abstract = {In this study, entropy production optimization and
inference principles are applied to a synthetic semi-arid
hillslope in high-resolution, physics-based simulations. The
results suggest that entropy or power is indeed maximized,
because of the strong nonlinearity of variably saturated
flow and competing processes related to soil moisture
fluxes, the depletion of gradients, and the movement of a
free water table. Thus, it appears that the maximum entropy
production (MEP) principle may indeed be applicable to
hydrologic systems. In the application to hydrologic system,
the free water table constitutes an important degree of
freedom in the optimization of entropy production and may
also relate the theory to actual observations. In an ensuing
analysis, an attempt is made to transfer the complex,
"microscopic" hillslope model into a macroscopic model of
reduced complexity using the MEP principle as an
interference tool to obtain effective conductance
coefficients and forces/gradients. The results demonstrate a
new approach for the application of MEP to hydrologic
systems and may form the basis for fruitful discussions and
research in future.},
