Narrative:
When the gear handle was placed down for landing; the green hydraulic system depleted of fluid and lost pressure. The landing gear did come down and locked and we were able to get landing flaps (full). The first officer then made a normal landing. Tower was advised there may be delay clearing runway due to inoperative nosewheel steering. We were able to clear the runway but 1 aircraft behind us was sent around. We stopped the aircraft and requested a tow to the gate. The tow to gate was accomplished without further incident. Maintenance investigation revealed a hole in a flex hydraulic line on the landing gear down side.
