  1. Hyperbolic soil parameters for granular soils derived from pressuremeter tests for finite element programs

    In the discipline of geotechnical Engineering the majority of finite element program users is familiar with the hyperbolic soil model. The input parameters are commonly obtained from a series of triaxial tests....

  2. A Critical Physical Geography of Urban Soil Contamination

    Anthropogenic lead (Pb) is widespread in urban soils given its widespread deposition over the course of the 19th and 20th centuries via a range of point- and non-point sources, including industrial waste and...

  3. Foliar Nutrient Concentrations Related to Soil Sources Across a Range of Sites in the Northeastern United States

    Understanding the supply of nutrients from various soil sources and the sensitivity of tree species to soil nutrient availability is critical for predicting the effects of declines in base cations due to acid...

  4. Snow-Patch Influence on Soil Biogeochemical Processes and Invertebrate Distribution in the McMurdo Dry Valleys, Antarctica

    The McMurdo Dry Valleys is the largest of the ice-free areas in Antarctica. Precipitation events in excess of 1 cm of snow accumulation are rare. During the winter, snow is transported by strong katabatic winds...

  5. The Stochastic Behavior of Soil Moisture and Its Role in Catchment Response Models

    The object of current efforts at investigating catchment response is to derive a physically based stochastic model of the watershed. Recent studies have, however, indicated that a limiting factor in deriving...

  6. Combined Assimilation of Streamflow and Satellite Soil Moisture with the Particle Filter and Geostatistical Modeling

    Assimilation of satellite soil moisture and streamflow data into a distributed hydrologic model has received increasing attention over the past few years. This study provides a detailed analysis of the joint...

  7. Response of Sagebrush Steppe Species to Elevated CO2 and Soil Temperature

    Elevated atmospheric CO2 may cause long-term changes in the productivity and species composition of the sagebrush steppe. Few studies, however, have evaluated the effects of increased CO2 on growth and...

  8. Impact of Soil Moisture–Atmosphere Interactions on Surface Temperature Distribution

    Understanding how different physical processes can shape the probability distribution function (PDF) of surface temperature, in particular the tails of the distribution, is essential for the attribution and...

  9. Comparing Infiltration Models to Estimate Infiltration Potential at Henry V Events

    It is useful to estimate infiltration rates and potentials for several reasons. Information about infiltration at a site may be to evaluate surface irrigation systems, to predict hydrologic conditions, and to...

  10. The Role Of Soil Test Information In Reducing Groundwater Pollution

    Testing soils for nutrients is expected to improve groundwater quality. However, it is unknown whether soil testing will improve groundwater quality sufficiently to decrease the demand for direct regulation of...
