摘要:

The Bacbo delta is situated in the North of Vietnam covering an area of 15 000 km2. Mainly the Red River has caused the delta. Transgressions happened between Holocene and Pleistocene with clays and marls. By means of isotope-hydrogeological investigation

摘要:

Recharge areas in hard rocks of the margin of the Mygdonias-Basin (Greece) with the origin of thermal waters (max. 50°C) are assumed. Environmental isotopes,3H, D,18O.13C,34S are supporting a concept of recharging normal temperated water along the northern margin of the basin, especially in the cross-area of tectonic faults.

摘要:

The isotopic composition (D,18O,87Sr,3He) of thermal and mineral waters of Mongolia is discussed. The Sr-isotope ratio depends on the rock's contact. Near the Chubsugul-lake3He-/4He-values are high. A certain similarity between the waters of Mongolia and those of East Siberia can be derived from the obtained data.

摘要:

During hydraulic dumping of ashes at a sludge bed of the power plant at Mělnik (north of Prague), new springs originated which wetted houses and properties at the small village of Podvlci. The sludge bed as well as the village lie at the southwestern margin of the alluvial plain of the Labe (Elbe) River at the foot of a slope built of Cretaceous sedimentary rocks. By analyzing the concentrations of radiocarbon and tritium, it was possible to determine the origin of the water and the ratio of the modern and original groundwater in the new springs in the surroundings of the sludge bed. To substitute the present dump the operation of which should be stopped, establishing of a new one has been proposed within the alluvial plain. By means of stable isotopes and radionuclides, the relations between the groundwater in the Quaternary sediments and in the underlying Middle Turonian confined aquifer were studied, because changes in the hydrogeological regime have to be expected due to the operation of the proposed new sludge bed.

摘要:

The results of continuous radon measurements in soil air and the water of a mineral spring at Bad Brambach are presented. They are discussed in connection with meteorological, hydrological parameters, and seismic events with magnitudes <3. The atmospheric pressure (especially pressure gradient), the temperature, and the groundwater level gradient have a significant influence onto radon activity of soil air.

摘要:

Bottom sediments of two lakes in Bulgaria (Lake Iskar, Lake Pantcharevo) are investigated concerning the90Sr-content. The interpretation of the data shows that this region has been more affected by the Chernobyl accident than comparable soils in Japan.
