''Sand dams'' is a term used generally to describe a particular type of groundwater dam constructed in sandy river beds, as described above. A slightly different type of '''sand dam''' is where an impermeable dam is built in a river bed that doesn't contain much permeable sediment, to trap sand when the river flow is high, and create an 'artificial aquifer'.
