The climate is inevitably changing and in Denmark, the intensity of rainstorms have increased as have the frequency. Our first response to solve our stormwater challenges have been to build larger drainage structures and to manage water utilizing a multitude of structures to handle stormwater outside the usual sewer and drainage systems. In most Danish cities it has turned out that building retention space can be less costly compared to building drains and sewers. Inexpensive retention space can be found on parking lots, in roads and in the urban greenery and we have moved towards a system with thousands of small retention volumes distributed in the city. In order to maximize the value of the retention volumes it is necessary to build a new digital infrastructure to manage and operate these. This has forced the utilities to build a dense monitoring network and to share data across administrative boundaries. The presentation will tell the story about the need for digitalization in the Danish water industry and give examples new digital solutions.
Presentations present Ole Larsen working at the Climate Adaptation Living Lab in Copenhagen.
Ole Larsen graduated from the Technical University awarded a PhD in reactive transport modelling in 1998. He worked as a Post Doc scientist at the Max Planck Institute in Bremen working with exchange rates over marine benthic interfaces using advanced sensors and radiotracers. In 2001 he founded the office of DHI in Germany and after the devastating floods in 2002 worked predominantly with water resource management and flooding. He has developed novel sensors and monitoring systems and used high resolution radar to monitor rainfall for urban forecast systems and developed extreme value based methods for impact assessments used in the insurance industry based on TRMM and GPM rainfall data. A large share of Ole Larsen’s activities are directed towards risk management utilizing stochastic risk modelling methods. Since 2017, Ole Larsen has directed the Climate Adaptation Living Lab in Copenhagen (CALL Copenhagen) established by the capital region of Copenhagen and the main utility companies. The prime objective of CALL is to promote and accelerate climate adaptation following the severe rainstorm in 2011 (135 mm rainfall) causing unprecedented losses in Denmark.
Ole Larsen is the author of over 40 scientific publications, specialist in rainfall measurements, hydrological and hydraulic modelling. He act as expert advisor for IFC, World Bank, Insurance Industry, Cities and Utilities.
