Uncertainty Management

Uncertainty is inherent to geosciences because the subsurface must be interpreted from incomplete and indirect data, so different valid explanations can exist at the same time. ITASCA helps clients address this reality by identifying, assessing, quantifying, and managing uncertainty throughout every stage of hydrogeological assessment and modeling:

• Rigorous data QA/QC to ensure fundamental data reliability.

• Development of system understanding through features–events–processes (FEP) analysis and alternative conceptual scenarios.

• Structured risk analysis to identify and prioritise key uncertainties.

• Manual and automated uncertainty simulations using the PEST suite to explore parameter and structural variability.

• Qualitative and quantitative consequence assessments that translate uncertainty into clear, decision‑relevant insights.

• Statistical interpretation, evaluation of uncertainty and uncertainty structure.
