(1988)Hydrogeologic indications of recent movements of the Earth's crust in two regions of North Tian-Shan have been studied. Comparison of ground-water level changes and variations of recent vertical movements according to ...
-
(2003)This study reviews the up-to-date hydrogeological contribution of the new, geophysical magnetic resonance sounding (MRS) method and presents new interpretation ideas and potential regarding various hydrogeological applications. ...
-
(1988)In November 1966, geologists discovered a large anticlinal fold in the vicinity of the Sol'-Iletskiy swell which overlaps the northern flank of the Caspian Basin. This tectonic feature subsequently became widely known, ...
-
(2019)This paper is concerned with the main stages in the setting-up and technical development of a system specializing in physical and chemical parameters of groundwater at a network of wells and springs in the Petropavlovsk ...
-
(2001)The hydrologic uncertainty processor (HUP) is a component of the Bayesian forecasting system (BFS) which produces a short-term probabilistic river stage forecast (PRSF) based on a probabilistic quantitative precipitation ...
-
(PANGAEA, 2018-10-18)This study investigates a variety of lakes of different origin in the Siberian Lena River delta for lake hydrological, hydrochemical, and morpho- metric characteristics. The results are based on in-situ field measurements ...
-
(2001)Good quality hydrologic data are required to develop and calibrate simulation models, which are often used to plan, design and upgrade urban stormwater drainage systems. These good quality data can be obtained from a ...
-
(2004)Neptunium is one of the few radioactive elements that are of great concern in the disposal of nuclear wastes in the geological repository, due to its hazards and the long half-life of the isotope, 237Np (t 1/2 = 2.14 × 106 ...
-
(2003)The hydrothermal transformation of 2-line ferrihydrite into hematite proceeds slowly if a sufficient quantity of some strongly adsorbing ligand. such as phosphate or citrate, is sorbed on the starting product. In this work, ...
-
(1989)Hydromagnetic diagnosis, a method of determining the status of the periterrestrial medium from observations of hydromagnetic fields originating in space, and magnetotelluric sounding of the crust, a method of geological ...
-
(2003)Earth's porous crust and the fluids within it are intimately linked through their mechanical effects on each other. This paper presents an overview of such "hydromechanical" coupling and examines current understanding of ...
-
(1987)A coastal upwelling is produced by long-shore winds that generate drift currents If the Coriolis force deflects these away from shore, then the ebb flow of surface waters results in an upwelling. The authors use as an ...
-
(1999)Measurements in Baikal taken in 1993-97 have revealed some regularities in regime and turnover of silicon in different parts of the lake. Vertical distribution of silicon is controlled by advection of either low-Si (limnic) ...
-
(2003)During the past 5 million years significant changes have taken place in the Lake Baikal ecosystem. The climate changed from subtropical, with average annual air temperatures (T air) of 15–10 °C, to a moderate one with T ...
-
(2004)The major organic component of carbonaceous chondrites is a solvent-insoluble, high molecular weight macromolecular material that constitutes at least 70% of the total organic content in these meteorites. Analytical pyrolysis ...
-
(1992)The model of hydroseismicity relates variations of the hydrological state of the earth's crust to seismicity through the weakening of rocks by fluids and the transfer of stresses from hydrologically affected regions into ...
-
(2003)The solubility of chalcocite has been measured over the temperature range 35-95°C at pH 6.5-7.5 in aqueous hydrosulfide solutions in order to determine the stability constants of the Cu(HS)2- complex. A heated flow-through ...
-
(2001)Carbonate hydrotalcites (HTls) were prepared by coprecipitation of metal nitrate salts and Na2CO3. The structural features of noncalcined, calcined and reconstructed materials were characterized by XRD, 27Al MAS NMR, AAS ...
-
(1998)This paper sums up the results of previous studies of the thermal springs in the Akademii Nauk caldera, and presents the results of investigations on the condition of the springs as at July 1996, namely, a description of ...
-
(1995)Compositions of hydrothermal chlorite and fine-grained white mica from the inner and outer alteration halos in the Koongarra U deposit were analyzed by electron microprobe and analytical electron microscopy. Analyses show ...
