Rising magma cooling underground which cuts vertically across exisiting rock Dikes and sills of Keweenawan time arose among the older Rove Formation which runs from Gunflint Lake east to Superior (our BWCA Region V) More resistant to erosion and glaciation than the surrounding rock, they delineate the long and narrow lakes which are the hallmark of this region
see dyke. Variant of dyke. another spelling of dyke. Bank, usually of earth, constructed to control or confine water. Dikes were purely defensive at first but later became a means to acquire polders (tracts of land reclaimed from a body of water through the construction of offshore dikes roughly parallel to the shoreline). After a dike is built, the polder is drained by pumping out the water. Where the land surface is above low-tide level, tide gates discharge water into the sea at low tide and automatically close to prevent reentry of seawater at high tide. To reclaim lands that are below low-tide level, the water must be pumped over the dikes. The most notable example of polder construction is the system adjacent to Holland's IJsselmeer (Zuider Zee) barrier dam. If The Netherlands were to lose the protection of its dikes, its most densely populated portion would be inundated by the sea and rivers
(1) (Engineering) An embankment to confine or control water, especially one built along the banks of a river to prevent overflow of lowlands; a levee (2) A low wall that can act as a barrier to prevent a spill from spreading (3) (Geology) A tabular body of igneous (formed by volcanic action) rock that cuts across the structure of adjacent rocks or cuts adjacent rocks
A tabular body of igneous rock that cuts across the structure of adjacent rocks or cuts massive rocks A massive wall or embankment built around a low-lying area to prevent flooding (Bates & Jackson 1984)
Bank of earth or stone used to form a barrier, frequently and confusingly interchanged with levee A dike restrains water within an area that normally is flooded See levee
Sometimes written as dyke; earth structure along sea or river in order to protect littoral lands from flooding by high water; dikes along rivers are sometimes called levees
Sometimes written as dyke; earth structure along a SEA or RIVER in order to protect LITTORAL lands from flooding by high water; dikes along RIVERS are sometimes called LEVEES
Anything constructed, assembled or installed to prevent flooding of land It may be an embankment, a wall, fill of sand, gravel, clay, silt or rocks pilings, pipe sluice, culvert, canal, ditch, drain, pump, gate or flood box
A low embankment, usually constructed to close up low areas of the reservoir rim and thus limit the extent of the reservoir Embankment for restraining a river or a stream Embankments which contain water within a given course Usually applied to dams built to protect land from flooding
An embankment used to confine or control water, especially one built along the banks of a river to prevent overflow of low lands or to deflect water away from a bank Also called a levee (4)
An embankment constructed of earth or other suitable materials to protect land against overflow from streams, lakes, or tidal influences or to protect flat land areas from diffused surface water
an embankment built to prevent overflow of water from a stream or other water body; an embankment built to retain water in a reservoir; a vertical or steeply inclined wall of igneous rock, which has been forced into a fissure in a molten condition
A discordant pluton that is substantially wider than it is thick Dikes are often steeply inclined or nearly vertical See also sill dilatancy The expansion of a rock's volume caused by stress and deformation
an earthen embankment constructed to retain floodwater; when used in conjunction with a bridge, it prevents stream erosion and localized scour and/or so directs the stream current such that debris does not accumulate; also known as dyke; see SPUR DIKE
