Hydrogeochemical indicators of groundwater flow systems in the Yangwu River alluvial fan, Xinzhou Basin, Shanxi, China.
Based on analysis of groundwater hydrochemical and isotopic indicators, this article aims to identify the groundwater flow systems in the Yangwu River alluvial fan, in the Xinzhou Basin, China. Groundwater delta(2)H and delta(18)O values indicate that the origin of groundwater is mainly from precipitation, with local evaporative influence. d-excess values lower than 10% in most groundwaters sug...
متن کاملsources of nitrate and bromide contaminants of groundwater in alluvial aquifer of arak, iran
the present study investigated no3- and br- contamination in groundwater of arak aquifer of markazi province. correlation and factor analysis were used to detect interrelation and sources of concentration of no3- and br- ions and others physicochemical variables. no correlation was observed between no3- and others contents, but positive correlation was identified between br- with other major va...
متن کاملControls on alluvial fan long - profi les
Water and debris fl ows exiting confi ned valleys have a tendency to deposit sediment on steep fans. On alluvial fans where water transport of gravel predominates, channel slopes tend to decrease downfan from ~0.10–0.04 to ~0.01 across wide ranges of climate and tectonism. Some have argued that this pattern refl ects grain-size fi ning downfan such that higher threshold slopes are required just...
متن کاملThe Source, Flow Rates, and Hydrochemical Evolution of Groundwater in an Alluvial Fan of Qilian Mountain, Northwest China
Major ions and selected environmental tracers (D, 18O, 3H and chlorofluorocarbons (CFCs)) were employed to determine the source, flow rates, and hydrochemical evolution of groundwater in an alluvial fan along the front of the Qilian Mountains, which serves as an important groundwater reservoir in northwest China. Temporal and spatial variations in ion concentrations were limited near the upper ...
متن کاملIdentifying sources of groundwater nitrate contamination in a large alluvial groundwater basin with highly diversified intensive agricultural production.
Groundwater quality is a concern in alluvial aquifers underlying agricultural areas worldwide. Nitrate from land applied fertilizers or from animal waste can leach to groundwater and contaminate drinking water resources. The San Joaquin Valley, California, is an example of an agricultural landscape with a large diversity of field, vegetable, tree, nut, and citrus crops, but also confined animal...
