Different tests are more suited to certain aquifer types, i.e. Each type of aquifer test puts a different stress on the aquifer system and the resulting effects are observed and used to estimate hydraulic properties. Subsurface characteristics can be determined though various aquifer tests.Īn aquifer test is a controlled field test performed on one or more monitoring wells. How do Drawdown Measurements Help Determine Aquifer Hydraulic Properties? Check out our technical bulletin “ Best Practice Low Flow Methods for Highest Quality Samples” for more details. Levelogger Data is Adjusted by Inputing 101D Water Level DrawDown Meter Measurements in the Levelogger Software Data WizardĪpplication Notes: Both 101D Water Level DrawDown Meters and 3001 Leveloggers can also be used to aid low flow sampling (monitor drawdown and help regulate pumping rates) – providing more information for a complete aquifer characterization (aquifer chemistry). These calculations done automatically in the Levelogger Software Data Wizard, instead of another spreadsheet program, saves you time.

Manual measurements should be taken when the Levelogger is deployed, periodically during the recording period, and at the end of the monitoring period.Īfter you have downloaded the data from the Levelogger, you can use the depth to water measurements to convert Levelogger pressure readings to depth to water readings or elevation measurements to meet your specific application or model requirements. Using these two instruments together ensures accurate readings and saves you time when dealing with post data processing.Īs a QC check, you can use 101D Water Level DrawDown Meter depth to water measurements to verify the Levelogger is reading correctly. Note: for ease of use when lowering and raising from greater depths, the Solinst 101 Power Winder can be added to a 101D reel.
