Expert system for evaluation of nutrient pollution potential in groundwater from land application of manure.
(2004)
In recent years, groundwater contamination from animal husbandries has become a growing concern for the regulatory agencies and farmers. The animal husbandries usually dispose off the manure produced in the facility to the ...
The middle surface concept and its application to constitutive modeling of soils.
(2003)
The modeling of stress-strain behavior of geomaterials, such as soils, is key to the accurate analyses of complicated geotechnical engineering structures. Traditional elastoplastic modeling concepts, characterized by a ...
DIMENSIONAL STABILITY OF CONCRETE SLABS ON GRADE
(2011)
Drying shrinkage is one of the major causes of cracking in concrete slabs on grade. The moisture difference between the top and bottom surface of the slabs causes a dimensional or "shrinkage" gradient to develop through ...
Laboratory and model prediction of rutting in asphalt concrete.
(2003)
Rutting is one of the major distresses of flexible pavement. It is defined as the formation of longitudinal depressions under the wheel paths caused by the progressive movement of materials under traffic loading in the ...
Static and dynamic behavior of multiphase porous media: Governing equations and finite element implementation.
(2001)
The mechanical behavior of porous media such as geomaterials is largely governed by the interactions of the solid skeleton (or grains) with the fluids existing in the pores. These interactions occur through the interfaces ...
The Effects of Evaporation and Capillary Forces on Fluid Motion, Solute Transport, and Water Content From the Grain Scale to the Continuum Scale in Unsaturated Porous Media
(2019)
This work aimed to explore how fluid motion, solute transport, and water content are influenced by evaporation and capillary forces in unsaturated porous media, across a range of scales. Experiments were conducted from the ...
The fate and effects of aqueous film forming foam (AFFF) as it passes through a sand, soil, or activated carbon biofilter with appendices on high performance liquid chromatography and the Beckman Microtox Toxicity Monitor applications to AFFF.
(1982)
The sand biofilters exhibited removals of 90% and greater with a long term loading of 6-8 inches/week and 1000 ppm AFFF (V/V). Sand was found to be a satisfactory biofilter media. The soil biofilters plugged under the same ...
Graph-theoretic approach to the analysis and optimal design of water distribution network.
(1981)
Although emphases have been placed on the use of models developed on hydraulic network, the use of these models are by no means restricted to this area alone. Both models can quite easily be applied to all other networks ...
