Learning unit contents
This course aims at introducing basics of
- hydrodynamic modelling in soils with emphasis on plant uptake and solute transport and transformation.
- modelling the population dynamics and the matter and energy transfer in the terrestrial ecosystems
During this course, the students will implement the different stages of the modeling methodology. This course allows also the student to improve their understanding of such phenomenon and the principles of modelling. The exercices are based on situations related to the professionnal context of bioengineers, i.e. quantification of water flows to surface and groundwater and the related transfer of nutrients and pesticides; heat transfers in the soil layers; exchanges of carbon in the crops and temporal evolution of the number of members from one population.
The course includes:
- The general methodology of modelling
- Soil caracterisation in the context of modelling : rentention and conductivity functions, pedotranfer functions, thermal properties.
- Notions of numerical computation applied to hydrodynamic in soils.
- 1D modelling of water, solutes and heat transfers in variably saturated soils.
- Representation of tranfers and transformation/degradation of solutes.
- The study of computational tools allowing resolving 1D transfer problems in variably saturated soils.
- The study on the main model types for population dynamics (Malthus, Volterra) and for the energy and biochemical cycles in ecosystems
- The achievement of all the model building phases to obtain some validated descriptive and predictive models
Learning outcomes of the learning unit
By the end of the course, the student will have reached an intermediate level of skills in the different step of development:
- Design and model scientific and technical solutions, support decision.
- Optimise and manage fluxes between water, soil, fauna, flora and atmosphere.
- Design and implement solutions of environmental remediation in soil-water-plant systems and atmosphere.
- Design and manage environmental and geographical database systems and develop tools for interpretation, cartography, spatial modelling and diagnostic.
In addition, the course certifies that the students are able to "compare and discuss the choice of appropriate models in order to establish predictions, interprete results and conclude a research work".
More particularly, the students will be able to:
- Parametrize a 1D hydrodynamic model in order to represent a soil profile on the basis of a pedologic description.
- Perform simulations in various conditions (with plants, under irrigation, fertilizers application, ...).
- Present its results and discuss them (water and solutes).
- Understand the basic principles of computational frameworks to resolve transfer problems in soils.

Planned learning activities and teaching methods
oral lectures and computer workshops
Mode of delivery (face-to-face ; distance-learning)
25% lectures
75% workshops
Recommended or required readings
"soil physics with hydrus" Radcliffe and Simunek 2010 slideshows and articles (available on eCampus)
Assessment methods and criteria
The evaluation is based on a personnal work, written report (some parts of it might be done by groups), numerical apllication and oral discussion with teachers.
The three domains covered by the course have to be mastered by the students. A lack of knowledge in one of those will be reflected in the final mark.
Work placement(s)
Organizational remarks
It's compulsory for students to attend the workshops. In case of unjustified absence, a penalty will be applied on the final cotation.
