  • Research
    EU prescribes that water management strategies must be developed at catchment scale instead of according to administrative bounds So far the vast majority of the hydrological process understanding has been obtained at small scales 10 km2 and thus there is a disparity between the scale at which the current process understanding is based and the scale at which future hydrological consequences need to be addressed Recent studies have shown that basic climatic and hydrological fluxes are inaccurately determined at catchment scale which has led to problems with closure of the water balance In a recent national water resources assessment it was necessary to introduce empirical correction factors to simulated net precipitation to obtain a closure of the water balance at catchment scales Despite using state of the art hydrological modeling techniques the estimate of the groundwater resources is uncertain Moreover research focused on water quality problems have to a large extent been focused on contamination by point sources Thus the investigations have been done at small scales and as a result the findings have not been derived for large scales Furthermore global climate change research networks which monitor analyze and forecast the impact on ecosystems do not address the scaling

  • Objectives
    sensing sensors to establish a unique multi scale dataset The data provide the basis for improvement of the integrated understanding of hydrological processes at catchment scale and the development of integrated and physically based hydrological models The data constitute an invaluable platform for long term innovative interdisciplinary hydrological research at the highest international level The collected project data are routinely imported in a user friendly database It consists of historical meteorological hydrological and geological data from the catchment The database facilitates easy data sharing among the scientists and students affiliated to HOBE and dissemination of data to interested parties according to a data policy The center activities have resulted in new knowledge and understanding of the individual hydrological processes such as precipitation soil moisture patterns evapotranspiration emission of greenhouse gasses and groundwater fluxes to streams and Ringkøbing Fjord Furthermore innovative results have been obtained with respect to integrated hydrological modeling of the entire catchment in relation to closure of the water balance and parameterization of distributed hydrological models The research results have improved the scientific basis for better water resources management and for reducing the uncertainty in water balance closure at catchment scale The latter is currently a pertinent problem for accurate assessment of the water resources in Denmark The research accomplishments obtained in HOBE have been published in international journals A very important contribution is a special issue of the Vadose Zone Journal vol 10 2011 The issue is a significant showcase to the international research community HOBE has gained considerable international attention which among others is reflected by the invitations to present the center s research at conferences in Europe and USA and by the international researchers visiting the center HOBE has also created widespread interest at the national level The center is now the pivotal point for
