This paper describes the gestation of the hydrologiccycle as a distinct entity in the English-speaking hydrological tradition and explains how and why it attained a specific form in the United States in the 1930s. This modern hydrologiccycle
of people. To the extent that it structures an understanding of water that is increasingly at odds with social and hydrological experience, the modern hydrologiccycle can be considered unsustainable.
The ways of incorporation of hydrologiccycle elements into the dynamic-stochastic heat and water exchange climate model are considered. Such approach enables to identify the main sources of precipitation climatologic variability.

The land-ocean ratio, periodical alternation of the epochs of orogenesis and peneplanation, time-space changes of solar influx determined the periodical changes of the global hydrologicalcycles with development of the continental glaciations
and permafrosts, or large pluvial epochs of general warming. At present an ever greater impact on the changes of the hydrologicalcycle is produced by human activities and the recent climatic warming.

In order to evaluate the effect of the deposition of strong mineral acids into river basins with low capacity of acid neutralization, the AA. want to compare the behaviour of Al species within the hydrologicalcycle, e.g. during their passage

This article examines the potential sensivity of water ressources in the UK to climatic change as exemplified by the 1988-92 drought. The representation of hydrological processes at three distinct model scales is then discussed with reference
to global hydrology, regional downscaling and catchment-scale responses. A final section speculates on future directions of research for an emerging greenhouse hydrology.

In short review paper, the A. discusses the role of studies on changes in the continental water cycle for a better understanding of temporal change in biomass production and carbon storage. All calculations made for the late Pleistocene and Holocene
should take into consideration not only the subsequent rises in temperature, precipitation and carbon storage, but also secondary hydrologic variations, which differ spatially due to climatic zonation as well as to geography, lithology and other factors
. To a large extend, the present-day picture of the water cycle and biomass production is tranformated by man. - (DG)
Les deux grands thèmes du symposium ont donné lieu à 2 volumes de communications (95 pour le thème I, 55 pour le thème II). A l'intérieur du thème I, les exposés sont regroupés selon les chapitres suivants : 1. Improved methods of hydrological
measurements. 2. Quantitative and qualitative water cycle aspects in heterogene basins. Le thème II se répartit en 2 grandes parties : 1. Impact des réservoirs artificiels sur l'équilibre écologique. 2. Run off processes and slope development. - (HV)

Hydrology is an established twentieth-century environmental science, whose content is necessarily interdisciplinary (biology, physics, chemistry, geomorphology and, increasingly, the social environmental sciences such as planning, economics
