Sustainable decisions in water resources management require comprehensive and effectively integrated monitoring networks of water bodies and fluxes. This is exemplified by the Water Framework Directive, which establishes the requirements for the monitoring of surface water status, groundwater status and protected areas. New sensor technology, passive samplers and observational techniques can all work synergistically to monitor processes in a wide range of scales. However, despite the extreme spatial and temporal variability and the large range of scales of interacting processes, one cannot sample everywhere and all the time. Thus the challenge exists to use even rudimentary knowledge of the underlying variability, of cause-effect relationships, and of possible scaling relationships to optimize sampling network design and to integrate different monitoring networks.
This session therefore aims at presentation of innovative techniques i) to measure fluxes (evaporation, rainfall, runoff, solutes and pollutants) and their uncertainties (remote sensing, coupling with atmospheric models), ii) to monitor state variables (transformation and buffer capacities of soil horizons, storage variations in groundwater, soil moisture, surface water and snow pack) and their uncertainties (remote sensing, radar altimetry, gravity observations from space and on land, advanced TDR methods), and iii) to monitor the physical and physicochemical quality elements which will support the interpretation assessment and classification of a certain ecological status of water bodies.
Further focus is set on the development of Hydrological Observatories, which aims to facilitate development of integrated monitoring networks and hydrologic research by:
• Measuring hydrologic phenomena over broad spatial scales and long temporal periods;
• Creating a legacy of well-designed and documented long-term observations and experiments for use by present and future generations;
• Providing baseline data and short-term process studies for conducting major synthesis and theoretical efforts.
• Quantifying fluxes of elements and pollutants in order to come to a long-term forecast of trends in water and soil quality.
