* * Final remark Different approaches to modeling, my personal philosophy is that they need to be mixed. Statistics is a very powerful geological modeling tool, but only when it is firmly supported by geological knowledge “No matter what prediction technique we apply to a variable we are unlikely to achieve an acceptable result unless we take geological effects into account.” (Houlding, 1994) * Garmoen Airport is situated on an Holocene ice-contact delta consisting of unconsolidated topset, foreset, and bottomset sedimentary layers.To assess risk for contaminant transport a subsurface flow model needed to be constructed. * New Jersey margin upto 30 m subbottom depth consists of Late Pleistocene shallow shelf deposits; paleo-fluvial deposits, barrier sands and shell and mud banks.

The subsurface has been formed over millions of years, and by the interaction of a host of sedimentary processes and time-varying boundary conditions like climate, sea level and tectonics. This course aims at exploring Geological Modeling techniques as: Learning tools to disentangle complex interactions of sedimentary systems and time-varying boundary conditions. Quantitative tools to create 3D geological models of the subsurface, including properties like grain size, porosity and permeability. A means to quantify uncertainties in the subsurface models. * Course outline 1 Lectures by Irina Overeem: Introduction and overview Deterministic and geometric mo
