《波浪和海床交互作用的多孔介质原理(英文版)(精)》由郑东生所著，Porous Models for Wave-seabed Interactions discusses the phenomenon of wave-seabed interactions, which is a vital issue for coastal and geotechnical engineers involved in the design of foundations for marine structures such as pipelines, breakwaters, platforms, etc. The most important sections of this book will be the fully detailed theoretical models of wave-seabed inter-action problem, which are particularly useful for postgraduate students and junior researchers entering the discipline of marine geotechnics and off shore engineering. This book also converts the research outcomes of theo-retical studies to engineering applications that will provide front-line engi-neers with practical and effective tools in the assessment of seabed instabil-ity in engineering design.
