Roca Remolinos
Roca Remolinos (lit. ''"Eddies Rock"'') is a submarine hill in Chacao Channel, Chile, notorious for being a major hazard for traffic along the channel. With its highest point at 20 m below sea level, Roca Remolinos does not break the surface during ordinary low tides, but its top can occasionally be seen during extremely low tides. It is located at the narrowest part of the channel, about 700 m from the nearest shore (the southern one). Its northern slope reaches 16° while its southern one reaches 14°. The rock composition varies: four different horizontal layers have been identified, all of which are made of combinations of sand and silt cemented by Iron(III) oxide, ferric oxide.Syngros, K.; Dobry, R.; Leventis, G.E.

Canal De Chacao 0007
Canals or artificial waterways are waterways or river engineering, engineered channel (geography), channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport watercraft, vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and lock (water transport), locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharge (hydrology), discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
