It relates to the change in the riffle-pool structures that were formed by developing alternate bars. In the present study, we discuss the change in the riffle-pool structure by using 2D numerical simulation and habitat evaluation method. By employing the frequency of the disturbance on the river-bed as a habitat suitability index, what the typical geomorphology with alternate bars helps the habitat condition to be maintained has been explained.}, pages = {1151--1156}, title = {河床攪乱頻度を指標とした生息場評価による瀬・淵構造の変質に関する考察}, volume = {46}, year = {2002} }
