Overview on the applications of random wave concept in Coastal Engineering
Proceedings of the Japan Academy. Series B Physical and biological sciences, 2008Co-Authors: Yoshimi GodaAbstract:When “Coastal Engineering” was recognized as a new discipline in 1950, the significant wave concept was the basic tool in dealing with wave actions on beach and structures. Description of sea waves as the random process with spectral and statistical analysis was gradually introduced in various Engineering problems in Coastal Engineering through the 1970s and 1980s. Nowadays the random wave concept plays the central role in Engineering manuals for maritime structure designs. The present paper overviews the historical development of random wave concept and its applications in Coastal Engineering.

AN OVERVIEW OF Coastal Engineering WITH EMPHASIS ON RANDOM WAVE APPROACH
Coastal Engineering Journal, 1998Co-Authors: Yoshimi GodaAbstract:A historical review is made on the development of Coastal Engineering from the empirical stage of harbor Engineering in the old days to the present stage of sophistication. Emphasis is placed on the incorporation of random wave concept into Coastal Engineering, and its importance in Engineering practice is discussed. Progress with regard to random wave approach in Japan is described in some detail. Present and future topics related with random wave approach are also presented.

UAV applications to Coastal Engineering
Australian Coasts and Ports 2015 Conference, 2015Co-Authors: C.d. Drummond, Ian L Turner, A.n.a. Matheen, Mitchell D. Harley, William C. GlamoreAbstract:The use of UAVs (Unmanned Aerial Vehicles) as a mapping and measurement tool has grown significantly in recent years, such that the potential for Coastal Engineering applications is beginning to be realised. Whereas more-traditional land-based (e.g. RTK-GPS) or airborne (e.g. LiDAR) methods of collecting topographic data over large areas can be labour-intensive and/or costly and physically restrictive, UAV surveying now has the ability to provide a cost-effective solution for rapid airborne sampling of the Coastal zone at high-accuracy and very high spatial resolution. This paper presents an overview of the use of UAVs for Coastal Engineering applications, starting with the different types of systems available, practical considerations such as UAV regulations and flight planning considerations, photogrammetric data postprocessing techniques (the Structure-from-Motion algorithm) and examples of resulting data products. A number of Coastal Engineering case studies that have been conducted recently by the authors using UAV technology are then presented. These applications include rapid pre- and post-storm UAV deployment for quantifying Coastal impacts of a major storm event that struck Sydney in April 2015; an evaluation of a rubble-mound breakwater on the mid NSW coast for structural damage and armour volume analyses; and vegetation mapping at a Coastal estuary entrance using a near infra-red sensor. The Coastal Engineering applications presented highlight the enormous potential of UAV technology to significantly improve and potentially revolutionise the future of Coastal zone monitoring.

Coastal Engineering quo vadis
Coastal Engineering, 2006Co-Authors: J. W. KamphuisAbstract:Abstract This paper traces the development of Coastal Engineering, drawing parallels with history of civilization and development of society in general. It recognizes three distinct ages—those of providence, progress and nihilism. It recalls the impact of the enlightenment and describes the rise of the modern era, in which Coastal Engineering has its roots; the time with the underlying motto “yes we can!” Next, we follow the move to postmodernism where we find that our models have practical limits, that there are no single, correct answers and that good Coastal Engineering is not necessarily good. We explore the concepts of uncertainty, pluralism and sustainability. Finally, we attempt to find some direction to proceed with Coastal education, research and management within the postmodern environment.

physical models and laboratory techniques in Coastal Engineering
1993Co-Authors: Steven A HughesAbstract:Laboratory physical models are a valuable tool for Coastal engineers. Physical models help us to understand the complex hydrodynamic processes occurring in the nearshore zone and they provide reliable and economic Engineering design solutions.This book is about the art and science of physical modeling as applied in Coastal Engineering. The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to Coastal Engineering models.Practical application of similitude principles to Coastal Engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).
