Standing water on soils in closed depressions. Unless the soils are artificially drained, the water can be removed only by percolation or evapotranspiration.
A type of drainage management which allows natural depressions to serve as temporary water-holding areas until the pumping system can pump the water away. If these ponding areas are improved, they should be called storage areas or reservoirs.
The pooling of rainwater in a roof depression; also called bird baths.
Pooling of undrained water on a roof.
The process, occurring after a rainfall, when water gathers in low lying areas throughout a watershed and never makes it to a bayou or creek. Back
accumulation of a small body of water.
Water that has accumulated in a low area.
Jetting or the use of water to hasten the settlement of an embankment - requires the judgment of a soils engineer. In hydraulics, pending refers to water backed up in a channel or ditch as the result of a culvert of inadequate capacity or design to permit the water to flow unrestricted.
The collection of water on driveways, walkways, or lawns. Ponding for excessive periods of time is indicative of grading problems.
The term used to describe a pool of water at least 1/2" deep that remains in an area at least 100 square feet for one full day (24 hours) after a rain.
The surface accumulation of water in low-lying or poorly drained areas of a roof. If ponding is excessive, the weight may result in a load which exceeds the design capacity of the structure, or possibly cause premature deterioration of the membrane.
The variation of daily water flows above and below the weekly average flow (for instance, average weekday flow higher than average weekend flow), primarily due to hydroelectric generating operations. ( variation hebdomadaire)
the collection of water in an enclosed area; the development of small ponds or large puddles, resulting from settlement or erosion
The collecting of water in shallow ponds on the top surface of roofing. Certain roofs are designed for the ponding of water to a shallow depth over the whole surface of the roof deck, to aid in summer cooling and as fire protection. French (Formation de flaques)
The puddling of water on a site or its improvements due to improper water sheet flow.
The gathering of water at low or irregular areas on a roof.
The excessive accumulation of water at low-lying areas on a roof.
This involves establishing a steep enough pitch, properly spaced bows or rafters, as well as maintaining a taut fabric, so draining water or melting snow cannot cause the fabric to sag and collect water on the surface.
a roof surface that is incompletely drained.
The collecting of water in shallow ponds on the top surface of roofing. Certain roofs are designed for the ponding water to a shallow depth over the whole surface of the roof deck, to aid in summer cooling. Many flat roof systems void their warranties if ponding water sits on the deck for more than 48hrs.
A water pool created by improper drainage or a depression in, the roofing surface, which is lower than the drain.
A condition where water stands on a roof for prolonged periods due to poor drainage and/or deflection of the deck.
The retention of water on a roof when run-off is hampered.
the collection of water at a low point of a paved surface
1. Accumulation of water that doesn't ever completely drain off a surface, which is caused by not having a proper slope or having depression in the surface. 2. To cure concrete by covering the surface with water.
