During recent years, the quantitative description of the water fluxes and the coupled transport of physical and chemical matter in the landscape has become steadily more and more important. The reasons for this are an increasing public awareness about the possible impacts of changes of land use, land cover, and of changes in regional and global climatic conditions together with a need for sound, multi-objective management of large river basins. The investigation areas of concern are usually much larger in extent than a typically sized hydrological investigation catchment. The tools primarily used in the quantification of the hydrological fluxes at the large scale are the so-called large-scale hydrological models. These models are comparatively new and still at the stage of development and improvement.

The mentioned need for advanced large-scale hydrological models provided the reason for inviting scientists from German-speaking countries with experience in large-scale hydrological and hydro-meteorological models to exchange and discuss their modelling concepts and to identify reasearch needs. The workshop was held at the Potsdam Institute for Climate Impact Research (PIK) on 15 and 16 December 1997, and was jointly organised by PIK, the University of Potsdam and the Centre for Agriculture and Land Use Research (ZALF). The workshop was attended by over 40 scientists, of whom 19 gave a presentation.

The proceedings of the workshop are contained in this PIK Report. The 20 articles can be divided into 4 groups:

• The first seven articles are mainly concerned with the quantitative aspects of large-scale hydrology and the possibilities of modelling these.

• Articles 8 to 14 are mainly about the quality aspects of large-scale hydrology and the possibilities of modelling these.

• Articles 15 to 19 cover the field of coupling large-scale hydrological models with meso-scale meteorological models, though article 15 does not fit exactly into this category.

• The last article summarises the presentations and the discussion at the workshop.
