M GABIONS 



Gabions are wire baskets filled with 

 rocks, that are wired together to form 

 a continuous bank stabilization struc- 

 ture. Gabions can be used instead of 

 concrete in areas of limited right-of- 

 way, where the stream has been 

 forced into a narrow passage by en- 

 croachment of structures, and where 

 the channel banks are too steep for 

 other kinds of protection. Gabions are 

 flexible and porous and can eliminate 

 hydrostatic pressure by allowing bank 

 seepage. Their use is promoted by the 

 Stream Restoration Program only if 

 tlu\ suppon revegetation of the 

 channel. The gabions should have 

 soil packed in with the rocks and be 

 pi, mted wiih cuttings of native 

 riparian species. Fihei cloth can be 

 used il needed to help retain die soil. 

 As the vegetation matures, the 

 durability and permanc} of the 

 installation increases.
