Recommended environmentally friendly design measures of channels
The measures include (Figures 11 and 12),
- the use of varied bank materials other than concrete such as provision of fabric geotextile reinforced grass lining at side slopes;
- replanting, preferably with native species, along the new channel banks;
- retention of abandoned meanders; and
- creation of aquatic planting bays at channel base of the new river channels.
