Friends of missing mother-of-two Nicola Bulley say they hope the help of a specialist underwater rescue team will give her family answers.
Private diving team Specialist Group International, led by forensic expert Peter Faulding, will help police search for Ms Bulley, who vanished while walking her dog near the River Wyre in Lancashire more than a week ago.
Police have been working on the theory the 45-year-old fell in the river but her family and friends have questioned that, saying there is still no evidence.
