This book was written by the core team of geotechnical engineering at Tongji University. It is an upgraded and expanded version based on more than ten years of bilingual course materials for senior undergraduate and graduate students, and is suitable for international teaching in domestic universities as well as for reference by overseas geotechnical professionals. It aims to provide a systematic connection between the fundamental principles of groundwater and their applications in engineering practice, while introducing modern numerical and artificial-intelligence-based approaches for groundwater analysis and prediction. 

The manuscript is entirely written in standard academic English, with complete examples, engineering drawings and test data provided, and there are no copyrighted images.
