A swale is a shady spot, or a sunken or marshy place. [1] In US usage in particular, it is a shallow channel with gently sloping sides. Such a swale may be either natural or human-made. Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration. [2]
[2]: 19 Bioswale design is intended to safely maximize the time water spends in the swale, which aids the collection and removal of pollutants, silt and debris. Depending on the site topography, the bioswale channel may be straight or meander.
Swale (landform), a low tract of land Bioswale, landform designed to remove silt and pollution; Swales, found in the formation of Hummocky cross-stratification;
geosphere - the solid part of planet Earth, the main divisions being the crust, mantle, and liquid core. The lithosphere is the part of the geosphere that consists of the crust and upper mantle. geothermal energy - energy derived from the natural heat of the earth contained in hot rocks, hot water, hot brine or steam. global acres see global ...
Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere , hydrosphere / cryosphere , atmosphere , and geosphere (or lithosphere ).
It is also known as geoscience, the geosciences or the Earthquake sciences, and is arguably a special case in planetary science, the Earth being the only known life-bearing planet. Earth science is a branch of the physical sciences which is a part of the natural sciences. It in turn has many branches.
Ridge and swale, or in dunal areas dune and swale, is a landform consisting of regular, parallel ridges alternating with marshy depressions. [1] Ridge-and-swale landscapes are most commonly formed by the gradual movement of a beach , for example as a result of gradually fluctuating water levels, or the shifting meanders of a river.
The null point theory has been controversial in its acceptance into mainstream coastal science as the theory operates in dynamic equilibrium or unstable equilibrium, and many fields and laboratory observations have failed to replicate the state of a null point at each grain size throughout the profile.
