Maritime geotechnics is one of the most difficult specialties and is part of civil and coastal engineering. This book combines, defines and summarizes the role of the geotechnician in the coastal engineering, in terms of scientific research, design and construction. As this book cleverly collects between academic and professional side, so that ease to understand and solve the problems related to the conception, stability and construction of the maritime structure in an interdependent and complete manner. We have tried as much as possible in this book to give an academic and professional tool for geotechnicians so that he can get the knowledge and mastery of all the necessary measures and steps for the design and realization of maritime structures.
