-water recharge and to simulate ground-water flow and solute transport in a warmer, 2xCO2 climate. In addition, it outlines the development of a methodology to quantify the effects of climate change and of changes in ground-water use by population growth
This article summarizes the theory of climate change and the relationship of climate-change forcing to hydrologic and aquifer processes. It focuses on regional aquifer systems and on the methods to link large-scale climate-change processes to ground

The article presents and compares current views on the development of sorted patterned-grounds in the periglacial zone. The theories can be divided into 8 groups, which assume : 1) convection and/or circulation of the ground en masse ; 2
programming to the problem of the optimal joint development and supply of surface water and groundwater. Separately, a mathematical groundwater basin model of the region is linked to the linear programming model to study the groundwater level variations
The publication presents a methodology developed for planning the optimum supply of irrigation water for agricultural practices in Varamin Plain, Iran. As a mathematical simulation technique, optimization method is used by applying the linear
Vplyv podzemnych vôd na krajinnu strukturu Ondavskej roviny Influence of groundwaters on the landscape structure of the Ondavska rovina plain
Analys of the regime factors solving the groundwater and recharge problems. The level of hydromorphy is applicated by means of ball method on the study area. - (MS)
Beziehungen zwischen Grundwasserstand und Bodenwassergehalt in verschiedenen Sanden. (Relations between ground-water level and moisture content in various sandy soils)
It was found out that the moisture equivalent is reached at about 40, 60and90cm above ground-water level in coarse, medium and fine sands, respectively. Threshold values were determined in the range of which the ground-water level may very and yet

of the country is described with special reference to the interests of agriculture and reservoir capacities in the various regions. The second half of the paper focuses on the contamination problems of surface and groundwater bodies. - (JS)
This paper gives a short overview about the hydrological conditions of Hungary with special attention to water budget and water quality problems. It begins with an overview to what extent Hungary is dependent on water, then the water budget
By combination of century-old experiences with open dug wells and surface reservoirs with scientific techniques of groundwater prospecting and supply of energy, evolutionarily an alternative water management system can be developed
. This will consist of surface reservoirs for groundwater recharge, natural fractures and dykes for water transport, modern exploration techniques for their identification and traditional open dug wells as water sources. (L'A.).

Using the area of Yabulai Mpountains, as an example, this paper provides insight into the chemistry of ground and surface water in western Inner Mongolia. The recharge mechanisms of groundwater and the hydrological evolution in this region during
Groundwater : a parameter in determining land use pattern in Siwana region, Western Rajasthan
This paper aims to identify groundwater potential zones and remote sensing methods to demarcate various future land use units, through geo-electrical investigation conducted in a close grid pattern around Siwana region. Secondary data are used

In relation to population, Romania's water supplies are quite modest. They are essentialy provided by the rivers. The factors responsible for both maximum and minimum runoff are discussed and particular reference is made to the floods of 1970. Load
and turbidity levels are also discussed. Underground water sources are described and a review of demand gives particular attention to hydroelectricity and water transport.

in areas of considerable tectonic disturbance. The geochemistry of the ground ice is the result of cryogenic processes that cause salt differentiation during water freezing, together with natural solute concentration and cryogenic mineral formation.
Mesuring streambank erosion due to groundwater seepage : correlation to bank pore water pressure, precipitation and stream stage
The aim of this research was to demonstrate the importance of streambank composition and stratigraphy in controlling seepage flow and to quantify correlation of seepage flow/erosion with precipitation, stream stage and soil pore water pressure
