Human Factors; Procedure
Aircraft X was cleared to land Runway XYR. Aircraft Y called for departure. The call came out of the speaker so I check to see which freq he was on. Local east and west were combined. He was on Local east freq. I cleared Aircraft Y for takeoff on Runway XYL with a right turn. Aircraft Y read the clearance back correctly. I cleared another aircraft to land. I noticed Aircraft Y was turning on to Runway XYR. Aircraft X was on landing roll. I thought it was better to let Aircraft Y continue the departure than stop the aircraft on the runway. Aircraft X exited the runway. Aircraft Y was given the brasher/twr phone number and later switched to correct freq.
I was landing with full clearance on runway XYR; just after touchdown to my surprise I see an aircraft enter XYR; and proceed to take off. At this point my nose wheel was just touching down; I had not yet applied any brakes when I first see this aircraft taxi directly in front of me. I slammed on the brakes and veer hard to the left; while calling Tower to ask if the aircraft departing on XYR is cleared to do so. ATC replies; no it is not; please exit runway. Regarding the distance between myself and the departing aircraft; I don't know for sure; close enough to shake me up for sure.
Aircraft was cleared for takeoff on left runway; but took right runway instead as another aircraft was touching down on the same runway.
