A dry lake bed, also known as a playa (/ ˈ p l aɪ-ə /), is a basin or depression that formerly contained a standing surface water body, which disappears when evaporation processes exceed recharge. If the floor of a dry lake is covered by deposits of alkaline compounds, it …

Playa, flat-bottom depression found in interior desert basins and adjacent to coasts within arid and semiarid regions, periodically covered by water that slowly filtrates into the ground water system or evaporates into the atmosphere, causing the deposition of …

A playa is a dry, vegetation-free, flat area at the lowest part of an undrained desert basin. It is a location where ephemeral lakes form during wet periods, and is underlain by stratified clay, silt, and sand, and commonly, soluble salts.

Playa—originally a Spanish word meaning “shore” or “beach,” now denoting in English the flat-floored bottom of an interior desert basin on which smooth, barren, sun-baked microrelief prevails. It is essentially the dry lake remnant of a former base …

These dry lake basins, often found in arid regions, are vital geological features with significant implications for the oil and gas industry. What is a Playa? A playa, also known as a playas lake, salina, or alkali flat, is a flat, dry lakebed that forms in closed depressions within desert regions.

2000年5月1日 · 1) Playa: a discharging intracontinental basin with a negative water balance, remaining dry 75% of the year, and often associated with evaporites. 2) Playa lake: a transitional category between playas and lakes, essentially a flooded playa as defined above.

Playa basins contain saline lakes and the evaporitic mudflats around them. However, playa basins can be different if they are fed by marine incursions, dominated by perennial lakes of brackish or fresh water, or dominantly dry. A discrimination of playa types, which originated under such different conditions, can be difficult in the rock record.

1994年1月1日 · In this paper a playa is defined as an intracontinental basin where the water balance of the lake (all sources of precipitation, surface-water flow, and groundwater flow minus evaporation and...

2016年10月10日 · In two experiments, outerbasin and annulus infiltration were evaluated in addition to playa basin infiltration. For these experiments, playa basin infiltration rates significantly exceeded those of their outerbasin counterparts. The implications are that environmental pollution can occur if the playas are not properly managed.

2013年7月2日 · Playa, also called pan, flat, or dry lake, flat-bottom depression found in interior desert basins and adjacent to coasts within arid and semiarid regions, periodically covered by water that slowly filtrates into the ground water system or evaporates into the atmosphere, causing the deposition of salt, sand, and mud along the bottom and around ...
