It didn't; Submarine Sonar wasn't developed until the '30's, and during WWII it saw limited use aboard submarines. Back then, it was essentially a bearing / speed indicator for a target, but not much more.
No, sonar didn't affect the outcome of World War I. Sonar and electronics technology were not far enough advanced to make a difference in the era from 1910 to 1920. Certainly the war spurred the efforts to develop sonar, but it didn't come far enough fast enough to have any significant effect on WWI at all. A link is provided to the Wikipedia article on sonar, and the section on "History" is brief and easy to read. Why not surf on over and check it out? Our friends there supply knowledge for free.
