Norwegian Experience in Sustainable Water Management, Environment Protection, Flood and Erosion Control and Climate Development Research
This paper aims to provide an overview of experience for sustainable water management in Norway. It covers professional areas of integrated water management including urban stormwater management, hydropower development and environment protection, hydrological data collection and flood control, soil erosion and control measures from agricultural areas, ecosystem conservation in river catchments and sediment transportation, and the long-term development of climate change. Water management should be systematic and predictable, and based on the principle of legality. Selected central acts regulating water management aspects, important regulations including regulations on drinking water, sewage purification, licence fees, safety and supervision of watercourse installations were reviewed. The recognition of the economic value of water is visible in many parts of Norwegian water legislation. Several aspects of urban stormwater management, as a whole of integrated water management, were highlighted in part 1 of the paper. Hydropower development related regulations concerning on environment protection were described in part 2. Floods caused by typical climate in Norway, structural and non-structural measures to mitigate floods were summarised in part 3. Erosion from agricultural areas, control measure, monitoring system were summarised in part 4. Research regarding erosion process in river catchments, glacial erosion, and erosion in clay areas, mountain and arctic rivers, and sediment transportation in rivers were presented in part 5. Climate development in Norway during 1900～2100 was given in the last part of the paper, where regional climate downscale models, empirical and dynamical downscaling, were introduced. Results of climate variation-temperature and precipitation in Norway in the latest 100～150 years and scenarios of climate development during the 21st century were presented.
