Probing Groundwater behavior-Ground flow and transport modeling


Published:2024-10-30  08:42

Technology Introduction
To describe the complex groundwater flow within rock masses, the Institute of Geology and Geophysics selects suitable analytical tools based on the characteristics of different geological materials, simulation scales, and objectives. Tools such as MODFLOW, DarcyTools, and FracMan are used for various analyses, including groundwater flow field simulations, particle transport modeling, tunnel inflow analysis, and grouting simulations.

Project Planning/Technology Application
Based on hydrogeological conceptual models and their characteristic parameters, a regional-scale steady-state flow field and transport simulation was completed (Figure 1). Following the configuration of disposal facilities and the locations of fracture intersections with these facilities, a transient inflow analysis model was developed (Figure 2). Additionally, based on the distribution of fracture spaces, a detailed analysis of fracture intersections with disposal facilities was carried out (Figure 3).
 
Future Arrangements
NARI develops and continuously improves analysis techniques for groundwater flow and transport, expanding their applications. In the future, to meet domestic government as well as industrial needs, NARI is actively endavoring to address those challenges related to assessing inflow potential in transportation tunnels, geothermal energy development, geological CO₂ sequestration, and final disposal of radioactive waste.
