Current status and future prospects of the Horonobe International Project (HIP), 2; Task A: Solute transport experiment with model testing

Ozaki, Yusuke  

Task A of the Horonobe International Project (HIP) aims to investigate the characteristics of solute transport of the Koetoi Formation at 250 m stage of the Horonobe underground research laboratory (URL). The objective of this task is to develop a modeling approach of solute transport considering actual phenomena occurring in the rock based on in-situ tracer experiments along with the discussion on transferability of data and modeling approach from different geological environment. Phase 1 of task A is divided into four subtasks of planning of in situ experiments, laboratory experiments, field experiments, and modeling. These subtasks are tackled by participating organizations as collaborative research, and I present the current situation of each subtask and our cooperation.
