| Research Abstract |
An ecohydraulic design method was developed for effective conservation of fish habitat in canals using the optimization theory. The suitability of the target canal section as a spawning site of Ayu was evaluated with habitat potential (HP) based on the habitat suitability index (HSI). A simulation-optimization method was presented that combined numerical simulation of open channel flow and the genetic algorithm, in order to place multiple blocks on the bed of the canal section under maximized HP. The developed method was applied to a hypothetical canal section, which showed the presented method can successfully produce optimal block configurations.
