Hydraulic engineering is a critical field related to water resource management, flood control, drought resistance, and ecological protection. Geotextiles, as a versatile synthetic material, play a significant role in hydraulic engineering. With their excellent properties of separation, filtration, drainage, and seepage prevention, geotextiles have become an indispensable material in hydraulic facilities such as dams, reservoirs, and canals.

1. Dam Reinforcement and Seepage Prevention

In dam engineering, geotextiles can be used inside or on the surface of the dam to provide reinforcement and seepage prevention. They effectively prevent water infiltration, reduce pore water pressure within the dam, and enhance its stability. Additionally, geotextiles improve the dam’s resistance to scouring, extending its service life.

2. Seepage Prevention in Reservoirs and Storage Ponds

Seepage prevention is a critical issue in reservoirs and storage ponds. Geotextiles can be laid at the bottom and slopes of reservoirs to form an impermeable layer, preventing water leakage and ensuring effective water storage. Moreover, geotextiles can filter sediment, maintaining water quality.

3. Canal Lining and Drainage

In irrigation or drainage canals, geotextiles can be used in the lining layer to provide separation and drainage. They prevent the mixing of soil and canal materials while offering excellent drainage properties, avoiding damage caused by water accumulation.

4. River Regulation and Bank Protection

In river regulation projects, geotextiles can be used in bank protection structures to prevent soil erosion caused by water flow. They also create a foundation for vegetation recovery, promoting the restoration of riverbank ecosystems.

5. Application in Flood Control Projects

In flood control projects, geotextiles can be used in temporary or permanent flood walls, cofferdams, and other structures to provide reinforcement and seepage prevention. They effectively disperse the impact force of water flow, enhance structural stability, and offer reliable support for flood control efforts.

6. Wetland and Ecological Restoration

Geotextiles are also widely used in wetland protection and ecological restoration projects. For example, laying geotextiles at the bottom of wetlands can prevent water leakage while providing a stable environment for vegetation growth, promoting the restoration of wetland ecosystems.

In summary, the application of geotextiles in hydraulic engineering not only improves project safety and efficiency but also provides technical support for water resource management and ecological protection. Their versatility and cost-effectiveness make them an essential material in hydraulic engineering.
