Rivers are not just for channeling precipitation (rain and snow) down to the mouths of rivers but also for the cycle of various substances. Landslides carried by the flow of a river have generated changes in landforms and created various natural environments through the organic substances that form in mountainous areas and forests. However, people have evolved using the sustenance of rivers since early times and have changed river basins according to their wishes while being occasionally faced by disasters such as floods and sediment disasters. In recent years catchphrases such as protection and conservation of the natural environment have become in vogue and the opinion that the approach to rivers by humans should be controlled as much as possible is growing stronger. At this laboratory we are researching the outflow phenomenon of water and landslides in river basins and how it can change the form of the land. We are also researching a method sophisticatedly balancing human society with the river environments by confirming the effect of such phenomenon on ecological systems and past river development transitions etc.
