This book embodies the principle of "equal emphasis on ports and waterways, and consideration of both rivers and seas" and systematically introduces hydrological knowledge with rich engineering practices. It aims to serve sea-related, navigation-related, and port-related projects, deeply analyzes engineering design concepts, engineering design parameter standards and definitions, and is committed to spreading the manufacturing technologies and design concepts of major waterway, coastal and ocean construction projects on global leading level. This book is written both for researchers and practitioners working in harbor, waterway and coastal engineering, hydraulic engineering, civil engineering, and ocean engineering.
