2019b). In figure 16 we predict the effect of them on Bakklandet`s Nidelva river facade. The red lines represent expected major flood events, the blue ones, average expected sea-level rise with the current, highest level of the river.

In the final, long term of our plan, due to a wealthy and involved government as well as residents of the area, we chose to create the worst-case scenario as the one planned for, which with substantial resources we have an opportunity to tackle. As the worst-case scenario, we understand the predictions for the year 2100 sea level rise and floods. Firstly, the average sea level rise for the year 2100 is predicted to be affecting some of the land on Bakklandet. Based on the map presented in figure 12, we estimate a sea level rise of 2 meters in 2100, as the safe capacity, in that time frame. As visible on figure 12, only a small part of Bakklandet would be covered of Nidelva in that scenario, yet that land happens to be covered with constructions of a bridge and houses lifted on poles above the land level. Apart from lifted buildings, few openings in the river`s buildings` facade are endangered according to the map. Although, through looking at the urban facade of the river and piers we point out the main dangers of sea level rise. First, the foundation and poles, as well as the soil and the river bottom that the buildings connected to the river are built on, have to be checked for sustaining longer periods of river Page 27 of 36
