The National Board for Wildlife (NBWL) has given approval to construct training walls at the Pazhaverkadu estuary to stabilise the bar mouth, which often gets closed due to silting.
An official, who was a part of the NBWL meeting held in New Delhi on November 17, confirmed that consent was granted for the construction of two training walls, of 160 m and 150 m each, on either side of the bar mouth.
