Validation at river

Validation contents

  • Confirm the river channel topography within the river area.
  • Confirm the topographic reproducibility of the beds along the ebb-water route and of the embankment shape.

Inspection result

  • Topographical reproducibility of the land portion goes toe-to-toe with near-infrared laser (TDOT PLUS).
  • More detailed water topography reproducibility compared to the advanced aerial laser sounding (ALB) .
  • The swift current of the river (Survey line No. 5), depth of water 0.69 m.
  • Curved scour depth section (Survey line No. 2, and 7), depth of water 1.94 m, 1.83 m.
  • Tributary Junction part (Survey line No. 8), depth of water 1.33 m.
  • Confirm the water bottom topography in various sections such as shallow waters, abysses, scouring places, branch joining places, etc.
