Gravity dams are dams which resist the horizontal thrust of the water entirely by their own
weight.
Concrete gravity dams are typically used to block streams through narrow gorges.
Because it is there weight holding the water back, concrete gravity dams tend to use a large
amount of concrete. This can be expensive. But many prefer its solid strength to arch or
buttress dams.
