<p>Qigui Yang is “National Engineering Survey and Design Master”, professorate senior engineer, doctoral supervisor, currently is chairman of the board of CISPDR Corporation, “Young and Middle-aged Expert with Outstanding</p><p>National Contributions”, and the winner of the First National Innovation Competition Award. He has long been engaged in the design of embankment dam and geotechnical engineering, risk assessment and research of emergency rescue technology of barrier lake. He proposed risk assessment methods of barrier lake and built a</p><p>technical system of emergency response, which fills the gap in barrier lake emergency response technology at home and abroad. He is responsible for or participate in more than 30 national research projects and engineering research projects. He successfully removed the risk of the Tangjiashan barrier lake, which was praised by the General Command of the State Council for earthquake relief as "a miracle of handling large barrier lakes in the world". He has been crowned the National Award for Science and Technology twice (ranked</p><p>1st and 2nd), honored with 2 Provincial and Ministerial Science and Technology Progress Special Awards (all ranked 1st), 5 first Awards;1 National Excellent Engineering Survey and Design Gold Award, 2 Silver Award. He is the holder of 25 Chinese Invention patents (12 items ranked 1st), 14 International Invention patents (6 items ranked 1st), and wrote 7 technical standards (2 items ranked 1st). He is also the author/coauthor of more than 80 research papers, and the first author of 5 books.</p><p><br></p><p>Wenjun Yang is a professorate senior engineer and doctoral supervisor.

He is</p><p>national level candidate for the "The New Century Talents Project"</p><p>and the first ministerial level candidate for the "5151 Talents</p><p>Project" of the Ministry of Water Resources. He won the Outstanding Youth</p><p>Award of the Chinese Hydraulic Engineering Society and the First Zhang Guangdou</p><p>Outstanding Youth Award. He has been long engaged in technical research on</p><p>hydraulics and river dynamics, water environment and ecological water</p><p>conservancy, and water and sediment measurement technology. He presided 2</p><p>scientific and technological support projects during the 11th Five-Year Plan,</p><p>and was responsible for one National Key Research and Development Project</p><p>during the 13th Five-Year Plan, three science and technology projects such as</p><p>major scientific research instrument development projects and general program</p><p>of the National Natural Science Foundation of China. He has been crowned the</p><p>National Science and Technology Progress Award three times, and awarded the</p><p>National Engineering Design Gold Prize, 7 Provincial and Ministerial Science</p><p>and Technology Progress First and Special Prizes. He is the first author of 4</p><p>books, the co-author of 3 technical standards. He is also the holder of more</p><p>than 20 invention patents, and the author/coauthor of more than 100 research</p><p>papers.</p>

This book introduces emergency management of barrier lakes systematically,<p>including theories and practices, risk assessment under extremely high-risk</p><p>conditions, evolution of outburst floods, analysis of anti-impact stability, and</p><p>emergency management technology and assessment of risk elimination effect.</p><p>It takes the Tangjiashan barrier lake as a successful case study to</p><p>illustrate effective treatment of barrier lake with high risks, poor environmental</p><p>conditions, extremely urgent rescue time and high disposal difficulties. It</p><p>retains a large number of images and data of great research value for the lake</p><p>risk assessment and building technological emergency system. It provides a</p><p>reliable reference for the government, scientific researchers and survey and</p><p>design team to deal with the sudden natural disaster in barrier lakes,</p><p>especially caused by huge earthquake.</p>

Provides valuable lessons learned from the emergency management of barrier lake Reputed to be “A miracle in the hazardous management of large barrier lakes in the world” Shares abundant images and data of the Tangjiashan barrier lake with rich research value for future reference
