Yes river raids can be repeat as much you want. Their reset is full only after two others river raid done at another location (another river raids map). Not chain two river raids at same location also allow drop down the threat level at the location.

The reset is partial if you did only one other river raid at another location before raid again the same map, the rule is approximately that locations done previously aren't fully reset like won't have loot or/and will have less defenders. The map shows the location not fully reset yet with a X on the location.

They have some unique drops linked to the quests of the river raids, those drops aren't reset, there's also a case of a special combat against a special NPC once done it won't respawn.
