Connected Water Systems

Surface Water ↔ Groundwater

Understanding risk across connected water systems.

Connected surface-water and groundwater system

Why the links matter

Actions and pressures in one part of the water system can create consequences elsewhere. Surface water and groundwater cannot be treated independently.

Illustrative pathways; responses depend on local conditions. Research themes are not automatically current projects.

01

Groundwater Abstraction

Abstraction → groundwater decline → possible subsidence → higher flood exposure.

02

Rainfall Deficit

Rainfall deficit → low flows and reduced recharge → groundwater drought.

03

Contamination

Source → groundwater plume ↔ river–aquifer exchange → receptor exposure.

04

Urbanisation

Impervious cover → more runoff and less infiltration → altered recharge.

Water Quality & Contamination Risk

Contaminants, transport and receptor risk across both water systems.

This is shared research, not a third laboratory. Water quality is a property of a water system, not a system on its own.

CharacteriseIdentifyUnderstandEvaluateConnectAssess

Baseline characterisation

Establish what is present, where, and under what conditions.

Parameter and contaminant selection

Choose measures that answer a question the data can support.

Fate and transport

How contaminants move through surface water and groundwater.

Standards, guidelines and thresholds

Compare observations against published criteria, with uncertainty.

Receptor exposure and risk

Connect concentrations to people, ecosystems and uses.

Data, Monitoring & Digital Systems

Measurements, data checks and shared maps for both laboratories.

This function serves the research laboratories. It is not a separate software unit and does not develop commercial products.

We use machine learning only when it helps us understand the water system. It is a method, not the brand.
