Verification study on the hydrologic cycle analysis model and its reproducibility

- A case study at the Ono Basin in Fukui Prefecture -

Abstract

Based on the enactment of Basic Act on the Water Cycle, promoting social use of the hydrologic cycle analysis at the practical level is highly expected. Under this circumstance, National Institute for Land and Infrastructure Management, Ministry of Land, Infrastructure, Transport and Tourism published “Technical note on basin-wide water cycle analysis” as instructions and related materials of hydrologic cycle analysis procedure for local governments. As a complement to this publication, this report will describe the method of hydrologic cycle analysis modeling and verification approach of its reproducibility, based on the case study carried out at the Ono Basin in Fukui prefecture. Especially, this report will focus on reproducibility of the groundwater levels between monitored level and calculation result by using the analysis. In conclusion, this study will put the hydrologic cycle analysis to practice for conservation and sustainable use of groundwater.
