On behalf of the Local Organizing Committee, it is our great honor to invite you to the 16^th Congress of Asia and Pacific Division of International Association of Hydraulic Engineering and Research and the 3^rd IAHR International Symposium on Hydraulic Structures to be held in Nanjing October 20-23, 2008.

The ever increasing demands on water resources through the rapid development of human society have brought about serious challenges. This means that the role of hydraulic engineering has become more important than ever before. These conferences with the main theme of "Water and Humanity — Friendship, Harmony and Sustainable Development" will offer you high quality scientific programs as well as memorable social activities.

Located on the south bank of the Yangtze River, Nanjing, the capital of Jiangsu Province, is one of the most delightful Chinese cities. Known as the Ancient Capital of the Six Dynasties in China's history, Nanjing has a brilliant cultural heritage. The Congress and the Symposium will provide the delegates from all over the world with an open forum to exchange their research results, new information and ideas in the fields related to hydro-environment. Participants of both events will be fortunate to witness a dynamic harmony of 5,000 years of Chinese heritage, with modern civilization, in addition to vivid development of water projects. We are eagerly in anticipation of receiving your valuable contribution and active participation for the success of both events. We look forward to welcoming you in Nanjing.
