Waves in Ocean Engineering
by M.J. Tucker and E.G. Pitt
Publisher: Elsevier; ISBN: 0-08-043566-1; Price: 134 Euro; 2001
This book covers the whole field of wave studies of interest to applied oceanographers and ocean engineers. It has considerable relevance to coastal engineering. The book is split into 12 sections, the first of which is devoted to the practical applications of wave studies and to the history of wave research. The rest of the book covers the measurement of waves, including remote sensing; the analysis and interpretation of wave data; estimating the properties of the extreme "Design Wave", as well as of the generality of waves for fatigue calculations; waves in finite depth, wave generation by wind and wave forecasting models; non-linear effects, and errors and uncertainties in wave data.

Pipelines and Risers
by Y. Bai
Publisher: Elsevier; ISBN: 0-08-043712-5; Price: 134 Euro; 2001
This book summarizes the author's 18 years of research and engineering experience at universities, classification societies and design offices. The intention is to develop this book as a textbook for graduate students, as it includes design guidelines for engineers and references for researchers. It is hoped that this book may also be used to aid the design of offshore structures as it details applied mechanics and design/engineering.

Theory and Applications of Nonviscous Fluid Flows
by R.K. Zeytounian
Publisher: Springer; ISBN: 3-540-41412 6; Price: 74.95 Euro
The purpose of this book is to present a broad panorama of model problems encountered in nonviscous Newtonian fluid flows. This is achieved by investigating the significant features of the solutions of the corresponding equations using the method of asymptotic analysis.

COAST3D project results on-line
The Scientific Results of this important European Research project on Coastal Morphodynamics have been published on-line. The EU funded COAST3D project (1997-2001) has the objective of:
-to improve understanding of the physics of coastal sand transport and morphodynamics
-to remedy the present lack of validation data of sand transport and morphology suitable for testing numerical models of coastal processes
-to test a representative sample of numerical models for predicting coastal sand transport and morphodynamics against this data
-to deliver validated modelling tools, and methodologies for their use, in a form suitable for coastal zone management
-to deliver a set of guidelines for practical coastal zone management (CZM)
The project COAST3D has recently finished, and the scientific results are available on the project website:

UNEP.Net Freshwater Portal
The declining state of the world's freshwater resources, in terms of quantity and quality, may prove to be the dominant issue on the environment and development agenda of the coming century. If present consumption patterns continue, two out of every three persons on Earth will live in water-stressed conditions by the year 2025. In order to help environmental assessment professionals and policy makers keep up to date with the most authoritative information on this critical environmental field, the United Nations Environment Programme (UNEP) opened the UNEP.Net Freshwater Portal, an online gateway to information about freshwater.

Floods, droughts, poverty and science
by W.J.R. Alexander, Professor Emeritus, Department of Civil Engineering, University of Pretoria.
"Poverty is tearing Africa apart. It is the root cause of internal unrest, cross-border conflicts, land redistribution problems and political instability in many African countries. Natural disasters (principally floods and droughts) are often the triggering mechanism for the downward spiral of impoverishment and eventually to anarchy if not brought under control. Is there anything that scientists can do to check and reverse this trend?"

2003: International Year of Freshwater
The United Nations General Assembly has proclaimed the year 2003 as the International Year of Freshwater. The resolution, adopted on 20 December 2000, was initiated by the Government of Tajikistan and supported by 148 other countries. It encourages Governments, the United Nations system and all other actors to take advantage of the Year to increase awareness of the importance of sustainable freshwater use, management and protection. For more information contact Mr Manuel Dengo or Ms Marcia Brewster at dengo@un.org and brewster@un.org respectively.

Postgraduate Masters Course on Hydroinformatics
Hydroinformatics uses simulation modelling and information and communication technologies (ICT) to help us understand and solve problems of hydraulics, hydrology and environmental engineering for better management of water-based systems. Increasingly, new ICT tools are being introduced to collect and analyse hydrological, hydrometric and water quality data. In 1991 IHE was the first to promote Hydroinformatics as a discipline and as a programme. Find out more about the IHE Hydroinformatics Masters Course at: www.ihe.nl/education/masters/hi.htm
