Groningen Gas Field Induced Seismicity

Funded by the Dutch Ministry of Economic Affairs and Climate Policy (Project partner: Fugro)
We developed, using Discrete Element Modling code, PFC, a hydro-mechacnical coupled geomechanical model to simulate the induced seismicity and subsidence in the Groningen gas field, caused by over 60 years of gas production. The model was further extended to predict future seismicity scenarios in the field under fluid injection scenarios.

DECOVALEX 2019 - Hydro-Mechanical (HM) Modelling of Fault Reactivation

Funded by the Swedish Radiation Safety Authority (SSM)
We developed a coupled HM model to simulate fluid injection-induced fault slip experiments conducted at the Mont Terri Underground Research Laboratory (URL) in Switzerland.

DECOVALEX 2023 - Thermo-Mechanical (TM) Modelling of Rock Fracture Slip

Funded by the Swedish Radiation Safety Authority (SSM) and the US Department of Energy (USDOE) through Lawrence Berkeley National Laboratory (LBNL)
We developed a coupled TM model to simulate thermally induced rock fracture slip experiments performed by KICT. In addition, we led a task group focusing on coupled process modeling within the DECOVALEX 2023 project.

Funded by the Korea Radioactive Waste Agency (KORAD)
We are leading the coupled Thermal-Hydro-Mechanical (THM) modeling task in DECOVALEX 2027, investigating fluid flow and mechanical behavior in thermally induced slipping fractures.
ThermoQuake - Long-Term Thermal Evolution of Crystalline Rock Fracture System in a Spent Nuclear Fuel Disposal Site and Repository
Funded by the Swedish Radiation Safety Authority (SSM)
We developed a coupled TM-dynamic model using PFC3D to simulate both thermally induced and seismically induced rock fracturing in the Swedish spent nuclear fuel repository at the Forsmark site.

Wolsong LILW Disposal Site Safety and Performance Assessment
Funded by the Korea Radioactive Waste Agency (KORAD)
We carried out a comprehensive safety and performance assessment of the Wolsong Low- and Intermediate-Level Waste (LILW) disposal site, considering potential future climate impacts such as sea level rise, extreme precipitation, earthquakes, and surface erosion.
Site Descriptive Modelling for Korean Generic SNF Repository

Funded by the Korea Radioactive Waste Agency (KORAD)
We develop an integrated SDM workflow for Korea’s generic SNF disposal site, coupling rock-mechanics modeling with DFN characterization, groundwater flow and transport (hydrogeology), geochemical evolution (hydrogeochemistry), and radionuclide transport, providing traceable inputs for safety assessment.

Safety Case for Korean Generic SNF Repository
Funded by the Korea Radioactive Waste Agency (KORAD) 
We conduct a comprehensive review of the safety case for Korea’s generic SNF repository. The work examines site understanding, barrier performance, and THMC processes; evaluates baseline and disruptive scenarios; and assesses uncertainty treatment and traceability to ensure the documentation aligns with regulatory expectations.

TERALAND - Terrain Risk Assessment for Landslide through Detection and Simulation
Funded by the Federal Ministry for Economic Affairs and Energy (BMWE) on the basis of a decision by the German Bundestag 
TERALAND revolutionizes landslide risk assessment and mitigation by fusing advanced remote sensing with high-fidelity simulations. Built by a Türkiye Germany consortium, the platform delivers end-to-end capabilities from detection, scenario simulation, and quantitative risk evaluation to strengthen early warning, planning, and disaster preparedness.

TBM and EDZ
Funded by HeeSong Geotek and Hyundai Construction, this project develops a numerical framework to predict the EDZ in fractured rock during TBM excavation. The model quantifies damage intensity, fracture reactivation, and permeability shifts to support design optimization, risk control, and construction planning.
