Earthquake-induced soil liquefaction can generate excessive damage to building structures due significant reduction in effective stress. With increasing urbanisation and population growth, the performance of closely spaced buildings, such as those towns cities, is greater concern where structure–soil–structure interaction (SSSI) may occur conjunction with full or partial liquefaction. This stud...

Field and laboratory analyses of soils on 11 well-dated fluvisil terraces spanning the past 0.5 m.y. demonstrate that a threshold governs changes in several morphological and chemical characteristics of increasingly older soils. Correlations with respect to time among iron species, soil morphology, and soil silt and clay demonstrate that the chronosequence at Cajon Pass reflects primarily an ev...

The ability to determine inactivation rates of Cryptosporidium parvum oocysts in environmental samples is critical for assessing the public health hazard of this gastrointestinal parasite in watersheds. We compared a dye permeability assay, which tests the differential uptake of the fluorochromes 4'-6-diamidino-2-phenylindole (DAPI) and propidium iodide (PI) by the oocysts (A. T. Campbell, L. J...

grazing management plays an important role in the continuous and economicutilization of pastures. proper grazing management is a main factor for the accumulation ofplant litter which reduces soil erosion and increase the soil permeability to keep moremoisture in the soil. in current study, the effect of three different grazing intensities (low,moderate and high) along with the grazing gradient ...

In this paper, the slipping friction is considered in the problem of a progressive wave of real fluids propagating over a permeable bottom.In the interface of soil and fluid, the “no-slip” condition is relaxed and a sliding friction coefficient is introduced. Thus, the slipping effect and the permeability of the bottom on the velocity near the seabed can be studied. The results indicate that th...

Slow infiltration rates constrain effective and economical irrigation in some sandy loam soils in California. Polyacrylamide (PAM) has increased soil infiltration in some areas, especially in soils high in clay or silt. Field trials near Fresno, CA, with PAM failed to show improved infiltration. Laboratory experiments were conducted to investigate PAM effect on infiltration of various quality w...
