OUR RESEARCH TOPICS

SUBSURFACE DAM

We have a research field in KIKAI island, Kagoshima prefecture in order to clarify the water and solute transport phenomena and to contribute an effective management of subsurface dam reservoir. Laboratory scale experiments related to salt water intrusion and solute transport in highly heterogeneous porous formations are also conducted.

OUR RESEARCH TOPICS

UNIQUE CONCRETE

The deficit of natural sand arises the need of alternative materials for replacement of natural sand. As for concrete structure, we explore the utilization of crushed stone powder which is locally available stone waste material. This study is expected to reduce the material cost and construction cost and to promote the SDGs. We are also developing some concrete materials involving porous concrete and fiber-reinforced concrete.

OUR RESEARCH TOPICS

ARTIFICIAL INTELLIGENCE

Seepage rate through, below, or around dams is an essential indicator of the health and condition of the dam. Any abrupt change in the amount of leakage may be a serious sign of deterioration of dam body. We aim to create an artificial intelligence capable of predicting seepage rate and giving an alert for dam management.
