A valley or low place; a tract of low, and usually wet, land; a moor; a fen.
A gutter in a candle.
A slight depression, sometimes swampy, in the midst of generally level land.
A grass covered, broad and shallow depression which leads water overland from drained surfaces to a storage or discharge system. They provide temporary storage for storm water and reduce peak flows.
n. (Sw. sval, cool) a hollow or depression, especially one in wet, marshy ground.
a ditch or valley in the earth
1. A low tract of land, especially when moist or marshy. 2. A long, narrow usually shallow trough between ridges on a beach, running parallel to the coastline. 3. A shallow troughlike depression that carries water mainly during rainstorms or snow melts.
A depression or dip in the ground.
This grassy depression leads run-off to a storage area, like a retention pond, or other surface water. The grass is meant to filter and slow the water being discharged into the watercourse.
A slight, open depression which lacks a defined channel that can funnel overland or subsurface flow into a drainageway.
A linear hollow or depression found between dunes or beachridges. Generally marshy or swampy, or may contain small lakes.
A depression or low place on the course.
a channel or a sloped surface that directs the flow of storm water runoff. Swales can be vegetated, lined with vegetation that slows and filters flows when depths are shallower than the vegetative height, or paved.
wide low depression.
An open drainage channel designed to detain or infiltrate stormwater runoff.
A natural or constructed open drainage channel that is used to intercept and carry surface storm runoff.
Valley between dunes.
use of ground contours to direct water drainage or flow.
A slight depression, often for drainage, in the midst of generally level land.
a "depression in the earth
a long narrow depression, which varies in depth from six inches to a few feet and is typically wider than it is deep
a low-lying or depressed and often wet stretch of land
a marshy depression in a tract of land, usually rolling prairie
a nice name for a wide, shallow ditch
a permanent broad depression that can be built in your yard to carry water more directly where you want it," Sjolander explains
a shallow gully that will vary in size but is about a foot or so deep and two to three feet wide
a shallow gutter-like ditch that carries off surface water
a small valley that channels surface water off the property
a wide shallow ditch that has been dug along the street and sometimes beside and behind the property
The soil contour on a building lot deliberately shaped to channel rainwater away from the home.
Shallow open earth channel used to intercept and route surface water flows to a discharge location.
A depression in the ground. It is designed to channel rain and irrigation water along its path and toward the street.
A ditch cut into the soil, intended to collect and divert rainwater , snow, melt, etc.; used with septic systems to direct water away from the leaching bed.
a natural or graded unpaved gentle depression or flow line acting as a gutter or ditch
a wide, shallow ditch or depression used to temporarily convey, store, and filter runoff. See Prairie Swale.
A drainage channel formed where two slopes meet.
A wide, shallow depression in the ground designed to channel drainage of rainwater.
A natural depression or wide shallow ditch used to temporarily convey, store, or filter runoff.
A natural or human-made open depression or wide, shallow ditch that intermittently contains or conveys runoff. Can be used as a BMP to detain and filter runoff.
A linear low-lying natural topographic drainage feature running downhill and crossing the trail alignment in which sheet runoff would collect and form a temporary watercourse. A low-lying ground drainage structure (resembling a swale) can be constructed to enhance drainage across the trail.
A shallow depression in the ground for storm water drainage.
A linear level-floored open depression excavated by wind or formed by the build-up of two adjacent ridges. Typically associated with the depression between two adjacent sand dunes.
A moderately contoured depression or dip in terrain.
An elongated depression in the land surface that is at least seasonally wet, is usually heavily vegetated, and is normally without flowing water. Swales conduct stormwater into primary drainage channels and may provide some groundwater recharge.
A low laying or depressed, at least seasonally wet stretch of land. Often lined with grass (grassy swale) and used as a conveyance for storm water.
a shallow depression in the land's surface which may be filled with water. In karst terrain it may indicate an incipient sinkhole forming.
A WIDE SHALLOW DEPRESSION FOR THE PURPOSE OF CHANNELING WATER.
A shallow vegetated channel designed to conduct and retain water, but may also permit infiltration; the vegetation filters particulate matter.
A linear hollow or depression found between dunes or beach ridges, and is generally marshy or swampy and heavily vegetated.
A constructed or natural drainage channel used to direct surface flow. Constructed swales have parabolic, trapezoidal, or triangular cross sections.
A low area or depression.
A low-lying, often depressed and swampy, area of land; an open ended swale can be created for use as a land drainage device.
A shallow depression or dip in the terrain
A swale is a low tract of land, especially when moist or marshy. The term can refer to a natural landscape feature or a human-created one. When created by humans, this open drain system is designed to manage water runoff.
