This study is aimed at the development of management of surface water in the urban environment. In the civilization process of riverside, natural and humane environment has changed continually, and there are more frequent changes in flux and quantity of surface flow in civilized riverside than in natural riverside. Civilization concerned with the concentration of population and activity and expanding the range of urban area changed natural environment, and humane activity in urban area caused appearance of new hydrologic cycle system. This study defined the concept of urban environment and the role of river and investigated the change of natural environment caused by the civilization of urban area, the change of recharge from surface flow fluxing characteristics in urban river, and flux for suggesting the organization system of surface flow in urban river. To make the device which reasonably organize the surface water flow insurance in urban environment, this study systematically suggests the surface water flow management on flood-control, water-use and environmental aspect. To make the device which synthetically manage the surface water flow in urban river, this study suggests urban river synthetically management model which aims for harmony with nature which contains the concept of amenity, connecting with space, devotion to local for river development and preservation.

Mixed soil that is able to resist water is used as liner material. mixed soil that uses bentonite as its blend material is widely used for Liner layer in reclaimed land of waste. It is recognized that the Liner and durability of the material are good. However, enhanced engineering method of using the bentonite is not efficient enough to be used in basic test for the design and specifications. It is still difficult to design and implement something with bentonite economically. So it is required to suggest the standard of bentonite mixture ratio after testing its physical and engineering characteristics to use the result in civil engineering. This study shows reliable basic data of water permeability, which was obtained from a test of mixing sand, granitic soil of weathered rock and bentonite with different pressing strength and permeation water, and strength characteristics with different water blend and blend ratio. It suggests adequate blend ratio and pressing strength that meets the standard of design and construction.
