Setting Up the Observation Wells for Measuring the Water Level in the Field

The HOBO Water Level Logger is applied to measure the water level in the field. Each water level logger is installed in a observation well. As shown in the picture, the tube of observation well above ground is buried before tilling (planting) or harvesting and raised again after planting or tilling (harvesting). A JUNO handheld GPS device and a metal detector are used to locate the buried observation wells.
