VW piezometers are used to monitor pore-water
pressure in the borehole.
Nevertheless, REEs can get incorporated directly from the seawater during early diagenesis, with little or no fractionation, and therefore have potential to reflect bottom and pore-water
chemistry of a given palaeobasin (see Wright et al.
The lag of the phreatic line depends on factors such as: permeability of soils, drawdown rate, drawdown ratio and slope gradient during rapid drawdown, the stabilizing effect of the water on the upstream face is lost, but the pore-water
pressures within the embankment may remain high.
2008), within the datalogger or meter, to assess the soil pore-water
electrical conductivity ([[sigma].
Each plot also includes a subsurface drain that can be used to control groundwater in the near-streambank vadose zone, supplementing existing research at OSU on the role of pore-water
pressures and groundwater processes on stream-bank erosion anci failure.
2007), and in the chemical composition of pore-water
pigments and dissolved organic matter (Leeben et al.
1995) to analyse the net effect of these 2 disparate processes in terms of 'effective' coefficients of hydrodynamic dispersion and 'effective' retardation factors for a wide range of pore-water
velocities, particle and column sizes, and density differences.
For example, much if not most, pore-water
flow at very shallow depths is facilitated by tidal pumping in marine settings, giving way to compaction with increasing depth.
Seed and Booker (1977) approach for pore-water
pressure generation and dissipation is applied, with some modifications for evaluating the densification effect of GPs, incorporating modifications in coefficients of volume change and permeability, to the analysis of columnar gravel drains under a variety of earthquake conditions.
PRESSURE AND WATER TABLE VARIATION DURING EARTHQUAKE SIMULATIONS.
Winter-season Drilling Is Preferable In Order To Minimize Evaporation From The Vadose-zone Cores That Will Be Collected For Pore-water
1998) compared different approaches to calculate statistics of the solute travel time and displacement based on spatial covariance functions of the pore-water
