Sand boil

Sand boils or sand volcanoes occur when water under pressure wells up through a bed of sand. The water looks like it is "boiling" up from the bed of sand, hence the name.

Flood protection structures

Sand boils can be a mechanism contributing to liquefaction and levee failure during floods. This effect is caused by a difference in pressure on two sides of a levee or dike, most likely during a flood. This process can result in internal erosion, whereby the removal of soil particles results in a pipe through the embankment. The creation of the pipe will quickly pick up pace and will eventually result in failure of the embankment.

A sand boil is difficult to stop. The most effective method is by creating a body of water above the boil to create enough pressure to slow the flow of water. A slower flow will not be able to move soil particles. The body of water is often created with sandbags forming a ring around the boil.

During the flood of spring 2011, the United States Army Corps of Engineers had to work to contain the largest sand boil ever discovered. The sand boil measured 30 feet by 40 feet and was located in the city of Cairo, Illinois at the confluence of the Mississippi River and the Ohio River.

Sandō

A sandō (参道, visiting path) in Japanese architecture is the road approaching either a Shinto shrine or a Buddhist temple. Its point of origin is usually straddled in the first case by a Shinto torii, in the second by a Buddhist sanmon, gates which mark the beginning of the shrine's or temple territory. The word dō (道) can refer both to a path or road, and to the path of one's life's efforts. See, Karatedo. c.f. Taoism 道 There can also be stone lanterns and other decorations at any point along its course.

A sandō can be called a front sandō (表参道, omote-sandō), if it is the main entrance, or a rear sandō (裏参道, ura-sandō) if it is a secondary point of entrance, especially to the rear; side sandō (脇参道, waki-sandō) are also sometimes found. The famous Omotesandō district in Tokyo, for example, takes its name from the nearby main access path to Meiji Shrine where an ura-sandō also used to exist.

Sand (surname)

Sand is a surname. Notable people with the surname include:

Boil

A boil, also called a furuncle, is a deep folliculitis, infection of the hair follicle. It is most commonly caused by infection by the bacterium Staphylococcus aureus, resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. Boils which are expanded are basically pus-filled nodules. Individual boils clustered together are called carbuncles. Most human infections are caused by coagulase-positive S. aureus strains, notable for the bacteria's ability to produce coagulase, an enzyme that can clot blood. Almost any organ system can be infected by S. aureus.

Signs and symptoms

Boils are bumpy, red, pus-filled lumps around a hair follicle that are tender, warm, and very painful. They range from pea-sized to golf ball-sized. A yellow or white point at the center of the lump can be seen when the boil is ready to drain or discharge pus. In a severe infection, an individual may experience fever, swollen lymph nodes, and fatigue. A recurring boil is called chronic furunculosis. Skin infections tend to be recurrent in many patients and often spread to other family members. Systemic factors that lower resistance commonly are detectable, including: diabetes, obesity, and hematologic disorders. Boils can be caused by other skin conditions that cause the person to scratch and damage the skin.

Boil (disambiguation)

A boil is a localized accumulation of pus in the skin, resulting from infection of the hair follicle.
