The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid.Typically there are two surfaces (boundaries) which are at constant values of potential or hydraulic head (upstream and downstream ends), and the other surfaces are no-flow boundaries (i.e., impermeable; for example the bottom of the dam ...
The method of dam construction invented by Otto Intze was used in Germany at the end of the 19th and beginning of the 20th centuries. A dam built on the Intze Principle has the following features: it is a gravity dam with an almost triangular cross-section; the wall is made of rubble stone with a high proportion of mortar; it has a curved ...
In this case, hydrostatic relationships developed for uniform flow still apply. Examples of this include the backwater behind an in-stream structure (e.g. dam, sluice gate, weir, etc.), when there is a constriction in the channel, and when there is a minor change in channel slope.
Rolled-earth dams may also employ a watertight facing or core in the manner of a rock-fill dam. The frozen-core dam is a temporary earth dam occasionally used in high latitudes by circulating a coolant through pipes inside the dam to maintain a watertight region of permafrost within it. Tarbela Dam is a large dam on the Indus River in Pakistan ...
Hoover Dam from the air. Arch-gravity dams are dams that resist the thrust of water by their weight using the force of gravity and the arch action. [3]An arch-gravity dam incorporates the arch's curved design which is effective in supporting the water in narrow, rocky locations where the gorge's sides are of hard rock and the water is forced into a narrow channel.
Symbol used to represent in situ permeability tests in geotechnical drawings. In fluid mechanics, materials science and Earth sciences, the permeability of porous media (often, a rock or soil) is a measure of the ability for fluids (gas or liquid) to flow through the media; it is commonly symbolized as k.
A detention dam is a dam built to catch surface runoff and stream water flow to regulate the water flow in areas below the dam. [1] Detention dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. [2] Detention dams can also be constructed to replenish groundwater and trap sediment. [2]
