Significant deviations from standard Boltzmann scaling, which corresponds to normal or Fickian diffusion, have been observed in the literature for water movement porous media. However, as demonstrated by various researchers, widely used conventional Richards equation cannot mimic anomalous diffusion and ignores features of natural soils are heterogeneous. Within this framework, governing equati...

A water budget model is proposed to estimate the infiltration, runoff, evapotranspiration and recharge in vadose zone and apply to a case study. The instantaneous redistribution of infiltrated water is assumed to be uniform and a linear relationship between evapotranspiration and effective saturation is imposed. Infiltration is described by Philip’s solution in conjunction with the time compres...

BACKGROUND Randomized trials evaluating efficacy of local infiltration analgesia (LIA) have been published but many of these lack standardized analgesics. There is a paucity of reports on the effects of LIA on functional capability and quality of life. METHODS 56 patients undergoing unilateral total knee arthroplasty (TKA) were randomized into 2 groups in this placebo-controlled study with 12...

Cover crops (CCs) are known to influence water infiltration just prior termination, but their effects on over time less known. This study investigated the of CCs in situ CC termination (during April) and again 2 mo after June). The multi-species mixture used included hairy vetch (Vicia villosa Roth.), crimson clover (Trifolium incarnatum L.), winter wheat (Triticum aestivum peas (Lathyrus hirsu...

A hallmark of aging-related organ deterioration is a dysregulated immune response characterized by pathologic leukocyte infiltration of affected tissues. Mechanisms and genes involved are as yet unknown. To identify genes associated with aging-related renal infiltration, we analyzed kidneys from aged mice (≥20 strains) for infiltrating leukocytes followed by Haplotype Association Mapping (HAM) ...

Incubating salmonid eggs in streambeds are often threatened by deposition of fine sediment within the gravel. To relate sedimentation of spawning gravel beds to sediment transport, infiltration of fine sediment (<2 mm in diameter) into clean gravel beds, bed material size distributions, scour-fill depths, and sediment transport during 10 storm flow events were measured in three streams of north...

Yellow River sediment is the potential resource for saline–sodic soil reclamation. Experiments of one-dimensional columns were conducted to investigate upward and downward water transportation characteristics mixed with different addition (0, 10, 20 kg/m2 in top cm layer). The saturated hydraulic conductivity, ratio macroporosity, cumulative capillary adsorption infiltration rate all increased ...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

Abstract To cope with water scarcity in drylands, stormwater is often collected surface basins and subsequently stored shallow aquifers via infiltration. These harvesting systems are accompanied by high evaporation rates hygiene problems. This commonly a consequence of low infiltration rates, which caused clogging layers that form on top the soil profile presence thick vadose zone. The present ...
