Speed Rail and Kee Lite are two common manufacturers of aluminum structural pipe fittings, a popular material in which to construct index-velocity meter mounts.

Diagram depicting stationing in midsection measurement where velocity measurements are acquired. Each station width is multiplied by the station depth and measured velocity to compute the discharge in each section. Section discharges are tabulated to compute a total discharge for the cross section.

In this photo, USGS scientists Megan Haserodt (Hydrologist) and Jenelle Wempner (Student Intern) install a double ring infiltrometer along a recreated floodplain of Underwood Creek, a tributary to the Milwaukee River and Lake Michigan in Milwaukee, Wisconsin. The work is part of a larger study of how overbank flows and shallow groundwater in floodplains are connected for
