by P. LE DELLIOU, Chairman of the Committee of the Register and Documentation
The World Register on Dams (WRD) is a magnificent source of information for design, construction, scientifical work and statistical evaluations. It gives reference on dams of the world. It is one of the pillars of the international dam community and a show window to public with very high importance as well for ICOLD as for the National Committees in member and non-member countries.
Committee members work hard to complete the ongoing process of updating, to correct data that may be wrong, to add data to new fields ...
While every care has been taken by the National Committees and rapporteurs in collecting and recording the information furnished, neither the Central Office of ICOLD nor the National Committees and rapporteurs can take any responsibility for any errors or omissions which might have occurred in the Update 2006 of the WRD. We owe our apologies to those who may feel slighted due to such errors or omissions.
My sincere thanks to the members of the committee, the general secretariat of the ICOLD, which ensures the online availability of data, all those responsible in the national committees and also those who participated in the collection.
