• TITLE: Habitat Evaluation on Scour Hole Downflow Low Drop Structure Types Using Large-Scale Experiment

  AUTHORS: Joongu Kang, Changsung Kim, Sanghwa Jung, Hongkoo Yeo

  KEYWORDS: Natural Low Drop Structure; Scour; River2D; Fish Habitat; Habitat Suitability Index

  JOURNAL NAME: Engineering, Vol.4 No.9, September 28, 2012

  ABSTRACT: This study sought to review whether large-scale experimentation can apply to actual rivers concerning the effect of topographical change by scour in the downstream area of natural-type low drop structures on the fish habitat. The large-scale applicability experiment performed in this study installed low drop structures as the study object within the experiment channel and precisely surveyed topography in the downstream area of drop structures along with the hydraulic amount including water level and flow velocity under certain flow conditions. Based on topographical data acquired through the survey after the experiment ended, this study reviewed the change of suitability index and difference of weighted usable area by performing 2D habitat simulation. Ultimately, through the habitat simulation results in cases of considering and not considering scour in the downstream area of drop structures, this study analyzed the effects of topographical change in actual rivers on the habitat.
