In shallow groundwater agricultural fields, water exchanges between groundwater and soil water happen frequently and intensively. This paper analyzes the regime of subsurface water during the growing period of winter wheat from October 1998 to June
1999 in Yucheng area. The results showed that a significant proportion of field evapotranspiration was supplied by groundwater evaporation, whereas the role of groundwater evaporation was not considered during irrigation, leading to soil water
percolation into groundwater. In order to improve water use efficiency of crops, some measures were put forward in the paper.

This paper, based on a semi-conceptual hydrological model, analyses global warming effects on the Hanjiang River hydrological regimes and water resources, including soil moisture, evaporation, runoff and the transferable water quantity from
the Danjiangkou Reservoir according to Middle Route of China's South-to-North Water Transfer Project.

The paper deals with the problem of the investigation on river regime. The river regime is understood as some type and time structure of hydrological phenomena in the annual cycle. It has been accepted that hydrological periods are means
of the river regime investigations as well as the basis for its characteristics. 0n the example of the Prosna river were presented the usefulness of the described theoretical model and the methods for the separation of those periods in order to investigate
Stability of clay aggregates as a function of waterregimes in Impact of water and external forces on soil structure. Selected papers of the 1st Workshop on soilphysics and soilmechanics, Hannover 1986.
The experiments confirm the results that stability of clay aggregates is not only a matter of water content. Stability of clay aggregates is a function of their waterregime, which is the result of the amount of water and the corresponding pressure.

An experimental computational method is proposed for determining the irrigation regime of agricultural crops and losses of irrigation water by infiltration beyond the root zone of the soil, based on information on soil moisture suction or soil
. A relationship is proposed approximating the curve of soil water intake. Results of calculations of the irrigation regime of cotton by the proposed method showed that the irrigation rate and the rate of infiltration of irrigation water decrease as the soils
become finer in texture and the water table rises.

environmental problems recognized were: waterregime, intensive sedimentation, enhanced water eutrophycation and toxic cyanobacterial blooms. Observed environmental problems and proposed solutions in this case including different technical and chemical methods
could also be applied to other artificial water bodies in this region. - (IKR)

The Żarnowska bog is located in a south-eastern part of the Słowiński National Park and remains an example of high peatbogs of the Baltic type, very rare in Poland. Its natural regime was disturbed by human activities as early as in the 18th century
. The paper examines water conditions characteristics of and threats to the peatbog. It presents the steps taken by the Słowiński National Park in order to reconstruct the natural circulation and water supplies and stop degradation of the area’s natural
