Reduces flood damage in the event of heavy rains: Toward social installation of the
Urban Flood Prediction System

2

By developing a sediment runoff prediction method with a focus on the behavior of fine-grained soil from theupper to lower reaches of a river, the NILIM contributes to the development of effective facility installment
plans against widespread damage due to sediment flooding/inundation.
Verification of reproducibility of the prediction method• Cases have occurred where the fine-grained soil that was produced
upstream accumulates from the upper to lower reaches of a river,causing widespread sediment flooding/inundation• A sediment runoff calculation method that can track the behavior offine grained soil is required• The reproducibility of the method for the Northern Kyushu Heavy
Rain was verified, and its adaptability was confirmed.

Development of an experiment facility that can reproduce
a variety of sediment movements• Development of an experiment facility that can reproduce thecomplicated process from the start of a debris flow to sediment
runoff and flooding<Overview of the facility>
A gradient adjustable

By developing a system to distribute flood prediction information 40 to 50 minutes prior to a flood,
we contribute to the appropriate evacuation and unerring response to floods.
Social experiment with the urban flood prediction system• An urban flood prediction calculation model was developed fromthe reality of the target area, such as the sewage network.
• Prediction and observation data, such as XRAIN, are obtained, andflood prediction information is delivered 40 to 50 minutes prior toa flood.

• A social experiment was conducted in the Kanda and Shakujii Riverbasins in Tokyo (March 2019)• With an eye toward the delivery and use of information during the2020 Tokyo Olympic and Paralympic Games, the NILIM continues
research via social experiments.

and people’s lives to ensure proper functioning in the event of a disaster.
• Based on the inspection results, measures that should be implemented immediately were compiled and implemented by thegovernment as the Three-year Emergency Plan for Disaster Prevention, Disaster Mitigation, and National Resilience in December
2018.

Long-term functioning of infrastructure! Realization of efficient and effective inspections
and repairs5

By developing technology to obtain maintenance and management data on port facilities via UAV and an
AI-based inspection-assessment system, we contribute to the realization of more efficient and effective
maintenance and management.
Development of the inspection-assessment system

Development of remote image transmission technology• We developed an AI-based system that could obtain highly accurate
image and location information via UAV for a prompt and accurate
assessment of deformations in facilities.

• Development of a system that smoothly transmits images in real time
while minimizing the effects, such as radio attenuation and shielding,in a port environment.

Total management of sewer pipelines• The deterioration of members for road bridges varies widely and sodoes the deterioration of repaired/reinforced members.

• Inspections of pipelines and steps to take in the event of an abnormal
situation were made obligatory.
• There are no specific standards for selecting an inspection or survey
method.
• If a technical judgment cannot be made, it is difficult to implement
inspections in an efficient manner.

Realization of safer road crossings by introducing a two-stage crossing facility

In an effort to prevent pedestrian accidents while crossing a road, we contribute to the introduction of
two-stage crossing facilities by making a technical standard proposal, including traffic conditions to which
two-stage crossing facilities can be applied and desirable geometric structures.
Making an examination of introducing a two-stage crossing facility
to the field site
• Through an on-site experiment, we examine the structure of a safe two-stage
crossing facility from the perspectives of both pedestrians and vehicles andthe road shapes for the sections ahead and behind traffic islands.
• Based on the waiting time of pedestrians and that of vehicles, which wereobtained through traffic simulations, we examine and identify the optimal
traffic conditions for the introduction of the two-stage crossing facility.

By promoting the examination of the size of port facilities that can meet the needs of larger-scale cruise ships
and research on the spatial formation of a port, we contribute to the realization of a tourism-oriented country
and regional revitalization that are associated with cruise ships’ port calls.
Response to larger-scale cruise ships

Analysis of economic effects of cruise ships’ port calls• An environment that can accept larger-scale cruise ships needs to be
developed.

• We estimate economic effects in a quantitative and accurate manner
while considering consumption differences by the nationalities ofpassengers and the number of ports of call.

• Examination of the size of facilities around water to meet the needsof large cruise ships with high operability

Evaluate reflection of results inpolicies and secondary effects, andreflect these in future R&D issues

Outside experts evaluate research activities as a whole at the NILIM, as well as environment improvement initiatives that support
the research activities, and the NILIM strives to improve its operation based on these results.

Research Departments and Administrative Departments cooperate and work on developing
young personnel systematically by combining Off-JT and OJT effectively. The NILIM holds internalpresentation meetings for young researchers who have little presentation experience and a study
group by young personnel aimed at enhancing development.
“Experience and Know-how Transmission Lectures” are held in order to make use ofaccumulation of research, experience, and know-how of predecessors for improving the skills ofeach personnel member.

Internal presentation meetingfor young researchers

We conduct compliance activities according to the promotion plan for the current fiscal year while giving due consideration to themonitoring results and advisory opinions of the Compliance Advisory Committee (External Expert Committee).

We make simple and timely introductions of
the activities and research achievements of the
NILIM. We normally send it out twice a month.
