Large woody debris, grains, and the shape of the bed of the stream are the three main providers of flow resistance, and are thus, a major influence on the shape of the stream channel. [1] Some stream channels have less LWD than they would naturally because of removal by watershed managers for flood control and aesthetic reasons. [2]
The term applies to a large stream or a small river. The word is used in Scotland and England (especially North East England ) and in parts of Ulster , Kansas , Australia and New Zealand . Etymology

The word sotāpanna literally means "one who entered ( āpanna ) the stream ( sota ); stream-enterer", after a metaphor which calls the noble eightfold path a stream which leads to ...

Handtub A historical fire engine pumped by hand with the water supply held in a tub or cistern on the wagon, the water supply delivered by a bucket brigade .
A Bronze Age fire-set pit. Fire-setting is a method of traditional mining used most commonly from prehistoric times up to the Middle Ages. Fires were set against a rock face to heat the stone, which was then doused with liquid, causing the stone to fracture by thermal shock. Rapid heating causes thermal shock by itself—without subsequent ...
A log jam is a naturally occurring phenomenon characterized by a dense accumulation of tree trunks and pieces of large wood across a vast section of a river, stream, or lake. ("Large wood " is commonly defined to be pieces of wood more than 10 cm (4 in) in diameter and more than 1 m (3 ft 3 in) long.) [ 1 ] Log jams in rivers and streams often ...
Humans have had several effects on the flood pulse. Through ecosystem alterations such as dams, debris removal, channelization, levees, navigation, irrigation, contamination, logging, fire suppression, species introduction, and agricultural runoff, humans have contributed to the destruction of wetlands and the extinction of species.
In economics and economic sociology, embeddedness refers to the degree to which economic activity is constrained by non-economic institutions. The term was created by economic historian Karl Polanyi as part of his substantivist approach. Polanyi argued that in non-market societies there are no pure economic institutions to which formal economic ...
