Theme C

Focus Area Hamburg-Lohbrügge

Field Work and Quantitative Modelling in C1 focus area Hamburg-Lohbrügge

To promote joint interdisciplinary work, a focus area was defined in the project: Hamburg-Lohbrügge. The focus area was chosen to be representative of other urban areas in Hamburg and worldwide. A key selection criterion was that the focus area combines different focal points in terms of urban morphology, social and economic structures and future development. Of particular interest is a well-detected heavy rainfall event in Hamburg-Lohbrügge that occurred on May 10th, 2018, which will be used to evaluate the precipitation-runoff modelling chain. In order to get to know the perspectives of the different disciplines, we conducted a joint walk-through of the Lohbrügge focus area in October 2020. 

Field work in Hamburg-Lohbrügge:

In Lohbrügge, a series of three workshops will take place between December 2023 and May 2024 with additional go-along interviews in the focus area. The go-along interviews have the intention to highlight the narratives of each interviewee based on their very own water perception / water story within Lohbrügge and their every-day water habits. The first workshop invites all interviewees from the go-along interviews to do a collective mapping of water-related areas within the focus area by using their very own symbols, that are commonly created in the workshop. The second workshop invites stakeholders which are working on water-related topics in Lohbrügge to do the same process, a collective mapping action. The third workshop will combine both stakeholders and the interviewees and thus compare and discuss the results from both workshops. In general, the aim is to create a common water picture for the focus area of Hamburg-Lohbrügge with residents and stakeholders to identify water-related hotspots of risk, adaptation, urban planning, well-being, community use and other water-related issues important to the participants.

Quantitative Modelling in Hamburg-Lohbrügge:

The heavy rainfall event over Hamburg-Lohbrügge in 2018 is used for evaluating the developed precipitation-runoff modeling chain. In addition, the possible adaptation scenarios for Hamburg 2050 developed as part of the C1 project will be applied to the Hamburg-Lohbrügge model domain and the effects of adaptation will be assessed using the precipitation-runoff modeling chain for physically plausible future heavy rainfall events.
