Latest Soil mechanics Stories
Researchers studying how fluids travel through nanoscale channels were surprised to discover that the fluids don't flow equally well in all directions.
The extended Coulomb failure stress (ECFS) criteria and anisotropic porosity and permeability tensor at micro/meso/macro scale under ultraâ€‘high temperature and pressure (UTP) conditions were developed employing the flow driven poreâ€‘network crack (FDPNC) model under multiple temporalâ€“spatial scales and the hybrid hypersingular integral equationâ€‘lattice Boltzmann method (HHIEâ€‘LBM).
Findings could aid in the development of better technologies for hydraulic fracturing and other fluid extraction techniques from the earth.
Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are important and useful in fields from farming to engineering.
WASHINGTON, Oct. 2 /PRNewswire-USNewswire/ -- The Honorable Jo-Ellen Darcy was sworn in today as the U.S. Army's 11th Assistant Secretary of the Army for Civil Works (ASA(CW)) in a Pentagon ceremony.
By Andy Franks LONG BEACH - Your description of Tuesday's earthquake might be different from your friend's across town, but for a good reason: Geologic surveys show that some parts of Long Beach are more sensitive to ground motion.
By Keener, H M Wicks, M H; Skora, J A VOLUMETRIC IMPORTANCE Study develops consistent methodology for accurately measuring volumes of unprocessed and processed materials at yard trimmings composting facilities.
By Munch, E Franco, J; Deville, S; Hunger, P; Saiz, E; Tomsia, A P This work compares Two novel techniques for the fabrication of ceramic scaffolds for bone tissue engineering with complex porosity: robocasting and freeze casting.
By Singha, Kamini ABSTRACT The concepts of total stress, effective stress, and fluid pressure are important to understanding where water comes from when producing water from a confined aquifer system.
Creating artificial seismic waves, similar to those that occur during an earthquake, could help squeeze more oil from natural reservoirs, scientists said on Wednesday.
