  2. Drainage equation - Wikipedia

    en.wikipedia.org/wiki/Drainage_equation

    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.

  3. Culvert - Wikipedia

    en.wikipedia.org/wiki/Culvert

    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.

  4. Flow device - Wikipedia

    en.wikipedia.org/wiki/Flow_device

    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.

    en.wikipedia.org/wiki/Hydraulic_diameter

    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,

  7. Pipe flow - Wikipedia

    en.wikipedia.org/wiki/Pipe_flow

    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.

  9. Invert level - Wikipedia

    en.wikipedia.org/wiki/Invert_level

    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]
