Abstract
<p>Sourcing subsurface evaporation (E<sub>ss</sub>) into groundwater (E<sub>g</sub>) and unsaturated zone (E<sub>u</sub>) components has received little scientific attention so far, despite its importance in water management and agriculture. We propose a novel sourcing framework, with its implementation in dedicated post-processing software called SOURCE (used along with the HYDRUS1D model), to study evaporation sourcing dynamics, define quantitatively “shallow” and “deep” water table conditions and test the applicability of water table fluctuation (WTF) and “bucket” methods for estimation of E<sub>g</sub> and E<sub>u</sub> separately. For the “shallow” and “dee...
