This book treats the subject of porous flow and its applications in three engi-
neering and scientific problems. The first major part of the book is devoted to

solute transport in unsaturated porous media. Dynamic hydraulic conductivity
and degree of saturation associate with pore pressures are also included in the

consolidation-induced solute transport process. The second part of this book fo-
cuses on tidal dynamics in coastal aquifers, including shallow water expansion for

sloping beaches, two-dimensional problem in estuarine zone and leaky confined

aquifers. The final part of the book summarizes the recent development of po-
rous model in the field of liquefaction around marine infrastructures including

fundamental mechanisms of momentary and residual seabed liquefaction, two-
dimensional and three-dimensional porous models for fluid-seabed interactions

around breakwaters, pipelines and piled foundations in marine environments.
The authors’ aim is to describe in detail the applications of porous models for
several engineering problems. This book will provide academic researchers and
industry an overview of recent development in the field of porous models and
the applications.
