Capability groups

From a water problem to a useful deliverable

Hydrology, hydraulics and flood modelling

Define flood behaviour, design flows and practical risk controls for catchments, sites and infrastructure corridors.

Typical sectors: Government, utilities, transport and development

Typical outputs

  • Hydrologic and hydraulic models
  • Flood maps and design flows
  • Flood-risk and peer-review reports

Methods may include: HEC-RAS, MIKE FLOOD, XP-RAFTS and appropriate 1D/2D modelling

Water security and resource planning

Understand supply reliability, drought exposure and the trade-offs between operating or investment options.

Typical sectors: Water utilities, councils, government and industry

Typical outputs

  • Yield and water-balance assessments
  • Scenario and option studies
  • Decision-support modelling

Methods may include: WATHNET, GoldSim, WEAP and system optimisation

Dam safety, reservoirs and hydropower

Support dam, reservoir and hydropower decisions with defensible hydrology, operations analysis and independent review.

Typical sectors: Utilities, asset owners, government and energy

Typical outputs

  • Dam-break and spillway studies
  • Reservoir-operation models
  • Feasibility and review reports

Methods may include: Hydrologic assessment, water balance and consequence-informed review

Drainage, scour and river engineering

Manage how water moves around roads, railways, pipelines, bridges and river assets through design and delivery.

Typical sectors: Transport, utilities and infrastructure delivery

Typical outputs

  • Drainage and scour designs
  • River-training inputs
  • Drawings, specifications and quantities

Methods may include: Catchment analysis, hydraulic design and sediment/morphological assessment

Mine water and environmental hydrology

Balance operational water needs with flood, diversion, storage, discharge and environmental constraints.

Typical sectors: Mining, resources and regulators

Typical outputs

  • Site water balances
  • Diversion and protection concepts
  • Environmental hydrology assessments

Methods may include: Scenario modelling, catchment assessment and operational planning

Independent review and expert advice

Give decision-makers a clear, independent view of technical quality, compliance, risk and next steps.

Typical sectors: Consultancies, councils, utilities, insurers and legal teams

Typical outputs

  • Peer-review and audit reports
  • Expert technical advice
  • Verification and due-diligence findings

Methods may include: Proportionate review against project criteria, standards and available evidence
