Bridges between multiple-point geostatistics and texture synthesis : Review and guidelines for future research

Mariethoz, Gregoire ; Lefebvre, S

In: Computers & Geosciences, 2014, vol. 66, p. 66-80

Multiple-Point Simulations (MPS) is a family of geostatistical tools that has received a lot of attention in recent years for the characterization of spatial phenomena in geosciences. It relies on the definition of training images to represent a given type of spatial variability, or texture. We show that the algorithmic tools used are similar in many ways to techniques developed in computer...

A pseudo genetic model of coarse braided-river deposits

Pirot, Guillaume ; Straubhaar, J ; Renard, Philippe

In: Water Resources Research, 2015, vol. 51, no. 12, p. 9595-9611

A new method is proposed to produce three-dimensional facies models of braided-river aquifers based on analog data. The algorithm consists of two steps. The first step involves building the main geological units. The production of the principal inner structures of the aquifer is achieved by stacking Multiple-Point-Statistics simulations of successive topographies, thus mimicking the major...

Influence of conceptual model uncertainty on contaminant transport forecasting in braided river aquifers

Pirot, Guillaume ; Renard, Philippe ; Huber, E ; Straubhaar, J ; Huggenberger, P

In: Journal of Hydrology, 2015, vol. 531, p. 124-141

Hydrogeologist are commonly confronted to field data scarcity. An interesting way to compensate this data paucity, is to use analog data. Then the questions of prediction accuracy and uncertainty assessment when using analog data shall be raised. These questions are investigated in the current paper in the case of contaminant transport forecasting in braided river aquifers. In using analog data...
