Changing Sea Levels: Effects of Tides, Weather and Climate

1 Review
Flooding of coastal communities is one of the major causes of environmental disasters world-wide. This textbook explains at a basic level, how sea levels are affected by astronomical tides, by weather effects that generate extreme flooding events, and over the longer term by ocean circulation and climate trends. It also indicates how sea level changes are related to changing risks, coastal dynamics, geology and biology; and outlines some of the economic and legal implications. Based on courses taught by the author in the UK and the USA, this book is aimed at undergraduate students at all levels, with the text developed in such a way that non-basic mathematics is confined to Appendices and a web site (http://publishing.cambridge.org/resources/0521532183/). Changing Sea Levels will also interest and inform professionals in many fields including hydrography, coastal engineering, geology, biology and also coastal planning and economics.

Only after reading a few pages, I have found this book very readable and also very interesting and would recommend it to anyone interested in their local, coastal environments. This is an area that will be very important to us all as we face sea level rises worldwide.

About the author (2004)

David Pugh was awarded a PhD in Geodesy and Geophysics from the University of Cambridge in 1968 before joining the Proudman Oceanographic Laboratory in Merseyside. In 1984 he became Head of Oceanography, Hydrology and Meteorology, Science Division, for the UK National Environment Research Council. He has also served as Secretary to the United Kingdom Government Committee on Marine Science and Technology and was elected President of the IOC (2003-2007), having previously been the Founding Chairman of the IOC Global Sea Level network, GLOSS. Dr Pugh maintains an active program of research associated with Liverpool University and the Proudman Oceanographic Laboratory. His interests include tides, surges, mean sea level, coastal management and climate change, the economics of marine activities related to GDP, and the history of sea level, and he is the author of two other books. He received an award from the Queen in 2003 for his services to marine sciences.
