Rivers are invaluable for city settlement, as they supply fresh water and enable the Water Mill to be built. With it, any city may get a good start at growing and producing as early as the Ancient Era! An Aqueduct built next to it will also supply a nearby city with Fresh Water for Housing Housing purposes.
But rivers do more than that. They provide a bulwark against invasions for any commander that knows how to use them; they turn Desert into paradise by enabling the Floodplains feature; elsewhere they allow improved farming with the Civil Engineering Civic; they improve Commerce thanks to the additional transport opportunities they provide for merchants.
