contain thick columns of recent river deposits and the deposits in and around Burdwan are saturated with shallow groundwater. A relook into the velocity– depth section in light of some specific indications in the record sections of SPs 5, 6, 7 and 8 suggests probable presence of hidden faults (F2′ F3′ and F3) below the basement in the zone between Sonamukhi–Khandaghosh and Khandaghosh– Burdwan....

Geostatistics and geographic information system (GIS) were performed to characterize the spatial variability of soil water characteristics in western semiarid area of Heilongjiang Province and delineate the spatial distributions of the variables. On the basis of data source spatial distribution and professional knowledge, the study site was divided into four irrigation management zones. Then st...

Capillary fringes are highly dynamic and periodically changing zones at the interface between the water-saturated aquifer and the unsaturated zone. As a consequence, we observe steep gradients in terms of hydraulic state variables, biogeochemical conditions, and thus, biological activity (Berkowitz et al., 2004). With fluctuations of the groundwater table, this reactive zone moves dynamically a...

[1] This paper analyzes slip on a fluid-infiltrated dilatant fault for imposed (tectonic) strain rates much slower than the rate of fluid exchange between the gouge zone and the surroundings and for exchange of heat slower than of fluid, typical of interseismic or most laboratory loading conditions. The limiting solution, corresponding to the infinitely rapid drainage rate, developed in the com...

Abstract: In this paper, a dead zone based model of saturation phenomenon is proposed, which enables to model diverse kinds of saturation, such as hard limitted and soft limitted ones. Due to the use of a linear in parameter approach, the proposed model is consistent with the available adaptive control techniques in the literature. Besides, based on the proposed model, an adaptive controller is...

GSFLOW is a new U.S. Geological Survey model for simulating ground-water/surface-water interactions. GSFLOW couples PRMS (the Precipitation Runoff Modeling System) to MODFLOW (the Modular Ground-Water Model) with modules for simulating flow and storage in unsaturated-zones, lakes, and streams. GSFLOW simulates infiltration, runoff generation, and lateral flow in temporarily saturated material (...

The aim of this research was to investigate the influence of metallurgy on the corrosion behaviour of separate weld zone (WZ) and parent plate (PP) regions of X65 pipeline steel in a solution of deionised water saturated with CO2, at two different temperatures (55 °C and 80 °C) and at initial pH~4.0. In addition, a non-electrochemical immersion experiment was also performed at 80 °C in CO2, on ...

Field and laboratory observations indicate that at seismic slip rates most shearing is confined to a very narrow zone, just a few tens to hundreds of microns wide, and sometimes as small as a few microns. Rice et al. [2013] analyzed the stability of uniform shear in a fluid-saturated gouge material. They considered two distinct mechanisms to limit localization to a finite thickness zone, rate-s...

The distribution and composition of endogenous lipids in articular cartilage and transport of exogenous fatty acids have been investigated on a microscopic scale in fresh bovine articular cartilage. To investigate the distribution and composition of the endogenous lipids, hyperspectral Raman maps were taken of chondrocytes and their surrounding matrix in both the deep and superficial zones. The...
