How to Calculate and Solve for Discharge Chezy’s Equation

WebThe relationship between the amount of water flowing at a given point in a river or stream (usually at gauging stations) and the corresponding stage is known as stage-discharge relationship or rating curve. The rating curve is usually plotted as discharge on x axis versus stage on y axis (Fig. 2.9 ). Figure 2.9. WebFeb 8, 2024 · The image above represents discharge Chezy's Equation. To compute for discharge, four essential parameters are needed and these parameters are Area (A), Chezy's Constant (C), Hydraulic Radius (R) and Slope (S). The formula for calculating discharge: Q = AC√(RS) Where; Q = Discharge A = Area C = Chezy's Constant R = Hydraulic Radius tourtrek hard case golf travel

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. tour trek t8. cart bag
