of people. To the extent that it structures an understanding of water that is increasingly at odds with social and hydrological experience, the modern hydrologic cycle can be considered unsustainable.
Assessment of the river habitat quality within European Water Framework Directive : application to different catchments in Czechia
the state of the watercourse in the context of the EC Water Framework Directive. The goal of this research was to assess the ecohydromorphological state of selected catchments in Czechia, representing varied relief types, and at the same, representing

Hydrogeographical methods of estimating nonmeasured discharges presented in this article are used to estimate the mean discharges in a period measured on water courses which are not directly included in the network of gauging stations. This article
provides a theoretical starting point and methodological procedures used to estimate non-measured discharges on Slovenian water courses and draws attention to some limitations to which we have been exposed. - (IKR)

The study is conceived to find a balanced approach to the reclamation processes of the spoil heaps in the former coal mining area of Pécs and of a slurry reservoir. The authors emphasize the relationship between the quality of surface waters
and land use, because the relative impact of the growth of vegetation on the water quality are yet to be examined and quantified. - (AM)
The German water economy has indisputably high quality and provision standards at its disposal also in an international comparison. It can be expected that a sufficient water supply and sewage disposal which also be secured in all sub-areas

Much of the recent research has focused on surface water. A compendium of water-balance research from 39 high-latitude catchments reveals the strengths and limitations of the available results, most of which are restricted to only a few years
Runoff and sediment lost due to water erosion were recorded for 36 plots with varying types of vegetative cover located on sloping gypsiferous fields in the South of Madrid. Vegetative cover above 40% is capable of dissipating the relationship
Above-ground earthworm casts affect water runoff and soil erosion in Northern Vietnam
The AA. investigated the effects of Amynthas khami, an anecic species producing above-ground casts of prominent size, on water infiltration and soil detachment along a land-use intensification gradient. Two scales of studies were considered
: at the structure scale (cm2), a water runoff simulation was used to differentiate the effects of casts, free biogenic aggregates that previously belong to casts, and free physicogenic aggregates; at the station levels, 1-m2 plots were used to determine runoff
