Probabilistic

Everything we build we do on or in the natural ground. This has evolved over 10,000 years of geological history and varies greatly. Soil cannot be mapped accurately by the metre and therefore there is always a degree of uncertainty about what is in the subsurface. Using probabilistics, we can deal with this rationally.

Stochastic subsurface schematization (2016)

The subsurface is by nature highly variable. This makes it impractical to map the subsurface accurately. Geological Insight provides a systematics that responsibly incorporates variability into safety assessments of flood defences: stochastic subsurface schematization. The following two publications describe this systematics and its further development.

Geo-Impulse: reliable subsurface model (2014)

Within the Geo-Impulse project 'Reliable Subsurface Model', knowledge and tools are being developed to structurally deploy point information, geological knowledge, geophysical techniques, remote sensing and inverse modelling to arrive at a subsurface model with predictable reliability.

Dike Strength Analysis Module (2013)

DAM (Dike Strength Analysis Module) is a platform that can automatically perform strength calculations of large dike strains. DAM can calculate the failure probability of a dike without the need for soil testing. DAM was developed by Deltares with and for STOWA and a large number of water boards.
