This study investigates the relation between the location of a habitat and the ecological
connections according to the habitat type in the riparian zone at the Nonsan Stream and
Yanghwa Stream. Stream habitat is classified into nine types for the aquatic insects and fish. For
vegetation and birds, habitat is classified into two types of medium-scale streams, including
both physical and chemical streams are analyzed accordingly. Nowadays, The fundamental
goal of the river environment restoration enterprise is the rehabilitation or the restoration of the
characteristic the river scenic or environment. For instance, The Channel habitats which has
physical nature environment such as flat, speedy rapids, or closed-channel wetland, pool are
constructed by artificial, Consequently, make them autogenesis smoothy eco-environment.
However, the river environment are controlled not only physical environment, but it also need
reasonable the quality of the water to compose smoothly. Finally, understanding what
influence are effecting on physical habitat environment which are made by natural factors to
water quality are very important factor for the river environment restoration enterprise.
Therefore, In this research, we are targeting to a basin to investigate the environment of the
physical channel habitat and evaluate the changing of the water quality. This results will be a
important characteristic that can judge the physical habitat and reciprocality connected to the
water quality or adequacy of restoration technology. Therefore in this study, as a step to
quantify functions and values of habitats and definite factors to perform habitat, we selected a
representative stream of sand-stream, gravel-stream to classify habitat characteristics and
quantified the physical, chemical, biological characteristics.
