ABSTRACT:

How much terrestrial precipitation is used by vegetation and how much runs off, represents central issues in hydrologic science, ecology, climate change, and even geopolitics. We present a theory for the water balance to predict the fractional change in streamflow due to given fractional changes in temperature and precipitation. The theory involves a single parameter whose value is derived under the conditions of neither energy- nor water-limitations and, therefore, is not an adjustable parameter. By comparison with extensive data for precipitation elasticity εp at global scale, we find that the theory captures the key trends of the variations of the median value of εp with the aridity index AI . In contrast to a shortcoming of the classical Budyko phenomenology, namely, convergence to εp = 4 for large AI , our theory yields a value of 2 for the median value of εp for all AI > 1, in accord with the data for major river basins, as well as with the median value of summaries of global and continental data sets. Incorporating in the theory the effects of annual changes in water storage leads to the ability to predict the range of observed values of the elasticity as a function of the aridity index, or its inverse, the humidity index, as well as the run-off ratio. When changes in storage are neglected, the theory yields more accurate predictions for major river drainages than for small watersheds, particularly if the large basin spans various climate regimes and, as such, an integration over climates tends to reduce relative changes in the storage.

ABSTRACT:

Evapotranspiration, ET, is the most important climatic predictor of the net primary productivity, NPP, of ecosystems. It has also been shown that ET is the single climatic variable that best predicts plant species richness, n. We investigate whether a new theoretical expression for NPP in terms of climatic variables can be utilized to predict the variability of n across geographic regions. Our main hypothesis is that the most important input to the variability of n is climatic. We evaluate the proposed theoretical approach using a wide range of experimental data, collected from the literature. Our results appear to confirm the hypothesis underlying the research and are, therefore, compatible with the existing observations that n is strongly correlated with NPP.

ABSTRACT:

This Python code estimates the hydrogen relative permeability curve from the capillary pressure curve, mercury intrusion porosimetry curve, or pore-throat size distribution. The theoretical foundation is based on combining two upscaling techniques from statistical physics, i.e., percolation theory and effective-medium approximation. We apply the universal scaling law from percolation theory and the effective-medium approximation scaling to model hydrogen relative permeability at low and high hydrogen saturations, respectively.
