B. The project performed well with minimal maintenance. Failure from
f l e x i n g because the baskets were not initially tied to the embankment,
resulted in the slight loss of fill material from baskets at the revetment
ends.
DISCUSSION: I n summation, gabions may be useful for certain applications in
t h e coastal environment. However, t h e r e are some critical points to consider.
1. When deciding whether to use gabions, an assessment must be done to
c o n s i d e r the economics associated with their use versus the risks if failure
occurs.
2.
Gabions should not be used in high energy wave environments.
3 . Gabions should not be used in the active surf zone or where large
a m o u n t s of debris are present.
4 . Gabions should not be used on public beaches where injury to bathers
from protruding wire is possible.
5 . The manufacturer deployment recommendations should be adhered to
u n l e s s there is a sound engineering reason for modification.
a comprehensive inspection and maintenance
6 . A f t e r installing gabions,
p l a n should be established.
