A NOVEL APPROACH TO MODELLING OF FLOW IN FRACTURED POROUS MEDIUM

Popis výsledku v původním jazyce

There are many problems of groundwater flow in a disrupted rock massifs that should be modelled using numerical models. It can be done via ?standard approaches'' such as increase of the permeability of the porous medium to accout the fracture system (ordouble-porosity models), or discrete stochastic fracture network models. Both of these approaches appear to have their constraints and limitations, which make them unsuitable for the large-scale long-time hydrogeological calculations. In the article, a new approach to the modelling of groudwater flow in fractured porous medium, which combines the above-mentioned models, is described. This article presents the mathematical formulation and demonstration of numerical results obtained by this new approach.The approach considers three substantial types of objects within a structure of modelled massif important for the groudwater flow - small stochastic fractures, large deterministic fractures, and lines of intersection of the large fracture
