Logs with a higher density than the density of water would sink. [2] Other logs would get caught in jams, sloughs, or floods, and become lodged in the riverbed. Such logs were often known as "sinkers" or "deadheads." Loggers attempted to reduce the number of logs which remained in the river in order to maximize profits, but some losses were ...
An example of ice cover reinforcement, where four layers of stacked wooden logs were frozen into the ice (in, [26] from a description provided in [16]). Ice crossings can be made to support higher loads if they are reinforced, and there are a number of ways this has been done in the past.
The brine-rich water remains liquid, and its increased density causes this water to sink, setting the stage for the creation of a "brinicle". Its outer edges begin accumulating a layer of ice as the surrounding water, cooled by this jet to below its freezing point, ices up in a tubular or finger shape and becomes self-sustaining.
Brine rejection is a process that occurs when salty water freezes. The salts do not fit in the crystal structure of water ice, so the salt is expelled. Since the oceans are salty, this process is important in nature. Salt rejected by the forming sea ice drains into the surrounding seawater, creating saltier, denser brine.
A "full deck" of logs awaiting the mill. A log pond is a small natural lake or reservoir used for storage of wooden logs in readiness for milling at a sawmill.Although some mill ponds served this purpose for water-powered sawmills, steam-powered sawmills used log ponds for transportation of logs near the mill; and did not require the elevation drop of watermill reservoirs.

("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 span the entirety of the water's surface from bank to bank. Log jams form when trees floating in the water become entangled with other trees floating in the water or become ...
One method of working atop muskeg is to place large logs on the ground, covered with a thick layer of clay or other stable material. This is commonly called a corduroy road . To increase the effectiveness of the corduroy, prevent erosion , [ 4 ] and allow removal of material with less disturbance to the muskeg, a geotextile fabric is sometimes ...
