Establishing a 3D model of groundwater advection and diffusion at Fushimi ward in Kyoto basin

Kyoto city has various traditional cultures and industries. One of them is the production of Japanese sake, for which Fushimi Ward in Kyoto is famous. The purpose of our study is to maintain the groundwater resource that supports the life and culture of people in Fushimi ward. Firstly, we measured the groundwater level and came to understand the groundwater properties in this area. Next, we analyzed the 3D simulation of groundwater while using those data. Having arranged the bore data, we then constructed an accurate stratum model necessary for analyzing. We then analyzed the seepage flow in order to reproduce the groundwater flow. Finally, we assumed how contamination occurred in groundwater by using the result of the seepage flow analysis with maximum accuracy, and subsequently carried out the advection and diffusion analysis. For the purpose of groundwater conservation, we would like to use this simulation model as a general assessment to protect the resource and the environment of groundwater.EIT-JSCE Joint International Symposium on Geotechnical Infrastructure Asset Management 2011,EIT-JSC
