29. Drifting Velocity Sensor This scattergraph displays data from a flow monitor with a drifting velocity sensor. Note that the reported flow velocity drifts over […]
28. Drifting Depth Sensor Most flow monitoring data can be described by the Manning Equation using either the Design Method, the Lanfear-Coll Method, or the […]
27. Undular Jump A hydraulic jump or other transcritical flow condition may reduce the accuracy of a flow monitor. However, this effect is not strictly […]
26. Hydraulic Jump This scattergraph is from a site that experiences a hydraulic jump. This condition occurs when flow transitions from supercritical to subcritical flow. […]
25. Iso-Froude Lines The Froude Number (Fr) is a dimensionless number used to describe flow conditions and is analogous to the Mach Number defining supersonic […]
