Abstract

Hydraulic habitat analysis of Benthic Macroinvertebrates was performed at Gapyeong stream. Among the kinds of the Benthic Macroinvertebrates, the most representative ones are the Ecdyonurus kibunensis from the clingers, Paraleptophlebia cocorata from the swimmers, Chironomidae spp from the burrowers, Psilotreta kisoensis iwata from the sprawlers. They showed different habitat types by the hydraulic conditions such as flow velocity, depth and particle size of riverbed materials. Habitat conditions of swimmers were determined mainly by the flow velocity rather than flow depth or riverbed materials. Burrowers prefer sand and silt, and inhabited at the riverbed. Sprawlers prefer cobble or boulder and inhabited for velocity of 0.05~0.15 m/s. Clingers prefer pebble or cobble and inhabited for velocity of 0.06~0.15 m/s. Although the habitats of each groups are different by the hydraulic properties, they were found to be different mainly by the water velocity.
