Understanding Flooded Quarries – Outdoor Swimming Society

Flooded quarries vary considerably, from stone quarries – which could have steep sides, rockfalls, debris and possibly industrial pollution or unusually high pH, to old brickworks or clay lakes – which could have beaches littered with bricks, to sand or gravel pits – many of which have gently sloping sandy beaches.

Case Study Groundwater Dams

''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'.
