HARTMAN, M. GRAHAM AND K. KIM Randle Reef at Hamilton Harbour, an Area of Concern (AOC), is the largest site in Canada contaminated with Polycyclic Aromatic Hydrocarbons (PAHs). A collaboration of municipal and federal entities is working on remediation measures. PROVEN BENEFITS OF POLYMER USE IN THE TREATMENT 10 OF SEDIMENTS IN DREDGING PROJECTS A. BOISSON AND F. COUTURIER To show the success of polymer use in highly contaminated areas, two recent projects are presented: at Port-La-Forêt harbour in La Forêt-Fouesnant, France and at the Kishon River seven kilometres downstream from Haifa, Israel. AN IMPROVED INTEGRATED APPROACH FOR OPTIMISING 17 SHIPPING CHANNEL CAPACITY FOR AUSTRALIAN PORTS S. MORTENSEN, B. JENSEN, A. HARKIN, M. TREE, T. WOMERSLEY AND R. NAVE The continuing surge in vessel sizes is putting increased pressure on port authorities worldwide. Experts recount the implementation of innovative modelling for maintaining channel depths at the ports of Brisbane and Geelong, Australia. 13 NOMINATIONS IN THE RUNNING FOR IADC'S SAFETY AWARD 2017 25 Van der Meer Safety is the number one priority during dredging operations and IADC’s Safety Award Modern design of berm breakwaters began about thirty years ago. However, to date, there Sigurdarson Advanced Series on Ocean Engineering — Volume ?? has been a lack of a well-established, formal design methodology on berm breakwaters. The authors Dr Jentsje van der Meer and Sigurdur Sigurdarson combine over 40 years of aims to promote awareness through innovation. Thirteen nominations are in the running collective experience working with breakwaters to put forwarded a design framework in Design and Construction of Berm Breakwaters; covering the science and design practices of berm breakwater structures. The original design consisted of mass armoured berms to receive the 2017 Award. that reshaped into statically stable S-shaped slopes. The design was adopted in Iceland DESIGN AND and eventually led to a development with more stable structures by using available rock sizes, large rock, and more rock gradings than just “small rock (core)” and “large rock DESIGN AND CONSTRUCTION (berm)”. This more stable and only partly reshaping structure is called the Icelandic-type CONSTRUCTION OF berm breakwater. OF BERM BREAKWATERS Written for researchers and practitioners, the volume consists of chapters on geometrical designs of the berm breakwater cross-section, including berm reshaping and wave BERM BREAKWATERS overtopping, quarry and project management, as well as blasting and sorting techniques, designs for various wave conditions and available rock classes, and case studies of already constructed berm breakwaters. About the Authors BOOKS/PERIODICALS REVIEWED 32 Dr Jentsje van der Meer is a well-known expert in appraisal, design, and testing of breakwaters and coastal structures; including levees, dikes, embankments, seawalls, breakwaters, groynes, revetments, shingle beaches and river dikes. His work on rubble mound structures has been included in all manuals all over the world. He has worked at Delft Hydraulics, now Deltares, a well-known institute on specialised consulting and research of Design and Construction of Berm Breakwaters fuses scientific knowledge water related issues, for 16 years. For ten years he had a position at Infram International, a private consultant for infrastructure appraisal and management, where he exploited his accrued during 30 projects around the world, while a new report from PIANC experience in specialized consultancy and research. In 2007 he started his own company, Van der Meer Consulting BV, on Coastal Engineering Consultancy & Research. In 2014, he became a part time professor of Coastal Structures and Ports at UNESCO-IHE, Delft, The facilitates the selection of breakwater types and safety features by designers. Netherlands, with also a 0-fte position at Delft University of Technology. Sigurdur Sigurdarson has over 30 years of experience as a coastal and harbour engineer, both in Iceland, as well as internationally, working on breakwater projects in four continents. His main emphasis has been on coastal structures, including breakwaters, revetments and groynes. He has been involved in all aspects from planning of structures, establishment of environmental load and design criteria, design, model testing and armourstone quarry evaluation, through to tendering, construction management, supervision of construction and quarrying, as well as performance monitoring. Through a number of breakwater Jentsje van der Meer Meer projects, he has developed and introduced the Icelandic-type berm breakwater. Sigurdarson Sigurdarson established the IceBreak Consulting Engineers, which specialises in breakwaters and armourstone quarrying, in 2010.
