  Dam - Biocrawler   (Site not responding. Last check: 2007-10-16)
Rock-fill dams are embankments of loose rock with either a watertight upstream face of concrete slabs or timber or a watertight core.
Earth dams, also called earthen and earth-fill dams, are constructed as a simple homogeneous embankment of well-compacted earth, sometimes with a watertight concrete or clay core or upstream face, or sometimes with a hydraulic fill to produce a watertight core.
A type of temporary earth dam occasionally used in high latitudes is the frozen-core dam, in which a coolant is circulated through pipes inside the dam to maintain a watertight region of permafrost within it.

 Dam - Encyclopedia, History, Geography and Biography
A diversionary dam is a structure designed to divert all or a portion of the flow of a river from its natural course.
The locations where timber dams are most economical to build are those where timber is plentiful, cement is costly or difficult to transport, and either a low head diversion dam is required or longevity is not an issue.
In a constant-angle dam, also known as a variable radius dam, this subtended angle is kept a constant and the variation in distance between the abutments at various levels are taken care of by varying the radii.

 Dry dam - Wikipedia, the free encyclopedia
A dry dam is a dam constructed for the purpose of flood control.
Dry dams typically contain no gates or turbines, and are intended to allow the channel to flow freely during normal conditions.
Development of dry dams was pioneered by the Miami Conservancy District which built five such dams on tributaries to the Great Miami River to prevent flooding of the Miami Valley and Dayton, Ohio.

 Britain.tv Wikipedia - Dams
Dams can be formed by human agency, natural causes, or by the intervention of wildlife such as beavers.
Dams which are formed by human agency are typically classified according to structure, intended purpose or height.
However, in order to prevent tensile stress at the upstream face and excessive compressive stress at the downstream face, the dam cross section is usually designed so that the resultant falls within the middle at all elevations of the cross section (the core).

 HYDROLOGIC EFFECTS OF CHINA’S UPPER MEKONG DAMS
Completion of Manwan, Dachaoshan and Jinghong dams will of course add to dry season discharge as water is released for power generation, but overall their effect will be negligible, as the Mekong Secretariat recognized in its report Mekong Mainstream Run-Of-River Hydropower (1994: 6-34).
He said that construction of the Xiaowan dam will not decrease the total amount of water reaching the countries in the lower reaches, for it is not a water-diverting project between different drainage systems.
The operation of the Manwan Dam appears to have considerable impacts on the water levels and discharges at this station during dry seasons from November to April.

DAM (Dry Absorbent Media) carpet cleaning is not dry (as in Webster’s definition of “dry"); it is moisture controlled.
Since DAM cleaning employs physical contact instead of hot water pressure, carpet stain resistant materials are not diluted or removed.
DRY chemical-free carpet cleaning is safe for all fibers, and excellent for natural fibers, such as wool, sisal, coir and cotton.

A second 82-metre high dam wall (the left-hand wall with gates and spillways that is behind and wraps around the old wall, on the right when the panorama opens) was proposed after the original dam was unable to withstand the flood of 1952.

It was proposed that a high dam be built on the Columbia River at the head of the upper Grand Coulee, a unique geological feature in the ancient riverbed of the Columbia, formed when the original channel was blocked by glaciers during one of the Ice Ages.
Excavation for the base of the dam, and construction of highway and railroad connections to the damsite and the necessary construction camp facilities was started in December 1933.

The extent of entrainment in Secret Ravine and Dry Creek is unknown, however, small diversions may have a significant impact on juvenile salmonids due to the small size of the water column.

The problem here was that during the dry season the pond behind the dam would dry up and any fish trapped there were doomed.
The dam however tended more to trap fish as the water would leach through the broken rock rather than be contained for the summer or flow over the dam.
The old dam was removed and, as suspected, was found to consist of only rock and sandy gravel.

 Historic power dam imperiled by MNR
The historical evidence is in the form of a small dam, a mill pond, race and flue, and a few scattered remnants of what once was a thriving mill and generator.
