Flood plains are a terrain feature found on flat desert tiles which are adjacent to rivers. While unimproved deserts normally provide no resources whatsoever when worked, deserts with flood plains produce +2 food, the same as grassland, and can support farms. A civilization which begins near a large desert with a river can benefit greatly from the food provided by flood plains in an area which would otherwise be unsuitable for developing large cities.
Flood plains are low-lying areas adjacent to rivers. Every year the river floods, providing natural irrigation and rich nutrients to the land, making flood plains incredibly fertile and the most productive farmland in the world. Ancient Egypt owed most of its wealth and power to the annual flood of the mighty Nile river.
