Project 1.4: Dam Material Characterization and Development of Innovative Construction Materials from Dam Wastes

Dam safety and durability demand a multidisciplinary approach that integrates hydrological, geotechnical, structural, and material engineering. Conventional empirical methods often fall short in capturing the complex interactions between dam materials, site conditions, and long-term performance. Accurate characterization of soils, rocks, sediments, and geosynthetics is therefore critical for risk assessment, rehabilitation, and sustainable construction. This proposal seeks to establish a comprehensive framework for dam material testing and innovation, addressing challenges such as seepage, sedimentation, and waste disposal. A state-of-the-art facility will enable advanced characterization of dam materials, certification protocols, and development of innovative solutions tailored to Indian dams. Key research directions include exploring low-cost, indigenous seepage control methods, valorization of dredged sediments for civil engineering applications, and the design of sediment-filled geocells for slope stabilization, embankments, and erosion control. The project also emphasizes the role of geosynthetics in drainage, filtration, reinforcement, and slope protection, with systematic testing to establish performance guidelines. By combining experimental investigations, computational modelling, and field demonstrations, the study aims to provide design specifications for novel materials and systems that enhance dam resilience. The outcomes will include certification processes, rehabilitation strategies, and sustainable reuse of dam wastes, contributing to reduced environmental impacts and improved safety. Beyond technical advances, the project will support knowledge transfer through guidelines, publications, and collaboration with stakeholders, ensuring long-term benefits for dam infrastructure management in India. Ultimately, the research will bridge material innovation with practical dam engineering, strengthening resilience against climatic, geotechnical, and operational challenges.
