A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils.
Culverts come in many sizes and shapes including round, elliptical, flat-bottomed, open-bottomed, pear-shaped, and box-like constructions. The culvert type and shape selection is based on a number of factors including requirements for hydraulic performance, limitations on upstream water surface elevation, and roadway embankment height.

A culvert pipe under a road is a common target for beaver damming because the constriction speeds up the current and may resemble a hole in a dam. With a little work, a beaver can quickly plug a culvert with mud and sticks, and turn the entire roadbed into a large dam.
In the more general case, channels with non-uniform non-circular cross-sectional area, such as the Tesla valve, the hydraulic diameter is defined as: [5] =, where V is the total wetted volume of the channel,
This season, Shesterkin has an 8-9-1 record in 18 games with a 3.05 goals-against average and .908 save percentage. For his career, he's compiled a 143-68-18 record with a 2.48 GAA and .920 save ...
These two types of flow are similar in many ways, but differ in one important aspect. Pipe flow does not have a free surface which is found in open-channel flow. Pipe flow, being confined within closed conduit, does not exert direct atmospheric pressure, but does exert hydraulic pressure on the conduit.
A key piece of evidence against Mr Hakamata were red-stained clothes found in a miso tank at his workplace. They were recovered a year and two months after the murders and the prosecution said ...
Invert level affects flow from drainage pipes. In civil engineering, the invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. [1]
