Groundwater levels as affected by swine waste lagoons in high water table soils
… in the region. This area typically has a high water table with sandy loam soils. There has been concern by state officials that these units could possibly cause contamination of groundwater in the surrounding area due to infiltration from the lagoons to the water table. The deep aquifer in …

Assessing the Performance of HSPF When Using the High Water Table Subroutine to Simulate Hydrology in a Low-Gradient Watershed
Modeling ground-water hydrology is critical in low-gradient, high water table watersheds where ground-water is the dominant contribution to streamflow. The Hydrological Simulation Program-FORTRAN (HSPF) model has two different subroutines available to simulate ground water, the traditional …

Estabilização de taludes em colúvio com o uso de cortinas ancoradas
… walls, even when considering a relatively high water table position. Initially a review of available methods is presented. The shortcomings of a Brazilian wedge method are worked around (herein referred as “proposed method”). The study of a hypothetical case, which represents a typical …

Groundwater investigation in the vicinity of Morden, Manitoba
… of 1967, an investigation of the areal ground-water conditions in the vicinity of Morden, Manitoba, was carried out. The study was prompted by concern about deteriorating and dying vegetation on the Canada Department of Agriculture Research Station at Morden, believed to have been caused by a …

Applicability of Stormwater Best Management Practices in the Virginia Coastal Plain
… 2014 as a compliance tool for evaluation of stormwater volume and quality, and necessitates use of urban stormwater best management practices (BMPs) to meet regulatory standards. Coastal Virginia is characterized by flat terrain, shallow water tables, and low permeable soils that may limit the …

Creation of a geographic information system database of Pacific Spirit Park
… vegetation damage and topography, areas with a high water table and along University Boulevard. The suggested course of action for GVRD park staff is to carry out additional research. Future research could compare the level of forest cover damage in Pacific Spirit Park with similar sites in …

Practical Use of Ground Penetrating Radar: A Survey of Coastal Historic Cemeteries in Brevard County, Florida
… of GPR in coastal environments where high water table, geology and saline conditions can limit the capability of the technique to resolve subsurface features. The third is to correlate data from the GPR survey with ethnographic information to enhance the protection and maintenance with …

In-situ measurements of radon concentrations in soil gas at a site on the Cape Flats
… some of the depths were not considered due to a high water table.) Atmospheric temperature, air humidity, wind speed and atmospheric pressure were measured using a portable weather tracker (Kestrel 4000). The highest radon concentrations recorded were 11000 ± 776 Bq.m-3 and 26900 ±1370 Bq.m-3 at …

Morphology, Mineralogy, and Hydrology of Soils in the Triassic Culpeper Basin of Maryland
… descriptions of each pedon were made and the water table was monitored in both open boreholes and slotted PVC pipes at staggered depths. Bulk samples of each horizon were collected for mineralogical and chemical analyses. Results indicate that hematite is the only iron oxide in the underlying …

Nickel laterites, origin and climate
… of a serpentinite protolith in a region with a high water table and relatively low topography, resulting in the formation of an oxide deposit. In addition silica precipitation is common in the upper horizons of the deposit, where it creates an indurated layer, protecting the deposit from …

The effects of rehabilitation management on the vegetation of Fenn’s, Whixall and Bettisfield Mosses National Nature Reserve – a cut-over lowland raised mire
… raised mire as well as bog pool vegetation and water table thresholds associated with these trends have been established. A landscape-scale vegetation survey was carried out three times over 9 years. Species abundance was correlated with average seasonal water table height, time since …

An evaluation of soil and water management practices on a lowland soil with poor natural drainage
… soil drainage. Excess moisture, because of a high water table and ponded surface water, restricts the range of crops that can be grown and influences farm management decisions regarding the nature and timing of field operations. When economic considerations lead farmers to commence field …
