A319 Captain reported receiving a nosewheel steering warning during climbout. The crew continued to their destination and had no nosewheel steering during landing.

Narrative

Upon gear retraction we received a WHEEL- N/W STRG FAULT ECAM. We decided to continue to ZZZ1 after running the QRH checklist. Checklist indicated that operation would be normal and steering would be possible with differential braking. After confirming our plan with dispatch and Maintenance Control we continued to ZZZ1 and coordinated with approach and tower for a runway with a high-speed taxiway to help clear the runway if we had no N/W steering after landing. We also asked dispatch to pre-coordinate for a tug in case we could not safely steer the aircraft on the taxiway. Maintenance control indicated that we had a channel one failure of the Brake Steering Control Unit (BSCU) and that when we lowered the gear we would most likely get the steering back with channel two. After lowering the landing gear; we received the same ECAM indicating we would have no N/W steering with BSCU channel two either. The First Officer made the landing; and I took control of the aircraft at 60 kts. I confirmed there was no nosewheel steering available and cleared the runway on one of the high-speed taxi ways of RWY XX R using differential braking. The aircraft could not be safely taxied using just differential braking; so I decided to set the brakes and call for a tug to be towed in.
