WebIn order to convert gage height (or "stage", usually expressed as feet) into streamflow (or "discharge", usually expressed as cubic feet per second), USGS hydrographers must establish a relationship between them. This stage-discharge relationship is called a rating curve. It’s developed by making frequent manual discrete discharge measurements at … WebA hydrologist often needs to know both the velocity and discharge of a stream at a particular location. By using the physical properties of the stream such as water depth, the channel shape, area, steepness and material along the streambed, along with formulas from engineering such as Manning’s equation, it is possible to calculate both of these quantities.
WebThe discharge ( Q) can be calculated by the following formula: Q = V ´ A where: Q is the Discharge in m3/s; V is the Average Flow Velocity in m/s; and A is the area in m2 of the … WebThe discharge ( Q) can be calculated by the following formula: Q = V ´ A where: Q is the Discharge in m3/s; V is the Average Flow Velocity in m/s; and A is the area in m2 of the Wetted Cross-section. If one wants to know the discharge in l/s instead of m 3/s, the formula to use is: Q = 1 000 ´ V ´ A where Q is the Discharge in l/s;

It is often expressed as cubic feet per second (ft 3 /sec). The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel. It is affected by weather, increasing during rainstorms ...

This set of information is eventually integrated by mid-section method to determine river discharge. This satisfies the equation Q = A * V. Succeeding paragraphs of this module elaborate ... extending respiteThe hydraulic radius is one of the properties of a channel that controls water discharge. It also determines how much work the channel can do, for example, in moving sediment. All else equal, a river with a larger hydraulic radius will have a higher flow velocity, and also a larger cross sectional area through which that faster water can travel. This means the greater the hydraulic radius, the larger volume of water the channel can carry. buck air sampler screens
