Physical models are valuable design tools in (landscape) architecture in many ways, but it is not the landscape architect’s habit to use this tool for dynamic landscape design. This thesis shows a way in which physical models can contribute to the explorative phases of (the) dynamic landscape design (process). It helps a designer to understand, think, test and communicate. On the one hand it is an effective, but on the other hand an explosive design tool. The design, design process and designer(s) depend whether or not to model and how; relating to abstraction and reduction, materials, techniques and scale/size. In this thesis a way is explored to use the physical model as a design tool for the explorative phases of dynamic landscape design, focussed on flowing water and growing vegetation for a specific phenomenological design process (and its design outcome). An iterative process is carried out in which an explorative search and in-depth study in literature and practice are supplemented with experiments and a case-study. Preliminary conclusions grow and develop till final conclusion. Although saturation was closely reached in the in-depth study, the results might have been influenced by the author’s preconceptions or expectations. The experiments carried out were not exhaustive and led by trial and error. The case-study offers one example for one design process. However, the whole process is extensively described and transcribed, which makes it a starting point for further research. Aim is to inspire designers to start modelling, to experience and apply this way of physical modelling, to develop knowledge, skills and experience. Sharing and applying the know-how this thesis creates, as well in study as in practice, hopefully leads to better design processes, ending up in better design solutions. Together we can identify, recognize and widen the habit of the landscape architect.
