It is expected that climate change will cause more frequent and more
intense precipitation events, which again will increase flood events. With more than half of the population in the world living in cities, the
problem of more frequent rain is a global problem that will require a
common and immediate effort to solve issues of stormwater and urban flooding.
Regarding managing stormwater, conventional pipe-based systems have been a crucial component of city infrastructure to transport stormwater and wastewater out of densely populated areas. The increased rain causes the overload of capacity on the conventional pipe-based drainage
systems. The expansion of these structures is not sustainable as the
system is not flexible during unexpected events of precipitation.
Arguably based on case studies an alternative solution that is more
adaptable to the change of climate is necessary. The concept of
Sustainable Drainage systems (SuDS) offers a more holistic and adaptable approach to urban flooding and stormwater management. SuDS Solutions vary from permeable surfaces, vegetation, green roofs, and rivers, and in this master, we focused on rivers as a SuDS strategy to mitigate against stormwater.
This master thesis deals with the complex issue of urban flooding in the city of Uyo in southern coastal Nigeria. The area is experiencing several
flooding events and their approach to managing the extensive water is to
expand and reconstruct the piped drainage system. We wish to explore the possibility of rivers as SuDS in Uyo and to manage to do that we are
Investigating how Oslo; Norway had a paradigm shift from a conventional
pipe-based system to integrate rivers as a strategy to manage urban flooding. To give Uyo a more sustainable solution we came up with this problem statement:
How can rivers/streams be used as Sustainable Drainage Systems (SuDS) to solve urban flooding in Uyo, Akwa Ibom, with lessons learned from the rivers in Oslo as a case study?
This thesis aims to find solutions for flood risk management in the city of Uyo, with a focus on the use of rivers as Sustainable Drainage
Systems. Further, the research explores the importance of local
participation and traditional knowledge in river management, as there is much to understand from these approaches to climate change adaptation.
The goal of the master thesis is to propose recommendations for sustainable river management that contribute to flood risk mitigation in Uyo, which can be used for other cities. We outlined steps to make this shift possible. The steps are mapping historical rivers, SuDS in urban planning, open stormwater projects, and involving the people, and the steps are outlined so it can be used in other places. | |
