Research policy and content

The Hydraulics Laboratory conducts research on water and sediment dynamics in inland waters.Rivers are arteries that connect rivers from headwaters to the coast, but it is said that crossing structures such as dams and estuary weirs disrupt the continuous flow of water and sediment, affecting ecosystems and topography.Therefore, in our laboratory, we are conducting research on the following themes with the aim of coexistence between humans and nature.

  1. Research on sediment production processes in watersheds
  2. Research on sedimentation, water flow and eutrophication in dam reservoirs
  3. Research on sediment dynamics and riverbed changes in river channels
  4. Research on topography and sediment formation mechanism in estuaries

We are working on clarifying the aquatic environment by combining field observations, hydraulic experiments, and numerical simulations.We are also developing new measuring instruments necessary for observation.
