Abstract
Developing Watershed Environment Analysis System Using Arc Hydro Track: Education Author(s): Akiyuki Kawasaki, Satoru Sadohara Considering urban environmental problems requires investigating water resource availability, especially in relation to human activity. The aim of this research is to develop a watershed environment analysis system that analyzes relationships between observed water quality and socioeconomic and ecological data. This geodatabase covers upstream ecosystems in mountain and forest regions to middle and downstream areas primarily marked by human activity such as agricultural areas, and urban areas with artificial water supply systems (pipes, drainage canals, etc.). Attribute data was then included such as flow direction, water quantity and some quality data, junction types, as well as natural surface water flow in each watershed calculated with a DEM. The geodatabase was built for both the main water network in Kanagawa Prefecture (macro level) and for the local water network in Isehara City (micro level). In conclusion, environmental risk management in urban areas using the system and future works are described.
