River deltas, such as that of the Nile, Mississippi, and Rhine contain fertile soil washed from upstream. As a result the land is extremely fertile. The land can produce a far higher yield that surrounding land. The annual flooding renews the soil. The ports are frequently fresh water. Ocean going vessels would get rid of wood destroying organisms by docking there.
Of course when the people would not allow the soil to be renewed by the annual floods but in fact would actually remove water from the ground, it would be necessary to surround the land by dams as happened in the lower ninth ward in New Orleans and in Holland.
