Sink: an endorheic depression generally containing a persistent or intermittent (seasonal) lake, a salt flat (playa) or dry lake, or an ephemeral lake. Panhole: a shallow depression or basin eroded into flat or gently sloping, cohesive rock. [2] Collapse-related: Sinkhole: a depression formed as a result of the collapse of rocks lying above a ...
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
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 is known as an alkali flat.
A study in an arid agricultural region of Arizona [3] showed that, even with a water level recovery of 100 ft after groundwater pumping was stopped, the land surface continued to subside for decades. This is a result of the continued dewatering of aquitards (fine-grain layers that slow the movement of groundwater) from stresses mentioned in the ...
From left to right: a field with a source, a field with a sink, a field without either. In the physical sciences, engineering and mathematics, sources and sinks is an analogy used to describe properties of vector fields. It generalizes the idea of fluid sources and sinks (like the faucet and drain of a bathtub) across different scientific ...
Depending on water losses, precipitation, and inflow (e.g., a spring, a tributary, or flooding), the temporal result of a lake in a sink may change. The lake could be a persistent lake, an intermittent lake, a playa lake (temporarily covered with water), or an ephemeral lake, which completely disappears (e. g. by evaporation) before reappearing in wetter seasons.

[1] Losing streams are common in arid areas due to the climate which results in huge amounts of water evaporating from the river generally towards the mouth. [ 2 ] Losing streams are also common in regions of karst topography where the streamwater may be completely captured by a cavern system, becoming a subterranean river .
The endorheic basin that feeds water into Üüreg Lake, Mongolia NASA photo of the endorheic Tarim Basin, China. An endorheic basin (/ ˌ ɛ n d oʊ ˈ r iː. ɪ k / EN-doh-REE-ik; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into ...
