Stream discharge vs velocity
Web14 Jan 2024 · Discharge values on the y-axis were derived by measuring the velocity of water in the stream channel at a set of points in a cross-sectional transect of the stream at several sampling times. The velocity (measured … WebThe velocity–area method for the determination of discharge in open channels consists of measurements of stream velocity, depth of flow and distance across the channel between observation verticals. The velocity is measured at one or more points in each vertical by current meter and an average velocity determined in each vertical.

WebThe stream function is defined for incompressible (divergence-free) flows in two dimensions – as well as in three dimensions with axisymmetry.The flow velocity components can be expressed as the derivatives of the scalar stream function. The stream function can be used to plot streamlines, which represent the trajectories of particles in a steady flow.. The two …
WebThe discharge at any given point in a river can be calculated as the product of the width (in ft or m) times the average depth (in ft or m) times average velocity (in ft/s or m/s). The vast majority of rivers are known to exhibit considerable variability in flow over time because inputs from the watershed, in the form of rain events, snowmelt, groundwater seepage, … Web2 Sep 2024 · Discharge measures streamflow at a given time and location and specifically is a measure of the volume of water passing a particular point in a given period of time. It is …
