Hydrological Sensors

Hydrological sensors are used to monitor water level, quality and conditions in a broad range of applications, including surface water, ground water, rain water, and in rivers, oceans and reservoirs.

They are used to monitor:

Water infrastructure (dams, water treatment plants, pipelines, sewers, etc.)
Environmental conditions of rivers, aquifers, reservoirs and watersheds
Drawdown or recharge of ground water during underground construction
Dewatering performance at mine sites, TSFs and other critical infrastructure
Flood warning systems and stormwater network performance

Monitoring water level, quality and condition

Effective water resource management and flood prevention depend on accurate monitoring of the water cycle. Reliable data is essential to understand changes in water levels, flows and quality over time.

The safe operation of hydraulic infrastructure, such as dams, relies on continuous monitoring of reservoir and river conditions.

During underground construction, works are often carried out below the ground water table. Designing and constructing these engineered structures requires accurate information about ground water levels and behavior at all times. Monitoring is critical when artificially lowering the ground water level, which can have detrimental affects on surrounding infrastructure.

Hydrological sensors are also important at contaminated sites where soil and groundwater remediation is required, or the movement of plumes must be controlled.

The following hydrological monitoring sensors are commonly used:

Water level (non-contact – ultrasonic radar)
Water level (contact – VW, diver, 4-20mA, digital, float)
Bubblers
Velocity & flow (open channel, stream, pipe)
Rainfall (weighing, tipping bucket, optical, piezoelectric)
Soil moisture (volumetric water content)
Snow depth (for alpine hydrology).
Evaporation / evapotranspiration
Sunlight / intensity
Barometric pressure
Weather

Water quality parameters including:
- Temperature
- pH
- Electrical conductivity
- Turbidity
- Dissolved oxygen
- Nutrients (eg, nitrate, phosphate)
- Contaminants

Monitoring with hydrological sensors allows you to:

Understand the condition of water resources
Prepare for extreme rises in water levels and flooding
Maintain correct operation of hydraulic infrastructures
Ensure safe construction of underground works
Control contaminated sites and remediation projects
