Course contents :
|
| This course aims at introducing basics of hydrodynamic modelling in soils with emphasis on plant uptake and solute transport and transformation.
This course allows 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.
The course includes
- soil caracterisation in the context of modelling : rentention and conductivity functions, pedotranfer functions
-notions of numerical calculation applied to hydrodynamic in soils
-modelling of solute tranfer and transformation/degradation.
- the study of computational tools allowing resolving 2D mass transfer problems in variably saturated soils. |
|
Learning outcomes of the course :
|
| After completing the course, the students will reach an intermediate level of competency in the following step of their cursus
- Establishing and validating a mathematical model
- identfying and quantifying the environmental threats to soil and water
- Identifying, testing and putting into practice environmental management measures
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 modellings 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 mass transfer problems in soils. |

Assessment methods and criteria :
|
| The students have to write a personnal report at the end of the period. If their evaluation is equal to or above 16/20, they do not have to attend the oral examination.
The students whom evaluation was below 16/20 have to pass the oral examination, composed of theory and exercice on computer.
The cotation system includes penalties in case of delay in the reports submissions. |

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. |
