(2001)We analyze the dynamics (amplitudes and phase distortions) of seismic waves as they propagate along the ray. Our analysis is performed via a ray series approximation in the time domain. That is, we concentrate on characterizing ...
-
(2006)In this study the Penman-Monteith reference evapotranspiration, pan evaporation measured by a 20 cm pan, and pan coefficient, i.e., the ratio of Penman-Monteith evapotranspiration to pan evaporation, at 150 meteorological ...
-
(2002)Ferric minerals are commonly found in soils and sediments, especially in tropical areas. Previous studies have shown that ferric minerals in sediments can cause underestimation of acid-volatile sulfides (AVS). No reliable ...
-
(2002)Potential matrix effects in the sulfur isotopic analysis of whole rocks by elemental analyzer-continuous-flow isotope ratio mass spectrometry (EA-CFIRMS) have been investigated by measuring mixtures of a well-calibrated ...
-
(2002)The term hyperconcentrated flow refers to intermediate states between debris flows and fluid flows, where fluid turbulence remains an important dispersal mechanism of clastic particles. Whereas the end-member flows are ...
-
(1987)Earth scientists have long believed that the present-day volume of the hydrosphere has been stable for a long time and that its changes in the present and future will be extremely small. The earth's water is believed to ...

ANALYSIS OF THE MOBILIZATION OF SOLID LOADS AND HEAVY METALS IN RUNOFF WATERS FROM GRANITE QUARRIES (2006)The cutting operations of dimension stone at quarries produce a large amount of fines that, in turn, cause a negative environmental impact over local surface waters. This article presents a detailed analysis of the mobilized ...
-
(2004)In the inversion of observed waveforms to obtain the earthquake source faulting process some uncertain factors may influence the reliability of the results. Several numerical tests have been analysed in this paper in order ...
-
(2002)Most studies of nearshore hydrodynamics, sediment transport, and morphology focus on bathymetric variability within a narrow band of spatial and temporal scales. Typically, these studies rely on bathymetry estimates derived ...
-
(2002)We have developed a method for determining paleoelevations of highland areas on the basis of the vesicularity of lava flows. Vesicular lavas preserve a record of paleopressure at the time and place of emplacement because ...
-
(2002)Part (I) of this study presented field and laboratory experimental data on soil characteristics and hydraulic parameters that are related to water infiltration in rice paddy fields. Part (II) includes a series of numerical ...
-
(2004)The stability problem of a rock slope containing a wedge resting on two intersecting discontinuities is of great interest in rock slope engineering. It is a statistically indeterminate problem with two extra unknowns ...
-
(2006)Mercury is a pollutant of concern due to its toxic and bioaccumulative properties. Studies on the distribution and hazard of mercury in the environment are mainly focused on its forms, toxicity and the environment standard, ...
-
(2006)Point and line singularities are superposed with incident unidirectional saturated and unsaturated flows. The resulting isobars of 3D Laplacian or advective dispersion equation fields model either seepage face dimples and ...
-
(2001)Methods of prevention of sudden outbursts have been considered. It has been shown that preliminary degassing of coal seams with the use of hydraulic separation of them is efficient method. Mathematical model of process of ...
-
(2001)Real rock is non-uniform solid body. Non-uniformity of the rock is determined by presence of pores, microcracks etc. Recurrence formulae have been offered for probabilities, describing simulation model of kinetic process ...
-
(2001)Some plates deform across zones that are many hundreds to thousands of kilometres wide, much broader than traditional boundaries such as mid-ocean ridges, deep-sea trenches and oceanic transform faults, across which most ...
-
(2002)We investigate the analytic signal method and its applicability in obtaining source locations of compact environmental magnetic objects. Previous investigations have shown that, for two-dimensional magnetic sources, the ...
-
(2002)One-dimensional analytical porosity-weighted solutions of the dual-porosity model are derived, providing insights on how to relate exchange and storage coefficients to the volumetric density of the high-permeability medium. ...
