Related to Open-channel flow

Hydraulic jumpA hydraulic jump is an abrupt increase in the depth of a fast-moving liquid stream in an open channel, which is accompanied by a decrease in speed. The jump appears as a wavy or turbulent region between the high-speed upstream flow and the slower downstream flow. A common example is the circular jump formed when a tap runs into a kitchen sink. Hydraulic jumps occur below dam spillways and in rivers.

Hydraulic dropA hydraulic drop is a type of local phenomena found in open channel flow. It is a rapid change in the depth of flow from a high stage to a low stage that results in a steep depression in the water surface. It is often caused by an abrupt change in the channel slope. Another type of local phenomena found in an open channel flow is the hydraulic jump.

HydraulicsHydraulics (from Ancient Greek (húdōr)'water' and (aulós)'pipe') is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. Rooted in fluid mechanics, hydraulics is used to govern the use of energy via pressurized liquids. It has been part of human history since ancient times. Hydraulic topics range through some parts of science and most engineering modules.

Reach (geography)A reach is a segment of a stream or arm of the sea, usually suggesting a straight, level, uninterrupted stretch. It is traditionally defined by the capabilities of sailing boats, as a stretch of a watercourse which, because it is straightish, can be sailed in one "reach" (that is, without tacking).

Pipe flowIn fluid mechanics, pipe flow is a type of fluid flow within a closed conduit, such as a pipe, duct or tube. It is also called as Internal flow. The other type of flow within a conduit is open channel 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.

LiquidState of matter The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids.

Channel (geography)In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While channel typically refers to a natural formation, the cognate term canal denotes a similar artificial structure. Channels are important for the functionality of ports and other bodies of water used for navigability for shipping.

Free surfaceIn physics, a free surface is the surface of a fluid that is subject to zero parallel shear stress, such as the interface between two homogeneous fluids. An example of two such homogeneous fluids would be a body of water (liquid) and the air in the Earth's atmosphere (gas mixture). Unlike liquids, gases cannot form a free surface on their own. Fluidized/liquified solids, including slurries, granular materials, and powders may form a free surface.
