Because of the design of the treatment wetland (98 m long, a single feed point opposite the outlet point, a drainage network limiting the uniform distribution of water flows), the mechanistic model results in a calculation code representative of the complexity of the system but costly in terms of calculation time. As the aim of the Life ADSORB project is to simulate the behavior of the filter over the long term, it is not possible to use the mechanistic model alone. It was therefore decided to use a surrogate model: spatial exploration of the mechanistic model variables (input conditions, initial conditions and hypermarameters) and then fitting a regression model to the model outputs. The surrogate model thus established can be used to assess the filter's behavior over the long term.
