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 ...
In the early days, felled logs were transported using simple methods such as rivers to float tree trunks downstream to sawmills or paper mills. This practice, known as log driving or timber rafting, was the cheapest and most common. Some logs, due to high resin content, would sink and were known as deadheads.
There the logs were decked onto "rollways." In spring when snow thawed and water levels rose, the logs were rolled into the river, and the drive commenced. [6] To ensure that logs drifted freely along the river, men called "log drivers" or "river pigs" were needed to guide the logs. The drivers typically divided into two groups.
Sediment transport is the movement of solid particles (), typically due to a combination of gravity acting on the sediment, and the movement of the fluid in which the sediment is entrained.
("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 ...

Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies.
