Studenteropgave: Semesterprojekt


Recent research on climate changes express a need for new approaches to urban water ma-nagement as floods in bigger cities become more frequent in the future. This project exa-mines which climatic challenges the municipality of Copenhagen is facing and to what extent the city will be able to drain off precipitation using LAR (local draining of precipitation). The problem formulation is answered using theories based on urban hydrology and drainage basins. Furthermore this project is based upon data from interviews, reports from the municipality of Copenhagen and observations from the examined area. The analysis is based on a case study of the surroundings of Ryparken on Østerbro in Copenhagen and describes the different selected residential areas to determine what types of LAR solutions will be suiteable to implement. The project shows how the two biggest barriers in relation to implementing the LAR solutions are economy and environmental concerns for the groundwater balance. It is difficult to tell exactly how much water it is possible to retain using LAR, but it is possible to change the urban hydrology with these methods. It is concluded that one single LAR solution is not sufficient in order to prevent future floods. The project concludes that it can be recommended to use a combination of different types of LAR to delay precipitation run-off and moreover use an alternative solution, such as opening nearby steams, in addition to LAR.
