Methodology

The hypothetical scenario focuses on flooding due to sea level rise in a high density area in Trondheim. The methodology used in the process of making this study spans across different means to gather, analyse and infer from primary and secondary sources of data. We studied about the conversations on sea level rise and its projected effect on high altitude cities like Trondheim. Parallely, a search for suitable sites began using different map sources and overlaying population density maps of the area with flooding risk due to sea level rise. Research suggested that certain areas of the coast of Nor- way could face up to 3m rise in sea level in the Trondheimsfjorden area (www.karteverket.no).

The area we decided on was Grilstad Marina because that’s an artificial island with around 1000 housings by the end of development. While the natural elevation in Trondheim protects most neighbourhoods and makes it possible to conduct rescue and relief operations with pre-planning, an artificial construction such as the Marina ought to take more precautions.

Kommune suggests that all new constructions must take into account a minimum of 3m rise in sea level by year 2100 (Trondheim Kommune, 2018).

A visit to the site was conducted to get a better understanding of the area. Visual mapping and photo documentation of the site allowed us to sketch over, analyse and ideate on the existing resilience measures on site. The site visit gave us a better understanding of how the buildings and the environment are connected. We observed that only one main road and two pedestrian bridges connect the island area to the mainland. This is a barrier for the safety of the area in the case of a storm surge or a rising sea level.

Further, structured and semi-structured interviews with the residents of the area gave us insight into the level of information that the community has about future risks. The general consensus among people is that the possibility of the area flooding is too low to be a concern given the area is quite high above sea level, and there is no record of previous flooding.
