Key Points

  • The aim is to assess driftwood inflow and effectiveness of water control measures in anti-flood ponds.
  • Conducted driftwood inflow experiments using a model of an anti-flood pond.
  • Evaluated driftwood inflow rates based on the number of driftwood pieces entering the pond.
  • Tested the effectiveness of water surface barriers under varying conditions of barrier number, transparency, and spacing.
  • Identified conditions that minimize driftwood inflow rate to the pond.
  • Measured trajectories of driftwood to pinpoint areas of concentrated inflow.

Abstract

本研究では流木が遊水地に流入する状況を想定して遊水地模型の越流堤部で横越流の発生下で流木投入実験を行った．まず遊水地に流入した流木の本数から流木流入率を評価した．次に水表面のみを遮蔽する水制を設置したケースについても実験を行い，遊水地への流木流入の抑制効果を調べた．水制の個数，水制の透過度，水制の設置間隔を系統的に変化させて遊水地への流木流入率が最も小さくなる条件を明らかにした．また越流堤部を領域分けし，通過した流木の軌跡を計測することで遊水地への流木の流入が集中する場所を評価することができた．
