Benchmarking test of empirical root water uptake models

Marcos Alex dos Santos, PhD student of the university of Brazil performed research at SLM in the period March 2013 – February 2014 where he performed numerous model simulations. Recently an interesting paper of the work which Marcos performed at SLM appeared in Hydrology and Earth System Sciences .


In many of our ecohydrological studies proper quantification of root water extraction plays an important role. Commonly relatively simple root water extraction concepts are used. Marcos compared a number of those simple concepts with an advanced root water extraction module. Also he derived input parameters for these simple concepts for various soil types, root densities and atmospheric demands. Finally he proposes a new, relatively simple root water extraction model, which compared best to the advanced root water extraction module.
