The development and control of the river-ways concerns the technology of laying protective layer,with permanent protective function,on sections.The ston gabion can control water flowing volume and protect water resource from running off in holding the neigh-boring water resource and protecting and controlling the zoolory.
Main Characteristics of Water conservancy:
1. General evolution of watercoursesl approach

2. Bioengineering: a globa
3. Gabion gravity structures
4. Weirs
5. Groynes
6. Strengthening the stability of the river beds
7. Protecting riverbeds from being washed away
8. Providing the prefixed value of coarseness modulus of river banks
