Flood risk analysis in Oslo
Urbanization makes the urban surface impermeable and therefore reduce infiltration. This will increase the overland flood magnitude and reduce the response time. Together with urban development, climate change makes the problem of urban floods more challenging due to changes in the timing and magnitude of rainfall and snow melting events.
Flooding of urban areas poses great challenges to human safety and sustained economic growth. The Nedre Eiker municipality in Norway experienced approximately 170 mm of rainfall within a few hours on the 6th of August 2012 and the associated damage reach 317 mills. NOK. The expected damage cost due to urban flood can reach 45-100 billion NOK for the next 40 years if the Norwegian government and municipalities do not take actions.
This master thesis will study the overland flood risk in Oslo. The work includes overflood simulation using a two-dimension overland flow modeling and analysis of inundation considering topography and values of property.
The students will affiliate under two ongoing projects-New Water Ways (https://newwaterways.no/) and Sustainable Urbanization in the Context of Economic Transformation and Climate Change: Sustainable and Liveable Cities and Urban Areas. The student will contribute to these two projects and gain knowledge about stormwater management at both national and international levels.
