They look like the drainage hoses for your hatch...Never seen them under the car just loose like that before. Could be wrong but thats what they look like to me.
i think its the angle of the pictures, pour a little water in the pockets and see if it drains out, if the car has been neglected it might be a good idea to flush those with a hose to get them nice and clean
