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 Stevens-Schutzbach Method. Data that do […]
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 limited to critical flow (Fr […]
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. In this example, the hydraulic […]
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 flight. If the Froude Number […]
24. Sewer Amusement These data are from a flow monitor installed on one of three interceptors arriving at a wastewater treatment plant (WWTP). This unusual and entertaining pattern was created […]
