Finally, recommendations for future studies as well as alternative flood mitigation solutions were suggested to the municipality based on the data obtained from the results and their critical analysis performed during the study.

Uncertainties associated with model calibration, analysis technique and limitations of software were studied. Sensitivity tests were performed for the proposed solution i) by testing against a more extreme rainfall event and ii) by changing the size of the solution by 10 percent.
However, the blue-green solutions proposed in the Berghutskolan area were successful in protecting the area from flooding risk. Persamaan Pengatur Persamaan Kontinuitas p q.

Even though flood volume was significantly controlled in the Hulan area, there was still risk of flooding at the downstream point. Nita Yuanita Program Studi Teknik Kelautan Kamis, 10 September 2009. Similar results were obtained from both models, showing that blue-green measures are very effective in regulating stormwater runoff. While stationary disk cutting lathes engraved the signal in heavy wax disks, the R 21 used gelatine foil as its recording medium.

The effectiveness of the proposed measures was tested using two computer models - SCALGO Live and MIKE 21, and the results were compared. The R 21 was a portable disk recorder for electronic news gathering. Appropriate blue-green measures were proposed to regulate the stormwater runoff in both upstream and downstream areas. Using GIS analysis, high flooding risk was obtained for both study areas affecting mostly residential houses and residential streets. Further, this thesis work has also supported the municipality to develop and investigate climate change adaptation strategies to reduce or eliminate urban flooding risk for two study areas – Hulan and Berghultskolan. In the thesis work, this flood map was utilized to investigate infrastructure vulnerable to flood and to locate areas where risks to human life can arise. Lerum Municipality has realized this consequence of climate change and prepared a flood map for the municipality using a 2D hydrodynamic model to study the urban flooding risks and develop strategies to reduce these risks.
In Sweden, the annual precipitation amount is predicted to increase consistently towards the end of this century thus increasing the likelihood of urban flooding risk. A numerical model has been formatted including ocean, rain drainage, urban channels, and pumps by the software MIKE FLOOD which coupling MIKE URBAN, MIKE 11. Moreover, growing urbanization trend associated with population and wealth growth has caused increase in impervious surfaces, while lowering groundwater recharge. Vulnerability assessment of urban flooding in Lerum - Municipality and study of effectiveness of blue-green mitigation measures using software MIKE 21 and SCALGO LiveĪ much-realized consequence of climate change is shift in precipitation pattern and increase in extreme rainfall events.
