. Materials and Methods:In order to constructing the groundwater quality index (GWQI) 3 main levels were composed select...

r a 200 .027 sent add gmail.c Summary Inverse geochemical modeling (PHREEQC) was used to identify the evolution of groundwater with emphasis on arsenic (As) release under reducing conditions in the shallow (25–30 m) Mississippi River Valley Alluvial aquifer, Arkansas, USA. The modeling was based on flow paths defined by high-precision (±2 cm) water level contour map; X-ray diffraction (XRD), sc...

To study the relationship between deep groundwater productivity and lineament, we use several lineament maps which are lineament map, lineament length density map, lineament cross-point density map and others from Remote Sensing. The avenue script files for calculating the lineament statistics, the lineament length density, lineament cross-point density value and the distance between a groundwa...

nowadays, water supply for sustainable development is one of the most important concerns and challenges in most countries of the world. due to determination of groundwater potential zones are one of the important tools in the conservation, management and utilization of water resources. thus, the present study aimed to prioritize the effective factors on groundwater potential and its susceptibil...
