Eldritch Sea Canon

A burst of rushing water streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 cold damage and is push back 10 ft.

The spell creates more than one burst of water when you reach higher levels: two bursts at 5th level, three bursts at 11th level, and four bursts at 17th level. You can direct the bursts at the same target or at different ones. Make a separate attack roll for each burst.
