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.

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,

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.
This is particularly useful for applying RADAR rainfall. ANUGA can model culverts and bridges with code from the open source Watershed Bounded Network Model (WBNM){Boyd, Rigby, VanDrie}, having a pipe, box and trapezoid routine. Development continues to create an arbitrary shape culvert solver that links to a 1D piped network model such as SWMM.
Darnold played an efficient, interception-free game in a 23-13 win over the Titans. Darnold lost a fumble but it didn't cost the Vikings in what would have been a bad loss for them against a ...
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]
