Background

We, Nippon Koei has provided enginnering services of river and dam designs since the company was found. This hydraulic model test facility is made for the experiment of designed structures which were the most difficult.
The experiment is still conducted even it have been almost replaced by computer simulations, that provides clarification of type and scale of designed stuctures and prediction of river-induced natural disasters.

Exposition of the Solution

This experimental facility can test:
  • River structures: bridge pier, diversion weir and side overflow weir of flood control reservoir
  • Sewerage systems: diversion weir, drop shaft and long inverted siphon
  • Dams: spillway and sabo dam

Achievements of Examples

We conducted many experience for experimental works from Japanese central and local governments.
