Assessment of evapotranspiration simulations in the Malše basin

Soil and Water Research, 2009
The application of the distributed hydrological model brings the benefits of assessment of the spatially distributed quantities which are hard to measure in the field over a larger area, e.g. evapotranspiration.

Graph‐based imitation and reinforcement learning for efficient Benders decomposition

AIChE Journal, EarlyView.
Abstract This work introduces an end‐to‐end graph‐based agent for accelerating the computational efficiency of Benders Decomposition. The agent's policy is parameterized by a graph neural network, which takes as input a bipartite graph representation of the master problem and proposes a candidate solution.

Determinants of the ratio of actual to potential evapotranspiration [PDF]

Global Change Biology, 2019
AbstractA widely used approach for estimating actual evapotranspiration (AET) in hydrological and earth system models is to constrain potential evapotranspiration (PET) with a single empirical stress factor (Ω = AET/PET). Ω represents the water availability and is fundamentally linked to canopy–atmosphere coupling.

Key soil health indicators under humid grazing lands

Grassland Research, EarlyView.
Soil health can be described using a few key soil health indicators that target a diversity of soil functions. This perspective article highlights how forage management affects these soil health indicators in humid‐zone grazing lands. Abstract Background Soil health describes critical soil functions influenced by land management. Although some key soil
