Development of Bio-hydrogeomorphology and Habitat Evaluation Model
The bio-hydrogeomorphology dynamics model was established and verified on the actural rivers.
The habitat evaluation model was development using the simulation results of water depth and river bed evolution.
The development of mid-long term riparian vegetation dynamics and habitat evolution model are on going with the consideration of climate change.
Development of the Advanced and Efficient River Channel Management Technology
With the spread of aerial laser survey data and UAV (unmanned aerial vehicle) survey data, we are developing technologies to improve the sophistication and efficiency of river channel management.
Extract tree information (height, diameter at breast height, density, and biomass) over a wide area of the river channel using ALB survey data and 3D scanners, and apply the extracted data to hydraulic analysis models
We use UAV to conduct field surveys, and machine learning to conduct dynamic habitat assessments is conducted based the field survey results of topography and riparian vegetation distribution.
Levee Breakage Process clarification & Failure Risk Evaluation of Revetment
Develop a risk assessment method that takes uncertainty into account for rivers with rapidly changing channels where it is difficult to predict hazardous locations.
A method for assessing the failure risk evaluation of the low water revetments is studied based on the concept of a stable river channel cross-section
Visualization Measurement of Flood Flow (Image Measurement and Analysis)
When measuring visualization of flood waters, the resolution of areas far from the point where the image is taken is low, making it impossible to measure.
This disadvantage can be mitigated through optical innovations to enable visualization and measurement of flood flows in a wider range of conditions.
Arrange the measurement methods and develop easy-to-use hardware and software, so that anyone can perform visualization and measurement of flood flows.
Flood Inundation Analysis(Damage to railroads and bridges)
Identifying conditions for damage to structures such as railroad and road embankments caused by flood flows,
based on inundation analysis (i.e. Nays2DFlood) and geographic information analysis
Predicting the occurrence of damage in advance, and developing a city-planning and countermeasures that can easily recover from a major flood event and implement.
