Groundwater Level Monitoring

Groundwater level monitoring is a critical aspect of geotechnical engineering, hydrology, and environmental science. It involves the measurement and observation of the elevation or depth of the water table or potentiometric surface (in the case of confined aquifers) within the subsurface strata. Regular monitoring of groundwater levels helps in understanding groundwater behaviour, detecting changes, and managing resources effectively to ensure adequate engineering design for our clients projects.

AETG Methods of Groundwater Monitoring

Groundwater monitoring is typically performed using wells installed at strategic locations. The types of wells used depend on the specific monitoring objectives.

Observation Wells: Observation wells are installed specifically to monitor groundwater levels. They are not used for water extraction but instead for monitoring purposes only. These wells are typically shallow or deep, depending on the aquifer being monitored. The well casing is often perforated at the depth where the groundwater is expected to be present.

Piezometers: A piezometer is a specialised type of well that measures the hydraulic pressure or water pressure at a specific depth. Piezometers are typically used to monitor groundwater pressure, and they are essential for understanding groundwater flow, especially in confined aquifers.

Monitoring Boreholes: Boreholes are drilled into the ground to assess the vertical profile of groundwater levels at different depths. These boreholes are typically fitted with instruments like piezometers and are useful for gathering detailed data on groundwater levels at multiple depths in deep aquifers.

How AETG Can Help Your Needs

Groundwater level monitoring is a critical practice for sustainable water management, environmental protection, and geotechnical applications. By continuously tracking changes in groundwater levels, engineers and hydrologists can ensure the safe design of structures, manage water resources efficiently, and protect ecosystems that depend on groundwater. Advancements in monitoring technologies have greatly improved our ability to measure and manage groundwater fluctuations, providing invaluable data for decision-making in water and environmental management.
