Ecohydrological modeling
Summary
This course provides the theoretical basis for understanding and modeling the interactions between the hydrologic cycle, vegetation, soil, climate, and human society.
Content
We will look at the dynamics of water, energy, carbon, and nutrient transport within the soil-plant-atmosphere continuum and we will introduce the tools necessary for their mathematical modelling. We will consider ecohydrological interactions from local to regional and global scales, as well as at daily to seasonal and annual time scales. The focus on multiple spatio-temporal scales will allow us to introduce a number of mathematical models, from analytical derivations to plot and catchment scale deterministic and stochastic approaches as well as global scale terrestrial biosphere models. We will conclude by presenting topical issues in ecohydrological research and applications, with particular focus on agricultural land use, climate regulation, food security, and environmental sustainability.
Course content:
- Introduction (soil-plant-atmosphere system, scales, ecohydrology and society)
- The soil (soil hydraulic properties, infiltration)
- The plant (water potentials, roots, xylem, leaves and stomata, transpiration, photosynthesis)
- The atmosphere (water/energy/carbon fluxes, atmospheric boundary layer dynamics)
- (Stochastic) soil moisture dynamics
- Soil carbon and nitrogen cycles
- Vegetation patterns
- Terrestrial biosphere modeling
- Model uncertainty
- Ecohydrology for forestry, agriculture, climate
- Food-water nexus, crop production and climate change
