Predictive geochemical and limnologic modeling of pit lakes is an important aspect of modern mine-site permitting. One of the key assumptions of many predictive pit-lake models is that open-pit high walls and in-pit backfill become geochemically unreactive once submerged by the filling pit lake. Existing pit lakes provide useful data to test this assumption.

Limnology also called freshwater science, is the study of inland waters.It is often regarded as a division of ecology or environmental science.It covers the biological, chemical, physical, geological, and other attributes of all inland waters (running and standing waters, both fresh and saline, natural or man-made).This includes the study of lakes and ponds, rivers, springs, streams and wetlands.

Apr 01, 2015 · Generally speaking, a lake is a large inland body of water that remains relatively stationary (unlike a river). Lakes come in a wide variety of shapes (e.g. , , ) and colours (e.g. , , , ).Because the world is a complicated place, there are many, many mechanisms by which a lake can form (at least 76, according to some guy named Hutchinson).Let's look at some of them.
