Evaporation, from the plot to the agricultural watershed

This course focuses on the observation and modeling of surface-atmosphere water and energy fluxes, integrated within watersheds or irrigated areas, to estimate and predict crop water requirements and water stress under drought conditions. Attention is given to the effect of spatial heterogeneities on fluxes, from the plot scale to the watershed scale. The effects of topography on surface fluxes are also covered. The course consists of two main parts:

1. Water and energy fluxes within the SPAC at the plot scale: a review of basic concepts in micro-meteorology, modeling surface-atmosphere fluxes for homogeneous crops (“big-leaf” approach), coupling with soil water transfers in the rooting zone, and water stress indicators at the plot scale
2. Water and energy fluxes within the SPAC at the watershed scale: spatial heterogeneity, the effect of advection on the fluxes, topographical effects on radiative and convective fluxes, and water stress indicators at the watershed scale.

The aim of this course is to provide the key concepts and modeling elements needed for an advanced understanding of green water and energy fluxes within the Soil-Plant-Atmosphere Continuum (SPAC), from the plot to the watershed scale.
