Physical Simulation of Soil Hydrodynamic Processes is a theoretical and experimental textbook written for agricultural soil and water engineering, hydrology and water resources engineering, water conservancy engineering, geotechnical engineering, resources and environmental engineering and other related majors. The book has 30 chapters and 31 experiments in total. Among them, there are 6 experiments on the physical properties of soil water, 9 experiments on unsaturated soil water infiltration and evaporation, 11 experiments on saturated soil infiltration, 2 electrical simulation experiments on seepage and narrow slot experiments, and 3 additional testing experiments on surface hydrological process elements related to soil hydrodynamic processes. In addition, the measurement and control system for soil moisture content and sediment content and the superimposed spray simulated rainfall system are specifically introduced. This book takes experimental projects as the main line, comprehensively and completely introduces the theoretical system related to experiments, improves the derivation process of theoretical formulas, increases the discussion of relevant theories and concepts, and strives to be theoretically correct, conceptually accurate, and easy to understand. It provides independently developed instruments and equipment for physical simulation experiments of soil hydrodynamic processes and their design principles, and proposes experimental operation methods and data processing methods. Calculation examples for some experimental projects are given. This book can be used as a teaching material for undergraduates and graduate students in colleges and universities. It can also be used as an important reference for researchers when conducting research. It can also be used as a reference for teachers, students and related engineering and technical personnel in higher vocational universities, adult education colleges and secondary technical schools.
