Debris flow

Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock rush down mountainsides, funnel into stream channels, entrain objects in their paths, and form thick, muddy deposits on valley floors. They generally have bulk densities comparable to those of rock avalanches and other types of landslides (roughly 2000 kilograms per cubic meter), but owing to widespread sediment liquefaction caused by high pore-fluid pressures, they can flow almost as fluidly as water. Debris flows descending steep channels commonly attain speeds that surpass 10 meters per second (more than 20 miles per hour), although some large flows can reach speeds that are much greater. Debris flows with volumes ranging up to about 100,000 cubic meters occur frequently in mountainous regions worldwide. The largest prehistoric flows have had volumes exceeding 1 billion cubic meters (i.e., 1 cubic kilometer). As a result of their high sediment concentrations and mobility, debris flows can be very destructive.

Basin is another term for sink or bowl.

Dock (maritime)

A dock (from Dutch dok) is either the area of water between or next to a human-made structure or group of structures involved in the handling of boats or ships, usually on or close to a shore, or the structures themselves. The exact meaning varies among different variants of the English language. "Dock" may also refer to a dockyard or shipyard where the loading, unloading, building, or repairing of ships occurs.

History

The earliest known docks were those discovered in Wadi al-Jarf, an ancient Egyptian harbor dating from 2500 BCE located on the Red Sea coast. Archaeologists also discovered anchors and storage jars near the site. A dock from Lothal in India dates from 2400 BCE and was located away from the main current to avoid deposition of silt. Modern oceanographers have observed that the Harappans must have possessed great knowledge relating to tides in order to build such a dock on the ever-shifting course of the Sabarmati, as well as exemplary hydrography and maritime engineering. This was the earliest known dock found in the world, equipped to berth and service ships. It is speculated that Lothal engineers studied tidal movements, and their effects on brick-built structures, since the walls are of kiln-burnt bricks. This knowledge also enabled them to select Lothal's location in the first place, as the Gulf of Khambhat has the highest tidal amplitude and ships can be sluiced through flow tides in the river estuary. The engineers built a trapezoidal structure, with north-south arms of average 21.8 metres (71.5 ft), and east-west arms of 37 metres (121 ft).

Basin (chanson de geste)

Basin is a chanson de geste about Charlemagne's childhood. While the Old French epic poem has been lost, the story has come down to us via a 13th-century Norse prose version in the Karlamagnús saga.

Plot

At the death of his father, an angel warns the young Charlemagne to take to the Ardennes and join up with the notorious thief Basin. During their adventures, Charlemagne learns of a plot to kill him and, in the end, the traitors are discovered, Charlemagne is crowned and Basin the thief is rewarded.

Historical sources

The traitors in the story (Rainfroi and Helpri) are most likely based on Chilperic and Ragenfrid who were defeated by Charles Martel in 717 CE. It is unknown if the author was acquainted with an 11th-century version of these events called Passio Agilolfi.

Influence

The names of the traitors in Basin were passed on to two other chansons de geste about Charlemagne's youth: Mainet and Berthe aus grans piés.

Debris

Debris or débris (UK: /ˈdɛbriː/ or /ˈdeɪbriː/; US: /dᵻˈbriː/) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, discarded, or as in geology, large rock fragments left by a melting glacier etc. Depending on context, debris can refer to a number of different things. The first apparent use of the French word in English is in a 1701 description of the army of Prince Rupert upon its retreat from a battle with the army of Oliver Cromwell, in England.

Disaster

In disaster scenarios, Tornado leave behind large pieces of houses and mass destruction overall. This debris also flies around the tornado itself when it's in progress. The tornado's winds capture debris it kicks up in it's wind orbit, and spins it inside it's vortex. The tornado's wind radius is larger than the funnel itself. In fact some studies suggest that in EF-5 tornadoes, the radius of the tornado could be classified as a new EF-6 tornado. Tsunamis and hurricanes also bring large amounts of debris. Such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. Earthquakes rock cities to rubble debris. Overall natural disasters can be very difficult to recover from. But in the end, we can always pull through what Mother Nature throws at us.

Debris (play)

Debris is an in-yer-face play by Dennis Kelly. It was first produced at the Latchmere Theatre (now Theatre 503) in London in 2003, before being transferred to Battersea Arts Centre the next year.

A one-act play where a brother and sister try to make sense of their dysfunctional childhood. The pair lie about their past creating new elaborate past stories, the central narrative is of the brother, Michael, who finds a baby who he names Debris trying to keep him a secret and alive from his alcoholic father confiding only in Michelle his sister who is fascinated with their mother's death and gives several contradicting stories of how she died.

In the first scene the brother describes coming home to see his father who has committed suicide by crucifixion. Kelly has said "I was brought up a Catholic, so, like every decent Catholic, as a child I fantasised about being crucified - it must have come from there"

Kelly original had problems getting Debris produced until approaching Theatre 503 "The play had been rejected by pretty much every other theatre around but 503 saw something in the play and decided to abandon common sense and produce it. For me it was one of the most important moments in my life"
