Current climate change trends are affecting the magnitude and recurrence of extreme weather events. In particular, several semi-arid regions around the planet are confronting more intense and prolonged lack of precipitation, slowly transforming these regions into deserts. In this thesis we present a stochastic (meso-scale) model for vegetation-precipitation interactions for semi-arid landscapes. Extensive simulations with the model suggest that persistence in current trends of precipitation decline in semi-arid landscapes may expedite desertification processes by up to several decades.

Water-soil-vegetation dynamic nexuses affect, and are affected by, both human activity and climate change. Inappropriate land management practices can result in soil and vegetation degradation, which in turn will likely alter natural hydrologic processes, leading to more frequent and severe flooding and drought. In response, an altered hydrologic condition tends to prompt soil erosion by wind and water, which can cause further vegetation degradation or even loss. Such nexuses will likely become more interwoven in changing climate because the non-stationary climate can further deteriorate the already-altered hydrologic condition. So far, our understanding is incomplete regarding how such nexuses maintain or break equilibriums between water, soil, and/or vegetation in terms of eco-environmental resilience. This book: 1) conceptualises the interrelated physical processes of water-soil-vegetation systems; 2) introduces mathematical models for simulating the processes; and 3) develops a variety of modelling cases of selected systems across the world.

Stochastic hydrology is an essential base of water resources systems analysis, due to the inherent randomness of the input, and consequently of the results. These results have to be incorporated in a decision-making process regarding the planning and management of water systems. It is through this application that stochastic hydrology finds its true meaning, otherwise it becomes merely an academic exercise. A set of well known specialists from both stochastic hydrology and water resources systems present a synthesis of the actual knowledge currently used in real-world planning and management. The book is intended for both practitioners and researchers who are willing to apply advanced approaches for incorporating hydrological randomness and uncertainty into the simulation and optimization of water resources systems. (abstract) Stochastic hydrology is a basic tool for water resources systems analysis, due to inherent randomness of the hydrologic cycle. This book contains actual techniques in use for water resources planning and management, incorporating randomness into the decision making process. Optimization and simulation, the classical systems-analysis technologies, are revisited under up-to-date statistical hydrology findings backed by real world applications.
