River habitats for animals and plants which are well adjusted to the environments can be categorized into various forms according to hydraulic characteristics such as current velocity and water depth, as well as to the kinds of riverbed materials such as gravels, sand and mud. In particular, freshwater fishes create many types of habitats according to the river's current velocity, water depth and riverbed materials. These days, a range of researches are being conducted at the inside and outside of the country to study the habitats of fishes, and numerous techniques are used to effectively classify such habitats. In Korea, Woo et al. (1998) proposed a critical flow necessary for habitats of fishes in determining the river maintenance flow. Lee et al. (2006) proposed a technique of calculating the flow amount necessary for fish inhabitation. Lee (2007) conducted research into restoring river ecosystems and riverine aesthetics in urban stream. Also, abroad, Fonstad and Marcus (2005), Handcock et al. (2006), and Marcus et al. (2003) conducted research to identify the inhabitation environments of animals and plants using satellite images' RGB band and infrared band. |
