  • AN ATTEMPT TO IMPROVE HABITAT EVALUATION METHOD FOR AQUATIC LIVES IN UPSTREAM RIVER REACHES

抄録

To improve a habitat evaluation method known as PHABSIM, we discussed the conventional preference curves that express ‘aquatic lives’ inclinations to specific physical properties of fluvial environment. and proposed a new parameter named ‘weight exponent’ for the preference curves reflecting degree of ‘each parameters’ influence on aquatic. Then we estimated the flow field of a study site in an upstream river reaches by an existing numerical model to apply the conventional model and the model proposed with the weight exponent.<BR>As results, we confirmed the superiority of the weighted PHABSIM model to evaluate the habitat suitableness, especially in the region of high population density. We think, a directivity for improvement of the PHABSIM model was presented.
