Plants in water-controlled ecosystems: Active role in hydrologie processes and responce to water stress II. Probabilistic soil moisture dynamics


Journal Article

A stochastic model for soil moisture dynamics at a point is studied in detail. Rainfall is described as a marked Poisson process, producing a state-dependent infiltration into the soil. Losses due to leakage and evapotranspiration also depend on the existing level of soil moisture through a simplifying but realistic representation of plant physiological characteristics and soil properties. The analytic solution of the steady-state probability distributions is investigated to assess the role of climate, soil, and vegetation in soil moisture dynamics and water balance. © 2001 Elsevier Science Ltd.
