The manifold impacts of a rapidly changing environment are increasingly pressuring the sensitive water balance and require advanced monitoring approaches to develop sound water management practices. It has long been acknowledged that remote sensing observations can contribute to the knowledge of the spatial and temporal variations of hydrological quantities. Thus, a major focus of remote sensing research in hydrology and water resources management is to develop techniques for estimating hydro-meteorological states and fluxes. Specific examples include precipitation, plant physiology and growth, soil moisture, groundwater, snow, surface water or static basin characteristics such as topography or land use. Although major advances have been made on an experimental level, the use of remote sensing information in operational hydrology and water resources management has long been relatively limited. This is changing now as many remote sensing techniques, such as airborne laser scanning or spaceborne radar systems, are increasingly being used in an operational fashion. The application of remote sensing can be termed operational if at least one of two conditions are met: (a) the application produces an output on a regular basis, or (b) the remote sensing data are used regularly as part of a procedure to problem solving or decision making. However, additional research and development efforts are needed to better utilized the potential offered by remote sensing. This session therefore solicits contributions that either (i) demonstrate ongoing operational remote sensing applications in hydrology and water resources management or (ii) clearly show a strong potential of operationalisation in the near future. It is intended as a forum of information and discussion to contribute to a higher acceptance of remote sensing applications as a useful tool in water resources management and thus welcomes all hydrologists, hydrologic modellers and water resources managers and researchers to gather related information about up-to-date developments in remote sensing.
