The Third International Workshop on Long-Term Behaviour and Environmentally Friendly Rehabilitation Technologies of Dams, LTBD2015, was held at Hohai University in Nanjing, China, from October 17 to 19, 2015. It was the aim of the LTBD2015 Workshop to provide an opportunity for high level scientists, engineers, operators and young PhD students to present and exchange their experiences and the latest developments related to the design, performance, rehabilitation and environmental aspects of earth, rockfill and concrete dams. The papers included in this workshop were related the the following subtopics:

• Methods of Design and Analysis of Earth, Rockfill and Concrete Dams
• Dam Monitoring, Instrumentation and Safety Assessment
• Properties of Construction Materials for Dams and their Constitutive Modelling
• Seismic Aspects and Earthquake Analysis
• Maintenance, Rehabilitation and Heightening
• Long-term Mechanical and Seepage Behaviour of Dams
• Environmental-friendly Reinforcement Materials for Hydraulic Structures
• Technologies for Preventing the Deterioration and Cracking of Concrete Dams
