Surface Effects of Ground Water Flow Patterns - Bottineau and Mountrail Counties, North Dakota
<p>In the resolution of patterns of groundwater flow, certain surface expression is noted as being helpful. Vegetation has been used in other areas as an indicator of the chemistry of groundwater, but this type of exploration may be expanded to include physiography as well as vegetation. </p><p>The …

The Effect of Faults upon Ground Water Flow in the Baton Rouge Fault System
… Rouge area, which are the main source of freshwater. Beds dip and thicken toward the south. Aquifers in the Baton Rouge area are disrupted by the BRF. Aquifers contain fresh water in the updip (north of the BRF) and saline water in the downdip (south of the BRF) directions. Saline water has …

A Quantitative Analysis of Ground-Water Flow Toward Branson Missouri From Table Rock Reservoir
… coupled with a substantial change in water level in the White River valley resulting from the construction of three major reservoirs, levels currently induce approximately 1.1*10⁶ gallons of water per day to flow out of Table Rock Lake toward wells in Branson. Thus a major portion of …

EFFECTS OF GROUND-WATER FLOW ON SOIL CHEMISTRY, NUTRIENT AVAILABILITY AND PLANT SPECIES DISTRIBUTIONS IN FOUR NEW YORK STATE FENS
… settings with high fluxes of calcium-rich ground water has been observed but not fully explained. In fens, ground-water discharge patterns induce spatial gradients in water chemistry that may determine vegetation patterns through effects on nutrient availability. However, linkages among …

An assessment of the potential to use water chemistry parameters to define ground water flow pathways at Grand Canyon National Park, Arizona
… of this study is to assess the potential to use water chemistry parameters to determine ground water flow pathways at the south rim of Grand Canyon National Park, Arizona. South rim spring, ground, and surface waters and one north rim spring were sampled from September 1992 through September …

Ground Water Flow and Water Resources Investigation of the Auburn, Summers and Shakertown Springs Karst Ground Water Basins, Logan and Simpson Counties, Kentucky
… springs, Auburn and Summers Springs, to meet its water requirements. Besides being extremely vulnerable to contamination, the springs often discharge and insufficient volume of water needed for public consumption and dilution of the City’s treated wastewater. Thus the City wishes to find an …

Estimation of a water budget for Agnes Marsh, Grand Forks County, North Dakota
… hydrological impact to the marsh by a declining water table in the aquifer. The purpose of this study was to determine how Agnes Marsh interacts with the underlying Elk Valley aquifer and how sensitive the marsh is to declining water levels in the aquifer. </p><p> Three methods were used to …

Comparison and correlation of lithostratigraphic and hydrostratigraphic units of southwest area 20, Pahute Mesa, Nevada test site
… properties of the rock that affect potential ground-water flow. Hydrostratigraphic units represent an improved method of defining potential ground-water flow by identifying and grouping hydrologic units based upon the porosity and permeability of the rocks--not on geologic contacts, thus …

LITHOLOGIC AND HYDROGEOLOGIC CONTROLS ON THE OCCURRENCE, TRANSPORT, AND FATE OF MTBE IN FINE GRAINED GLACIAL-LACUSTRINE SEDIMENTS
In April of 1994, a leaking 60,480L gasoline underground storage tank was removed from George’s Conoco in Ronan, Montana. Investigations discovered a free product plume extending under Highway 93, with dissolved phase contamination (including MTBE) extending 460 m west to Spring Creek. Though …

Hydrogeology and Simulated Water Budget of the Rio Cobre and Rio Minho-Milk River Basins, Jamaica, West Indies
… A quasi three-dimensional finite-difference groundwater flow model was used to conceptualize flow conditions and establish a hydrogeologic budget of the region. The Rio Cobre and Rio Minho-Milk river basins lie on the Clarendon Block, an area with a complex geologic history. The geologic …

Estimation of leakage between the shallow and principal aquifers in the Las Vegas Valley Water District's main well field, Las Vegas, Nevada
… aquifer was recharged by upward leakage of ground water from the principal aquifer. Presently recharge to the shallow aquifer is infiltration from over-irrigation which poses a potential threat to the quality of the principal aquifer. To evaluate this contamination potential, water levels …
