Abstract: Pump sampling can be an accurate method of measuring suspended sand concentrations. When the flow velocity through the pumping nozzle does not match the local stream velocity, however, an error is introduced. A simple ...

Abstract: The vortex tube is a device for extracting sediment from canals. A companion paper presented methods for assessing the trapping efficiency of vortex tubes. This present paper provides a flow analysis that is based on flow ...

Abstract: The vortex tube is a device for extracting sediment from canals that consists of a tube laid horizontally across the canal bed with an open slit along its top edge. Flow from near the canal bed is collected in the vortex ...
