An international conference focusing on civil engineering, hydraulic engineering, and transportation will be held in Mianyang. The conference aims to gather top scholars, engineers, and industry experts from around the world to discuss the latest developments and future directions in these fields. Mianyang, as an important science and technology city in southwestern China, provides an ideal environment for this important academic activity. This conference will focus on three core themes for in-depth discussion: civil engineering, water conservancy engineering, and transportation. In the field of civil engineering, the agenda covers various aspects from infrastructure construction to intelligent building technology, including but not limited to structural health monitoring, the application of green building materials, and the development of urban underground spaces; The water conservancy engineering section focuses on the advancement of water resource management, flood control and drought resistance technologies, and their application in sustainable development; The transportation sector focuses on the construction of intelligent transportation systems, the development of multimodal transportation networks, and the application prospects of new energy transportation vehicles. Specially designed technical seminars and interactive sessions will provide a platform for participants to exchange ideas and share experiences. The Young Scientists Forum is a major highlight of this conference, as it not only provides opportunities for young researchers to showcase their research results, but also promotes direct dialogue between them and senior experts, which is crucial for stimulating innovative thinking and interdisciplinary collaboration. In addition, the conference will organize a series of technical exhibitions and field visits, providing participants with the opportunity to personally experience the practical application cases of leading enterprises and research institutions in civil engineering, water conservancy engineering, and transportation in Mianyang. By visiting these high-tech enterprises, participants can not only gain a deeper understanding of current technological development trends, but also inspire new research ideas and practical directions. During the conference, special lectures and workshops will also be arranged, inviting well-known experts in the industry to provide in-depth explanations and technical training, helping participants improve their professional skills and knowledge level. Both the application of emerging technologies and the solutions to complex problems will be fully discussed and showcased here. This international conference is not only a platform to showcase the latest scientific research achievements and technological breakthroughs, but also an important opportunity to promote international cooperation and exchange. Both researchers seeking partners and professionals seeking to stay informed about the latest developments in the industry will find valuable resources and inspiration here. Let us gather in Mianyang to explore the infinite potential of civil engineering, water conservancy engineering, and transportation, work together to promote technological progress, and create a better future. This conference will undoubtedly become a grand event in the industry, and we look forward to the active participation and contribution of elites from all walks of life to jointly explore how to use advanced science and technology to solve practical engineering problems and promote the sustainable development of the industry. Mianyang is not only known for its technological strength, but its rich natural landscapes and cultural heritage will also bring unique experiences to attendees.
