What is playa?

Playas are flat-bottomed depressions that are sometimes surrounded by water which it slowly seeps into the groundwater system or vaporizes into the atmosphere. As a result, salt, sand, and mud are deposited along the depression's bottom and around its edges.

Some key feature of playa are-

• Playas are also known as pans, flats, or dry lakes.
• They are typically found in inner desert watersheds and close to coasts in arid and semi-arid regions.
• The flattest recorded landforms are playas. Typically, their gradients are less than 0.2 meters per kilometer.
• Many kilometers of surface may be submerged when only a few centimeters of water are added.
• The nearly flawless flatness that is so distinctive of these dry region landforms is developed and maintained by the process of flooding.
• The middle, level basins of arid plains are called playas. They need drainage from the inside to a place where evaporation far outweighs intake.
• A playa lake arises when the area is inundated, concentrating salts and fine-grained debris.
• Playa terminology is somewhat confusing due to the abundance of regional names.
