We introduce Wetropolis: a mathematical and physical model set-up. Wetropolis consists of a random weather or rain machine driving rainfall in a down-scaled river-catchment landscape. When this randomly determined rainfall is extreme, we will observe flooding in a conceptual city. Wetropolis visualises the random nature of a return-period or Annual Exceedance Probability (AEP) for extreme events. Instead of waiting for on average 100 years for a 1:100yr flood, Wetropolis’ return-periods for 1-2-3-day(s) of extreme events are shorter, circa 50s, 5min and 28min on average, while a “Wetropolis Day” is only 10s.
Interactions with flood professionals revealed that Wetropolis should be used as a policy and scientific flood investigator. Hence, we arrive at the following main objective: we will employ Wetropolis to investigate modern (machine-learning) forecasting tools, flood control, and validate model forecasts against Wetropolis as a scientific laboratory experiment.
