The residence time of the solutes was defined by the ratio of length of soil column to
pore-water velocity and multiplied by R.
But 1970-81 provided Ross's classical treatment of disturbance to permafrost terrain (1970); segregation as the origin of massive ice (1971); preservation of permafrost and ground ice beneath the Laurentide ice sheet (1972); the origin of offshore permafrost (1972); the development of pingos from
pore-water expulsion (1973); the influence of snow cover on ground temperatures (1974); the characteristics of thermal contraction cracking (1974); experimental demonstration of pingo growth (1977); identification of an early-Holocene thaw unconformity (1978); the origin of hummocks (1980); and plug-like flow in solifluction (1981).
The dissipation of
pore-water pressure in the embankment is largely influenced by the permeability and the storage characteristic of the embankment materials.
Sediment diatom assemblages and composition of
pore-water dissolved organic matter reflect recent eutrophication history of Lake Peipsi (Estonia/Russia).
The analysis can use either the Darcy velocity, q, or the
pore-water velocity, v = q/[theta]; we prefer the latter because (i) the resulting equations are simpler, and (ii) we use v in the later analysis of our experiments with CXTFIT 2.
Although the initial pH of the cement
pore-water varied between 13 and 14, during the tests, the pH of the effluents reached a maximum of 11.
For a saturated sand under undrained conditions, the tendency for volume reduction during each cycle of loading results in a corresponding progressive increase in
pore-water pressure.
Pore waters were separated from sediments by centrifugation, and the concentration of adsorbed ammonium was determined as the difference between total- and
pore-water ammonium.
PORE-WATER PRESSURE AND WATER TABLE VARIATION DURING EARTHQUAKE SIMULATIONS.
Soil nitrate concentrations were calculated on both a soil (mg/kg dry soil) and
pore-water basis [(mg/kg dry soil)/gravimetric water content].
During each field season, I measured
pore-water salinity at 15-cm depth in the rhizosphere of each experimental tree.

pore-water with sufficient spatial and temporal resolution.
