Dams hold back water up to the level that they were designed for. They control/regulate the flow of water. Flood waters that come down rivers can be held back (up to the design point) from devastating places further down river. Coastal/sea flooding would not be stopped by dams - but sea walls and the like. Still, preventing river flood waters adding to coastal flooding might help the situation.
