Wetlands (i.e., marshes, bogs, and swamps) “are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water” .
There is hence a whole spectrum of diverse types of wetlands, and it explains why modelizing a wetland is such a challenge. But they are known to be key in protecting the biodiversity: they provide shelters for plants and species, where breeding, and feeding occur . Wetlands also have an immense value in flood protection and pollution control [4,6]. There is, consequently, a crucial need for understanding better the wetlands.
The project will consist of creating a numerical model of a wetland. It will be solved using standard FEA techniques and software (ansys/fluent, openfoam, etc.). In particular, it will allow to quantify the hydraulic performance of the wetland, and possibly to derive an ad hoc model. It will be fitted and compared to the available experimental data. Validation of the model will be carried out.
In addition to this, the porosity of the plants as a medium will be investigated. The influence of various parameters will be quantified, including for example the inclination of plants with respect to the time of the year, the variation in the water velocity due to different flow regimes, and the wind interference. It will be carried out using uncertainty quantification techniques, such as chaos expansion or Sobol analysis, or by fitting the model on the data, using Bayesian techniques.
In order to validate the model, on site experimental field work may be arranged to obtain new datasets if required. The work is of high interest and importance to the Environmentalists, Water Authorities & Councils, Regulators, Modellers, Wetland Designers, and other relevant stakeholders.
