This volume compiles the selected papers from the 7th International Conference on Advances in Civil and Ecological Engineering Research (ACEER 2025), held from July 21 to 24, 2025, in Matsue, Japan. The conference brought together leading experts, researchers, and practitioners from around the world to present their latest findings and innovations in civil, environmental, and ecological engineering. The book covers a wide range of topics, including construction engineering and management, hydraulic and hydrologic engineering, air quality and atmospheric pollution, ecological risk assessment and management, environmental restoration and protection, water pollution control and treatment, water resources engineering, waste utilization in construction, and green building practices. It also explores cutting-edge technologies aimed at fostering sustainable cities and resilient infrastructure, addressing key sustainability challenges in civil engineering. Each chapter offers valuable insights into current research trends, practical applications, and future directions in the field. This comprehensive resource will serve as an essential reference for researchers, practitioners, and engineers working in civil and ecological engineering, providing them with the latest knowledge and tools to tackle complex environmental and infrastructural challenges.

This is not the first edition of the book, and the current volume includes several improvements over previous editions:

• Expanded coverage of emerging topics like waste utilization in construction and green building practices.
• Enhanced focus on sustainability and resilience in urban development.
• New contributors from a wider range of countries and institutions, providing a more global perspective.
