GSS2022 - June 16 - GEOSPACE 1D and Heat transport in GEOframe

Previous day material - Next day material - Index

This day of the GEOframe Summer School is dedicated to presenting the GEOSPACE model, the Soil Plant Atmosphere Continuum Estimator model of GEOframe, both the theory and the practical session. It is also dedicated to the derivation of Advection-Dispersion/Diffusion equation and its application to the heat transport in soils.

EVAPOTRANSPIRATION

A consistent part of root zone and surface water evaporates and returns to the atmosphere to eventually form clouds and precipitation again. The process follows quite complicate routes and is different when happening from liquid surfaces, soil or vegetation (and BTW animals).  In this group of lectures we try to figure out the physical mechanisms that act in the process and give some hint on methods to estimate evaporation and transpiration with physically based models.
