According to development and urbanization of country, environment and ecosystem were ignored during the past thirty years. Therefore canal, which had been developed by concrete, is remained as the space where life can not alive any longer. In this study, Environmental friendly canal construction method using porous loess block are investigated. Porous loess blocks are which is developing focused on both scenery and hydraulic safty. Canal using Porous loess blocks can take a vegetation's distribution and improvement of soil properties and hydraulic safty of bank. In this study, The examination of applied canal construction method using porous loess block that is considering vegetation's distribution and properties of material is done to present development of environmental friendly canal construction method.
