With Nepal’s mountainous terrain and monsoon-driven rivers, flood control and river training are vital to protect settlements, farmlands, and infrastructure. These works help stabilize riverbanks and reduce erosion during high flows.
Types of River Training Works
- Gabion Retaining Walls: Wire-mesh boxes filled with stones to control scouring.
- Spurs and Groynes: Structures extending into the river to divert flow away from banks.
- Check Dams: Used in small streams to reduce velocity and trap sediment.
- Embankments: Earthen or masonry structures to contain floodwaters.
Challenges in Nepal
- Unstable slopes and landslides during monsoon
- Difficulty transporting materials to remote river sites
- Frequent design changes due to shifting river morphology
Role of Contractors
Skilled contractors like Jwala Nirman Sewa execute river training works using gabion, masonry, and earthworks equipment to protect lives and properties in flood-prone regions of Gandaki and other provinces.
