This notch is also often referred to as C-notch, and is the most widely form of introduced notch, due to the repeatability of results obtained from notch specimens. Correlating U-Notch performance to V-Notch equivalent is challenging and is carried out on a case by case basis, there is no standardized correlation between performance values ...
Concrete check dams in Austria A steel check dam A common application of check dams is in bioswales, which are artificial drainage channels that are designed to remove silt and pollution from runoff. A check dam is a small, sometimes temporary, dam constructed across a swale , drainage ditch , or waterway to counteract erosion by reducing water ...
A polynomial weir is a weir that has a geometry defined by a polynomial equation of any order n. [11] In practice, most weirs are low-order polynomial weirs. The standard rectangular weir is, for example, a polynomial weir of order zero. The triangular (V-notch) and trapezoidal weirs are of order one. High-order polynomial weirs are providing ...
Notching is a metal-cutting process used on sheet-metal or thin bar-stock, sometimes on angle sections or tube. A shearing or punching process is used in a press, so as to cut vertically down and perpendicular to the surface, working from the edge of a work-piece.

This is because propagation of micro-cracks in the blade is approximately 10 times slower in maraging steel than in carbon-steel. It is a fencing urban myth that a maraging steel blade is designed to break flat; the breakage patterns are identical: both maraging and non-maraging blades break with the same degree of jaggedness.
In hydraulic engineering, a nappe is a sheet or curtain of water that flows over a weir or dam. The upper and lower water surface have well-defined characteristics that are created by the crest of a dam or weir. [1] Both structures have different features that characterize how a nappe might flow through or over impervious concrete structures. [2]
Stoplogs are designed to cut off or stop flow through a conduit. They are typically long rectangular timber beams or boards that are placed on top of each other and dropped into premade slots inside a weir, gate, or channel. Present day, the process of adding and removing stoplogs is not manual, but done with hydraulic stoplog lifters and ...
