Case Studies#
End-to-end worked examples on realistic engineering problems, authored and validated by the Deltares team. Each case study demonstrates a complete probabilistic workflow: from problem definition and uncertainty characterisation to reliability results and interpretation.
These examples are more detailed than the tutorials. They use realistic model parameters, discuss engineering context, and show how to interpret results in a professional setting.
Geotechnical
Assess the probability of failure of a gravity-based retaining wall under uncertain soil parameters. Combines FORM analysis with Monte Carlo.
How to connect D-Stability to a probabilistic workflow using the GEOLIB Python library. Demonstrates the effect of load variability and correlated soil parameters.
Probabilistic settlement analysis by coupling D-Settlement to the probabilistic engine via a Python wrapper. Propagate soil parameter uncertainty through a full settlement model.
Connects a D-SheetPiling cantilever sheet pile model via the D-GEOLib Python library. Wraps the model as a limit state function and runs a FORM analysis with three stochastic soil and hydraulic parameters.
Builds a fragility curve for a D-SheetPiling wall as a function of a corrosion rate parameter. Integration of time-dependent reliability methods to show how failure probability evolves over the structure’s lifetime.
Slope stability reliability analysis driven by D-Stability. Uses the PTK Python wheel integration to evaluate the limit state function, enabling FORM and Monte Carlo runs directly against the D-Stability engine.
Flood Defences
Full assessment of a primary flood defence against two failure mechanisms: wave overtopping and internal erosion (piping). Shows how to combine failure probabilities into a system result aligned with the Dutch WBI assessment framework.
Compute a fragility curve for a hydraulic structure as a function of water level, accounting for uncertainty in structural resistance and load parameters.
