This seminar is part of the Tuesday Seminar Series organized by the Center for Hydrogeology and Geothermics (CHYN) at the University of Neuchâtel. We are pleased to welcome Ana Paula Burgoa Tanaka, PhD student at the CHYN, who will speak about graph-based fracture network analysis and modeling.
Abstract
Fractures are typical rock discontinuities that enhance permeability and create flow anisotropies, playing a key role in groundwater circulation and karstification. This seminar will present how fracture networks can be represented and modeled to infer preferential fluid flow pathways in aquifers and reservoirs. After introducing traditional discrete fracture network modeling, the focus will shift to an alternative graph-based modeling approach. The graph-based fracture network analysis that integrates geometry, topology, kinematics, age relationships, and geomechanics was applied to identify the most important connections within the Tsanfleuron aquifer system in the Western Helvetic Alps.
