Learning unit contents

The course aims to introduce the basics of modelling in the context of:

- subsurface hydrodynamics with an application to plant abstraction and solute transfer.

During this course, students will implement the various stages of the modelling methodology. This course also enables students to improve their understanding of transfer phenomena in porous media and the principles of modelling. The applications reflect concrete situations for bio-engineers, such as

- estimating the transfer of fertilisers or plant protection products to surface water or groundwater.

- heat exchange between soil layers

The course includes

- General modelling methodology

- Characterisation of soils with a view to modelling: continuous retention and conductivity functions, pedotransfer functions, thermal properties.

- 1D modelling of water, solute and heat transfers in variably saturated soils.

- Representation of transfers and transformations/degradations of solutes.

- Carrying out all the modelling phases to obtain validated descriptive and predictive models simulating changes in the populations of a species, the temperature of different soil layers or the carbon biomass of vegetation components.

Learning outcomes of the learning unit

 At the end of the course, the student will be able to:

- Set up a 1D hydrological model to represent a soil profile based on a pedological description.

- Carry out modelling under different conditions (presence of plants, irrigation, application of fertilisers, etc.).

- Formatting and discussing the results obtained (water and solutes).

- Understand the basic principles of digital diagrams to solve soil transfer problems.
