The Norwegian Water Resources and Energy Directorate (NVE) is responsible for the administration of Norway's water and energy resources. Data characterizing the quantitative aspect of the land phase of the hydrologic cycle are gathered daily. Currently the national groundwater and soil water observation network comprises 16 automatic gauging stations for soil moisture and 66 stations for groundwater. But this sparse network does not cover the whole country properly. It is therefore necessary to establish hydrological models to monitor the groundwater resources on both local and national scales. Such models are prerequisite to forecasting future conditions, especially in emergencies.
A new project which aims at developing tools for providing the authority and the general public with daily information on groundwater and soil water conditions has been initiated. A spatially-distributed conceptual precipitation-runoff model (HBV model) is adopted. It carries out water balance calculation in each grid cell element on a daily basis. Real-time observations are applied in addition. A Web- and GIS-based framework originally intended for generating snow, water and climate maps is now further developed and used to disseminate these findings (seNorge.no). A few examples from the period of 1990-2007 will be given to illustrate the applicability and potential of the system.
