Features: This book is a summary of the author's long-term research on farmland drainage. It provides an in-depth and systematic discussion of various complex issues in farmland drainage and offers comprehensive theoretical analysis. Starting from the fundamental equation of unsteady seepage flow in farmland groundwater drainage, it integrates various boundary conditions, initial conditions, and natural factors such as evaporation, precipitation infiltration, and upward replenishment from deep confined water, conducting a comprehensive analysis and research. A series of achievements have been obtained, making this a specialized monograph on groundwater drainage. The book is suitable for farmland irrigation and drainage engineering planning and design personnel, as well as those engaged in drainage and improvement of saline-alkali land. It can also serve as a reference for professionals and researchers in fields such as farmland irrigation and drainage, hydrogeology, groundwater resources, and soil improvement, as well as educators and researchers.
