Only in well-defined small basins with high-quality measurements can the complexities of combined physical, chemical and biological processes be adequately investigated. Small hydrological research basins provide interdisciplinary observatories, thus contributing to the study of the impact of environmental changes and to developing strategies for water and land-use management under such change.
This volume, the Proceedings of the Workshop held at Goslar-Hahnenklee, Germany, in spring 2009 focuses on:
  • Presently operational small research basins
  • Fundamental hydrological research results drawn from small basins
  • Hydrological processes
  • Importance of small basindata and results for hydrological modelling
and includes the Braunschweig Declaration on: The need for a global network of long-term small hydrological research basins.

AbstractIt is shown that milestones in the development of hydrological small basin research are facilitated by the launching of the international programmes IHD, IHP, FRIEND and ERB. The history, main strategies and objectives of these programmes are displayed, and their contributions to the progress in hydrological knowledge and capacity development are outlined. High value is attributed to the documentation of existing study basins. Easily accessible inventories and the networking among basin operators and scientists are shown to be a decisive step towards the efficient use of the acquired knowledge.

AbstractThe history of the Lange Bramke catchment, the longest operated small hydrological research basin in Germany, is summarized on the occasion of its 60th anniversary with a focus on the research history, the main research projects run in the catchment and their protagonists. The major hydrological results obtained in the Lange Bramke catchment are briefly outlined, while focusing on presenting an overview with respective references. It is shown that the operation of long-term hydrological research catchments, resulting in long-term high-quality measurements and data series, is fundamental for scientific progress in hydrology and for the characterisation of environmental changes.

AbstractThe Lange Bramke catchment has been investigated as a monitored catchment for 60 years. However, its utilization history even dates back to medieval times, and is well documented in part. The intense interplay between ore mining, forestry, and water resources exploitation left remains such as scoriae piles and modified forest growth, e.g. due to local pollution at smelter locations. It is demonstrated that considering local land use history is important for a proper understanding and interpretation of modern monitoring data. A theoretical framework is proposed for the integration of the two data sources. This requires a joint approach combining two modelling paradigms, the functional one dominating in current ecosystem research, and an interactive one which best characterizes the human–environment relationship in historic times.

Abstract The utilization history of the Lange Bramke catchment and the northern Harz mountains is dominated by ore mining. Historical documents were used to provide ample evidence that forestry and water utilization were managed according to administrative goals in a largely centralized manner. However, the perception of the landscape and its function and purpose have changed significantly over the centuries. In particular, the distinction between renewable (such as forests) and non-renewable resources (such as ore deposits) is a rather modern one, as is the principle of sustainability. This change in perception is apparent from the type of maps used, the different conflicts on property and exploitation rights, and the request for quantitative inventories of resources, appearing only quite late in the mining history. The remnants of smelters and charcoal production still demonstrate the importance of historical land use for proper interpretation of monitoring data.

Abstract High atmospheric inputs of nitrogen (N) during the last decades have caused an increase in NO3- leaching from forest soils in many European regions. In three research basins in the Upper Harz Mountains N output with stream water shows a clear increase until 1985 and a decline since then. The aim of this study was to evaluate a new spatio-temporal modelling approach (ForNic) and to assess the effects of forest management on N turnover in three small catchments in the Upper Harz Mountains with contrasting management activities in the past. Modelled time series of N output agreed satisfyingly with observed differences in N output between the three catchments. We conclude that the simple mass balance approach in combination with spatio-temporal parameterization of input parameters is useful to describe the dynamics of N retention and N output during forest development and the effects of forest management.

Abstract Investigations started 20 years ago in the Vallcebre research basins with the objective of better understanding the hydrological functioning of Mediterranean mountain basins. The Vallcebre basins are located in a Mediterranean mountain area of the Pyrenean ranges (northeastern Spain). Average annual precipitation is 862 ± 206 mm and potential evapotranspiration is 823 ± 26 mm. Climate is highly seasonal, leading to periods with water deficit in summer and, on occasion, in winter. Hydrological research in the basins is related to rainfall interception, evapotranspiration, soil moisture spatio-temporal dynamics, runoff response and runoff processes, suspended sediment dynamics and model application at both the plot and basin scales. Findings obtained over the last two decades have shown that, due to their intermediate position between drier and wetter climatic areas, the Vallcebre basins have a particular hydrological dynamic, which is specific to Mediterranean mountain areas.

Fundamental hydrological research results drawn from studies in small catchments

Abstract The history of research in small experimental and representative catchments in the 20th century is briefly described, in particular with regard to water quantity experiments. The early studies up to about the 1960s dealt with impacts of forest cover on runoff volumes and peak flow rates, but did not explain why catchments responded as they did. Stimulated by the IHD of UNESCO, from the 1960s numerous small research catchments have been set up for process studies to enhance the understanding of the hydrological behaviour of catchments. Although initially only precipitation and runoff could be measured, the technological developments in the 1970s opened the road for collecting time series of actual evaporation and soil moisture estimates. Many catchments studies have been conducted on runoff generation using, e.g. isotope information of the various flow components contributing to flood events. These and many other studies in small experimental and representative catchments have contributed much to a better understanding of the hydrological processes and to improved hydrological modelling.
