Stagnant water can be dangerous for drinking because it provides a better incubator than running water for many kinds of bacteria and parasites. Stagnant water can be contaminated with human and animal feces, particularly in deserts or other areas of low rainfall. [2] Water stagnation for as little as six days can completely change bacterial ...
Lishui ( Chinese: 立水; pinyin: lìshuǐ; lit. 'standing water') or shuijiao ( Chinese: 水脚; Chinese: shuǐjiǎo; lit. 'water feet') is a set of parallel diagonal (either straight or wavy), multicoloured sea-waves/line patterns. [ 1][ 2][ 3]: 100 It originated in China where it was used by the Qing dynasty court prior to the mid-18th ...
Standing water is a type of freshwater habitat that mainly consists of lakes and ponds. This habitat has limited species diversity because they are isolated from one another and other water systems, unlike running water. [7] Standing water experiences the process of stratification, which is when water is layered due to the oxygen content. [6]
Seiche. A seiche (/ seɪʃ / SAYSH) is a standing wave in an enclosed or partially enclosed body of water. Seiches and seiche-related phenomena have been observed on lakes, reservoirs, swimming pools, bays, harbors, caves, and seas. The key requirement for formation of a seiche is that the body of water be at least partially bounded, allowing ...

Clapotis. Incoming wave (red) reflected at the wall produces the outgoing wave (blue), both being overlaid resulting in the clapotis (black). In hydrodynamics, a clapotis (from French for "lapping of water") is a non-breaking standing wave pattern, caused for example, by the reflection of a traveling surface wave train from a near vertical ...
Standpipe (firefighting) A standpipe or riser is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water to the fire. Within the context of a building or bridge, a standpipe serves the same ...
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and ...
