Description
The content of the module is organized into six sequences:
1) EU Introduction: scientific and operational issues of biogeochemical and water quality issues in agricultural watersheds;
2) Physicochemical and hydrological processes determining the availability and mobility of plant protection products in a watershed;
3) TD: modelling tutorials on the transfer of phytosanitary products;
4) Biogeochemical cycling of phosphorus in agro-systems ;
5) Nitrogen cycling and balance in agricultural watersheds;
6) TD : Evaluation of the nitrogen balance in a catchment area, diagnosis of the contamination of surface water
Objectives
The objective of this module is to present the biogeochemical functioning of watersheds by focusing on the analysis and modeling of processes determining the chemical quality of surface water, soil water and groundwater in relation to agricultural activities. To this end, the focus is on three chemical compounds with high environmental and sanitary stakes: phytosanitary products, compounds of the nitrogen and phosphorus cycles.
Necessary pre-requisites
