Land subsidence reversal in the Delta of the Sacramento-San Joaquin rivers (CA)
I am working on a project concerned with land subsidence reversal in the Delta of the Sacramento-San Joaquin rivers in central California. Subsidence on peat islands (protected by levees) in the Delta has caused the land-surface elevations to decrease to below sea level. We are studying ways to reverse the effects of subsidence on these peat islands. If anyone knows of publications concerned with similar problem and techniques for reversing the effects of land subsidence, I would be grateful to hear from you.

Pressure Transients in Urban Water Systems:
An EU Thematic Network "Surgenet" has been established to facilitate international communication, cooperation and development in the field of Fluid Transients/Unsteady Flow/Pressure Surges in Pipe Systems. The original 19 partners, representing a range of industries, would warmly welcome other Members who feel that they might benefit from being in closer contact with colleagues in this discipline community.
For information please contact the Coordinator through Christine Burdon at c.e.burdon@ncl.ac.uk

As one aspect of the Network, IAHR Member Dr. Sandy Anderson of the University of Newcastle upon Tyne, UK is preparing a state-of-the-art review on "Potential Causes of High Pressure Transients in Urban Water Systems" for presentation at the forthcoming IAHR/IWA Conference in Valencia in April 2003 as a basis for further wider discussion. He would welcome input on this from as many practitioners in as many countries as possible, so as to ensure that he provides a genuinely international view of the topic. Information about high pressure
transient events, dangerous operation circumstances, relevant papers or reports, appropriateness or limitations of standard software (eg Flowmaster, Wanda, etc), etc can be sent to him at: sandy.anderson@ncl.ac.uk

Modelling of sub sea pipeline flexibility
Does anyone have any experience in the modelling of sub sea pipeline flexibility? A pipeline is to be modelled under the affect of wave forces and an accurate scaling of the pipe's stiffness is required. I do not know the model scale as yet but it will be undistorted. Possible guidelines to similitude criteria or any dimensional analysis for scaling the elastic properties of a pipeline would be very valuable.

Advanced Series on Ocean Engineering – Vol. 19
Saving America’s Beaches
The Causes of and Solutions to Beach Erosion
By Scott L Douglass (University of South Alabama, USA)
Publisher: World Scientific; ISBN 981-238-097-3; Price: US$28; Publication date: August 2002
This book tells you where beach sand comes from, how waves are formed and how they break and move sand down the coast, how “works of man” have blocked this movement and caused beach erosion, and what can be done to save the beaches for future generations of Americans. A three-part prescription for healthy beaches is proposed: “backing off”, “bypassing sand”, and “beach nourishment”.

Flood pulsing in the Wetlands Restoring the Natural Hydrological Balance
By Beth A. Middleton
Publisher: John Wiley; ISBN: 0-471-418072-2; Price: $120.00
Flood pulsing is a natural hydraulic occurrence in ecosystems of rivers, streams, and cypress swamps, and plays an important role in seed dispersal that leads to successful long term restoration. This book bridges the information gap between universities, the public, and private sectors by presenting timely and useful research in an area of restoration where until recently, there has been very little information. You'll find coverage on current research for specific wetland types, which includes a historical and applied approach and case studies from actual restoration projects.

Proceedings of the Conference on Flood Defence 2002
Edited by Baosheng Wu, Zhao-Yin Wang, Guangqian Wang, Gorden G. H. Huang, Hongwei Fang, Jinchi Huang
Price: printed volume US$100; CD-ROM US$10
The two volumes of proceedings contain the keynote and invited lectures and selected papers presented in the Second International Symposium on Flood Defence held in Beijing, China on September 10-13, 2002. The Symposium provided a forum for reviewing the state-of-the-art of studies on flooding and engineering and non-engineering strategies for flood control. It focused on a better understanding of flooding and environmental problems, different perspectives evolved, climate change and its impact on extreme hydrological events, and reporting new approaches to the study and flood control strategies.

Oberwolfach Workshop on Recent Developments in the Mathematical Theory of Water Waves.
The last decade has seen vigorous activity in mathematical theory for the motion of water waves by several independent international research groups, and in 2001 a workshop on mathematical problems of nonlinear hydrodynamic waves was held at the conference centre at Oberwolfach, Southern Germany. The aim of this workshop was to bring these groups together and to focus attention upon certain famous and still outstanding open problems in water waves. These aspects pose considerable challenges and are of importance far beyond the hydrodynamic application in which they emerge.
The October 2002 issue of the Royal Society of London Philosophical Transactions: Mathematical, Physical and Engineering Sciences contains Papers - for more information visit:

Visiting Researcher Post, UK
HR Wallingford has been awarded a Marie Curie Industry Host Fellowship to support a visiting researcher. The research post is to understand the requirements for, and implement, the environmental measurement (ecological and chemical) of SuDS Retention Ponds; evaluate their management needs, and appraise their Whole Life Costs.
This work would contribute towards understanding the potential for such systems to mitigate against the impacts of development, and thus an assessment of the impact of traditional urban drainage on streams would also be required. The work requires a researcher with post-graduate qualifications related to environmental freshwater water quality measurement, preferably with experience in field data collection and biological index models. The candidate will also preferably have an understanding of urban drainage pollution issues and the current drainage developments in Best Management Practices.
