SUMMARY:Modelling Fractured Systems- Geo-Statistical and Stochastic Fracture Generation
DESCRIPTION:By applying a discrete model approach to study flow and solute transportprocesses in a fractured system, the effect of indiviual fractures canbe explicitely investigated. The critical step for a discrete fracturemodel is the generation of a ``representative'' fracture network thatcan accurately capture the behavior of a fractured aquifer system. Thestochastic fracture generation rely on the statistical distribution offracture geometries, such as orientation, density, aperture or length,however, not the spatial connectivity between fractures. In this talk,the geo-statistical fracture generator which accounting for bothfracture geometries and the spatial connectivity will be presented andits results will be compared with the one from the stochastic fracturegeneration.Based on the geostatistic approach, different realizations of the samedescriptions can be generated, hence, an overall behavior of thefracture-matrix system have to be investigated from many realizationswhich means high computational demand. Due to this, the streamlinemethod is an attractive alternative to overcome the computational cost.The streamline approach for solute transport in a fracture-matrix systemwill presented and the results will be discussed and compared with theresults obtained from solving a mass conservative transport equation.
