EVALUATION METHOD OF SPRING WATER POTENTIAL DISTRIBUTION ON RIVER CHANNEL TOWARD HABITAT RESTORATION OF SPRING-DEPENDENT SPECIES

Abstract

Spring water always has a constant flow rate, so water temperature and water quality are stable. Therefore, it provides an important habitat for organisms living in such environments. It is important for the conservation of the habitat in the main river such spring water to capture the spring water potential (the inflow discharge of spring water per river length) as a matter of fact.

In this study, we combine existing hydrological and water quality survey methods in the Tsuya River basin inhabiting the spring water environment in light of the local situation, visualize the spatial distribution of the spring water potential in the longitudinal section of the river, By narrowing down the evaluation, we narrowed down the priority places of habitat restoration. We decided to propose a survey scheme of the spring water potential distribution obtained through these as a river technology supporting conservation ecology in the spring water river.
