PREFACE
Following the success of the first international conference on the planning,
design and operation of marinas, a second conference was convened to look
at further developments and trends within the marina field.
Again, the conference has attracted contributions from many different coun
tries, covering a multitude of topics from the feasibility stage to final con
struction and operation. Reference is made to a number of existing marinas
throughout the world which illustrate particular techniques and new ideas.
This volume contains edited papers related to the planning, design and op
eration of marina developments and has been subdivided into the following
sections:
Section 1: Overview of Yacht Marinas
Section 2: Planning and Feasibility
Section 3: Environmental and Water Quality Aspects
Section 4: Site Investigation and Water Level Control
Section 5: Wave Modelling and Analysis
Section 6: Flushing Characteristics and Water Circulation
Section 7: General Modelling of Marinas and Marine Structures
Section 8: Marina Developments
Section 9: Design and Construction
Section 10: Breakwaters
Section 11: Pontoon Services and Marina Maintenance
Section 12: Management and Marina Income
The conference was organised by the Wessex Institute of Technology and
held in Southampton from 31st March to the 2nd April, 1992.
The editor would like to thank the following:
• Dr C A Brebbia, Director of the Wessex Institute of Technology and
all staff of the Institute who helped make this conference a success.
• Jenny Mackenzie and staff at Computational Mechanics Publications.
• Members of the Organising Committee.
• The co-sponsors, namely:
The Institution of Civil Engineers, UK; The American Society of Civil
Engineers, USA; Hydraulics Research, UK; Permanent International
Association of Navigation Congress, UK; Yacht Harbours Association,
UK and Marina Management International, UK.
