A 4" aluminum I-beam is used allow an ADVM to be raised and lowered on a stainless steel sled.

Temporary mount for installation of a horizontal ADVM under ice.  A large flange serves as a load bearing base plate with 2" pipe and pipe fittings being used to suspend the ADVM below.

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.

Did you know the USGS has been studying groundwater since we were founded? USGS first measured the groundwater level at the well in this photo in 1918, over one hundred years ago! How often water levels are measured at a site in the USGS groundwater monitoring networks varies, depending on the scientific purpose of the measurement.
