Time of ponding

Last updated

Time of ponding is a term used in hydrology and refers to the instance when a land surface becomes saturated (from rain) and ponding of water occurs. [1]

Terminology is the study of terms and their use. Terms are words and compound words or multi-word expressions that in specific contexts are given specific meanings—these may deviate from the meanings the same words have in other contexts and in everyday language. Terminology is a discipline that studies, among other things, the development of such terms and their interrelationships within a specialized domain. Terminology differs from lexicography, as it involves the study of concepts, conceptual systems and their labels (terms), whereas lexicography studies words and their meanings.

Hydrology The science of the movement, distribution, and quality of water on Earth and other planets

Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is a hydrologist, working within the fields of earth or environmental science, physical geography, geology or civil and environmental engineering. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management.

Rain liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated

Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.

Water garden

Water gardens, also known as aquatic gardens, are a type of water feature. They can be defined as any interior or exterior landscape or architectural element whose primary purpose is to house, display, or propagate a particular species or variety of aquatic plant. The primary focus is on plants, but they will sometimes also house ornamental fish, in which case the feature will be a fish pond.

Body of water Any significant accumulation of water, generally on a planets surface

A body of water or waterbody is any significant accumulation of water, generally on a planet's surface. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.

Riparian forest forested or wooded area of land adjacent to a body of water

A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, sink or reservoir.

River Arrow, Worcestershire river in Worcestershire, United Kingdom

The River Arrow is a tributary of the River Avon, which flows through Worcestershire and Warwickshire in the English Midlands.

Groundwater recharge groundwater that recharges an aquifer

Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and, is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally and through anthropogenic processes, where rainwater and or reclaimed water is routed to the subsurface.

Mareza is a river in Montenegro. It is also a name of suburb of Podgorica, in which the river originates.

In hydrology, oasification is the antonym to desertification by soil erosion; this technique has limited application and is normally considered for much smaller areas than those threatened by desertification.

Dambo is a word used for a class of complex shallow wetlands in central, southern and eastern Africa, particularly in Zambia and Zimbabwe. They are generally found in higher rainfall flat plateau areas, and have river-like branching forms which may be nowhere very large, but common enough to add up to a large area. For instance, dambos have been estimated to comprise 12.5% of the area of Zambia. Similar African words include mbuga, matoro (Mashonaland), vlei, fadama (Nigeria), and bolis ; the French bas-fond and German Spültal have also been suggested as referring to similar grassy wetlands.

Mount Joy Pond Natural Area Preserve

Mount Joy Pond Natural Area Preserve is a 274-acre (1.11 km2) Natural Area Preserve located in Augusta County, Virginia in the United States. Located on the western side of the Blue Ridge Mountains, it supports a large population of the rare Virginia sneezeweed. This and other plants are associated with a large sinkhole pond, the centerpiece of the property; fewer than two dozen such ponds remain in Augusta and neighboring Rockingham County. Much of the surrounding landscape consists of hardwoods and pines.

Stream A body of surface water flowing down a channel

A stream is a body of water with surface water flowing within the bed and banks of a channel. The stream encompasses surface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls.

Andrews Creek is a glacial meltwater stream which flows south along the east margin of Canada Glacier into the west end of Lake Fryxell, in Taylor Valley, Victoria Land. The name was suggested by hydrologist Diane McKnight, leader of a United States Geological Survey (USGS) team which made extensive studies of the hydrology and geochemistry of streams and ponds in the Lake Fryxell basin, 1987–94. Named after USGS hydrologist Edmund Andrews, a member of the field team who studied glacier hydrology during the 1987–88 and 1991–92 summer seasons.

Many Glaciers Pond is a pond, 0.3 nautical miles (0.6 km) long, located 0.5 nautical miles (1 km) south of the snout of Commonwealth Glacier in Taylor Valley, Victoria Land, Antarctica. The pond is part of the Aiken Creek system and receives drainage from several glaciers including Commonwealth Glacier, Wales Glacier and the unnamed glacier next westward. The name was suggested by United States Geological Survey (USGS) hydrologist Diane McKnight, leader of USGS field teams that studied the hydrology of streams entering Lake Fryxell, Taylor Valley, over the period 1987–94.

Spaulding Pond is a pond 0.3 nautical miles (0.6 km) northeast of the terminal ice cliff of Howard Glacier in Taylor Valley, Victoria Land. The name was suggested by Diane McKnight, leader of United States Geological Survey (USGS) field teams which studied the hydrology and geochemistry of streams and ponds in the Lake Fryxell basin, Taylor Valley, 1987-94. Named after USGS hydrologist Sarah Ann Spaulding, a member of the team during two seasons, 1988–89 and 1991–92, who studied the pond.

Law Brook, Surrey

The Law Brook or Postford Brook is a Surrey stream, a tributary of the Tillingbourne which in turn flows into the River Wey. It is notable in its own right chiefly for its industrial heritage.

Waterway trail on the Moosalbe

The Waterway trail on the Moosalbe is one of seven themed walks on the subject of hydrology in the German state of Rhineland-Palatinate. The path runs for over 33 km along the Moosalbe and Hirschalbe streams through the Palatine Forest and has 23 way stations.

The Uzboi-Landon-Morava (ULM) outflow system is a long series of channels and depressions that may have carried water across a major part of Mars. It starts with channels that drain into the Argyre basin in the Argyre quadrangle. Water ponded in the Argyre basin, then the overflow is believed to have traveled northward through Uzboi Vallis, into Landon basin, through Morava Valles, to the floor of Margaritfier basin. Some of the water may have helped to carve Ares Vallis. Altogether, the total area drained for this watershed may have been about 11 X 106 km2 or about 9% of Mars.
