Hydro-environmental changes and their influence on the subsurface environment in the context of urban development.

摘要: The relationship between urban development and hydro-environmental change, particularly with regard to the subsurface environment is examined for three coastal cities affected by Asian monsoons (Tokyo Osaka in Japan, Bangkok Thailand). Major differences changes among these are closely related city size, structure, timing, stage extent of urbanization as well natural environment. work shows that has not hydro-environment same way it Tokyo Osaka. Three reasons difference account this, (1) Bangkok's abundant annual rainfall, (2) smallest ratio impervious pavement surface area, meaning water can more easily infiltrate underground., (3) degree urbanization. been heavily because underground yet reached deep subterranean areas. By researching cities, at different stages Tokyo, Bangkok, we plan quantitatively examine its influence on hydro-environments. This research will help limit damage developing experiencing failures but which expected confront problems future.
