Research Group on Groundwater
Background and Target
Global-scale environmental changes have recently caused the new problems
on the groundwater such as controlling the impounded water in the landslide
lakes resulted from slope failure or mudflow , the spreading radioactive
material by the accident in the Fukushima Daiichi nuclear power station
in March 2011.
They are complicatedly connected with the existing research objects such
as the regional groundwater flow, and the water flow in cracked bedrock.
The research group aims to resolve these problems through the activities
of the following working groups.
Working Group 1 on the groundwater in wide urban area
Working Group 2 on the groundwater in the cracked bedrock related to Dam,
Tunnel, Slope.
Working Group 3 on the groundwater in the bedrock of the repository for
geological disposal of Radioactive waste
Working Groupe 4 on the transfer of radioactive material on groundwater.
Reseach Group on Engineering Geomorphology
Background and Target
Landforms can be a resource of the valuable information with the practical
benefits for local communities, however, that requires the establishment
of the methods to clarify the causality between the existing landform and
its historical background or the formative mechanism, and to evaluate its
engineering characteristics, and to predict its future.
On the other hand, although the revitalization of rural economy by the
tourism industry has recently been attracting lots of attention, the value
of the cultural and historical heritages, that have been traditionally
cultivated in our country, cannot be evaluated unless we understand the
landforms where the heritages are located because they also have close
relationship to the landform.
The research group aims to establish such a method to provide the public
with the landform information as the public can easily understand the technical
implication of landform and as the public’s realization can be deep and
rich, and as the landform gives movement of emotion and practical benefit
to users.

Reseach Group on Environmental Geology
Background and Target
Natural disaster has recently been increasing its occurrence and extent.
The one of the important assignments of the Environmental Geology is to
protect the public from natural disaster and to maintain the environment
around the public through the studies to establish the social structure
and the techniques to maintain the infrastructure.
The conservation of the environment related to ground and soil draws increasing
attention and the public often consults the research group about the contamination
of soil or groundwater and so on. To resolve such issues is also one of
the assignments of the research group.
In addition, the research group’s assignments include wide area of issues
such as energy and water resources, life’s diversity, conservation of geo-ecological
system.
The research group aims to research the environmental geology that includes
above mentioned problems and return the results of research to JSEG’s member
and society
Research Group on Engineering Geology for Disaster Prevention
Background and Target
In Japan, various terrestrial changes such as earthquake, severe rainstorm,
and volcanic eruption occur year after year, and they often cause sediment
disasters such as landslide and slope failure. Predicting the occurrence
of such natural disaster and reducing the damage, and accelerating the
rehabilitation after the disaster crucially needs to utilize the geological
expert knowledge and experience.
The research group aims to find out a good deal of knowledge about the
geological disasters, such as earthquake and slope failure, by means of
applying the engineering geological investigations and the research methods
to them and to utilize the knowledge for prediction of the occurrence of
geological disaster, reduction of the damage, and for the activity of rehabilitation.

Research Group on Engineering Geology in Civil Engineering
Background and Target
‘Toward the Renovation of Engineering Geology in Civil Engineering’
In recent years, the amount of civil engineering construction has been
reducing due to the slumping Japanese economy. However, the engineering
geology is indispensable not only for civil engineering structures but
also for the utilization, conservation and management of our national land.
Engineering geology has been developed in response to the needs for the
construction of civil engineering structures. Hereafter, in addition to
such development, the engineering geology has to prepare new technologies
in response to the present-day issues such as economical construction,
the problem of aging infrastructures and national land devastation, natural
disasters, environmental problem, waste problem, energy problem, welfare
problem etc.
Furthermore, the systematization and international standardization of Japanese
engineering geological techniques is needed the adaptability for global
problems such as water crisis.
Then, our research group aims to renovate our engineering geological techniques
for utilizing them to the present-day and international problems.
Our research group makes the case studies on engineering geological problems
and the state-of-the-art technologies on civil engineering sites, and discusses
what new desirable techniques are, and how we should contribute. Finally
we work to make new systems and standards of the modern engineering geology
in civil engineering.
