Hydraulic Applications
IGS Technical Committee on Hydraulic Applications

The Technical Committee on Hydraulic Applications (TC-H) is dedicated to the scientific and engineering development of geosynthetic systems. This committee promotes the dissemination of knowledge, technology, research findings, design and construction methodologies related to hydraulic applications of geosynthetics, such as drainage, erosion control, and coastal protection in geotechnical and geoenvironmental engineering.

Our Work

The TC-H’s work includes:
