Abstract:Due to changing climate change predictions resulting in more intense rain in combination with larger urban areas, municipalities, water boards and provinces are not only focusing on their sewage systems but also on flood measures in spatial planning to prevent urban flooding. This has resulted in a flood resilient urban spatial planning sector, which cares about minimizing the consequences of floods, but at the same time allowing some flooding. By allowing some flooding, smaller changes are needed to minimize flooding in the, often space-limited, urban environment. In order to support the decision making process in flood resilient urban spatial planning, computer simulation models are available which could assess the effectiveness of spatial measures. These models could be used in an interactive manner which makes it possible to pause a flood calculation in order to make adjustments (for example raising or lowering a specific piece of land). This gives users direct feedback during a calculation, e.g. when used during meetings. An example of such a model is 3Di. However, in current work processes such interactive models are hard to implement. Therefore the goal of this research is to find out what aspects of current decision making process could be changed in order to evaluate how this process could be shaped to be more suitable for the use of an interactive water management model. A first step towards this research goal was to identify the current decision making process in flood resilient urban spatial planning. After a literature study a questionnaire is developed and distributed among a broad field of stakeholders in flood resilient urban spatial planning. The results of the questionnaires are used to define which aspects of the decision making process could be changed. The second step was to investigate the possibilities of implementation of 3Di in flood resilient urban spatial planning. Workshops in which 3Di is used at municipalities, water boards and related organizations are visited and interviews are conducted. Also model purposes are reviewed. A case study of the formation process of a Basis Sewage Plan (Dutch; ‘Basisrioleringsplan’ [BRP]) is conducted. The results of the case study are, together with the results of step one and two used to evaluate how a decision making process could be shaped to implement 3Di.
