-
(2003)In this paper an attempt is made to present a distributed physiographic conceptual model that uses the principles of flow continuity and momentum. For this purpose, the watershed under study is divided into subwatersheds ...
-
(EDP Sciences, 2019)Geochemical conditions of the formation of various minerals were studied within the oligotrophic pine-shrub and sphagnum peat bog. It was shown that at least two complex barriers function within the peat deposit. These ...
-
(2004)The fast marching method (FMM) is a grid based numerical scheme for tracking the evolution of monotonically advancing interfaces via finite-difference solution of the eikonal equation. Like many other grid based techniques, ...
-
(2013)The work presents a review of natural-science representations on the rotary motion of matter and its piecewise structure. Development of dense GPS-networks allowed to experimentally confirm the concept of block structures ...
-
(2001)N-type earthquakes sometimes occur before the eruption of andesitic volcanoes, but their source mechanism has not been understood well. Their waveforms have stationary periods and decay slowly resembling to damped oscillation. ...
-
(2003)A process-based facies model for asymmetric wave-influenced deltas predicts significant river-borne muds with potentially lower quality reservoir facies in prodelta and downdrift areas, and better quality sand in updrift ...
-
(2003)A new formulation is presented to describe both the wavefield and the static coseismic deformation in depth-dependent elastic models generated by an a priori prescribed plane dislocation seismic source of finite dimensions, ...
-
WAVEFIELD EXTRAPOLATION AND AMPLITUDE-VARIATION-WITH-ANGLE MIGRATION IN HIGHLY DISCONTINUOUS MEDIA (2003)Current macromodel-based one-way wavefield extrapolation ignores the practical highly discontinuous character of rock formations. The main effects of this highly discontinuous behaviour on transmitted wavefields are ...
-
(2001)Wavefront healing is a ubiquitous diffraction phenomenon that affects cross-correlation traveltime measurements, whenever the scale of the 3-D variations in wave speed is comparable to the characteristic wavelength of the ...
-
(2004)Multiresolution wavelet analysis of self-potential signals and rainfall levels is performed for extracting fluctua- tions in electrical signals, which might be addressed to meteorological variability. In the time-scale ...
-
(2000)We performed spectral analysis of the record of relative geomagnetic paleointensity obtained at ODP Site 983, covering the time interval 0-1.1 Ma. The results confirm the presence of significant power at frequencies ...
-
(2003)Temporal characteristics of secular variations (SV) over the last hundred of years are studied using the wavelet transformation, providing estimates of dispersion and energy parameters of the process analyzed. The presence ...
-
(2005)Wavelet coherence analysis is defined and used to analyze the relationships between Length-Of-Day (LOD) variations and El Niño-Southern Oscillation (ENSO) on interannual scales. Using the newest observation data, this study ...
-
(2002)Magma mixing is a common process and yet the rates, kinematics and numbers of events are difficult to establish. One expression of mixing is the major, trace element, and isotopic zoning in crystals, which provides a ...
-
(2001)We have addressed the problem of subduction initiation with a solid-mechanical and fluid-dynamical approach, using a finite-element method. The setup has been extended by a rate-sensitive coupling at the bottom of a ...
-
(2003)Explicit equations for approximate linearized reflection-transmission coefficients at a generally oriented weak-contrast interface separating two generally and independently anisotropic media are presented. The equations ...
-
(2001)There are many observations in naturally deformed rocks on the effects of mineral reactions on deformation, but few experimental data. In order to study the effects of chemical disequilibrium on deformation we have ...
-
(2001)Weathering profiles developed on the top surface of a bentonite (containing Al-Mg montmorillonite) and a K-bentonite (containing mixed-layer illite-smectite (I-S)) under Central European temperate conditions were studied ...
-
(2002)This paper characterizes the weathering products of the two-mica Oporto granite in terms of its mineralogical, chemical, geotechnical and physical properties. This information is used to identify a physical property that ...
-
(2004)Weathering occurs over a wide range of scales. To link features through these scales is a major challenge for interdisciplinary weathering studies. Fractal approach seems to be specially useful for this purpose. We introduce ...
