The relationship between the accumulated precipitation(maximum water equivalent of snow)from the data of the AMEDAS observatory(ΣΡ)and the increase of unconfined groundwater level in snow melt season(ΔΗ) was considerably good. The successive tendency like as decreasing the accumulated precipitation for snow period do not seem to be admitted in the past 30-years.北海道大学大学院理学研究院自然史科学部門(地球物理学)2012-03-19jpndepartmental bulletin paperVoRhttps://doi.org/10.14943/gbhu.75.15http://hdl.handle.net/2115/4905210.14943/gbhu.75.150439-3503AN0008976X北海道大学地球物理学研究報告Geophysical bulletin of Hokkaido University751524https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/49052/1/75-P15-24.pdfapplication/pdf1.3 MB2012-03-19
