The Disappearing Walker Lake#

While the loss of the Aral Sea in Kazakhstan and Lake Urmia in Iran have received a lot of attention over the last few decades, this trend is a global phenomena. Reciently a number of papers have been published including one focusing on the Decline of the world’s saline lakes. Many of these lakes have lost the majority of their volume over the last century, including Walker Lake (Nevada, USA) which has lost 90 percent of its volume over the last 100 years.

The following example is intended to replicate the typical processing required in change detection studies similar to the Decline of the world’s saline lakes.
