To understand the characteristics and seasonal changes in flowing artesian wells in the Kurobe River alluvial fan (KRAF), the discharge, water quality, and isotope ratio of 23 flowing wells were observed for 18 months from March 2011. This paper newly reports the monthly discharge and water quality of these flowing wells. Variation in water flow at 10-minute intervals is also presented. All wells exhibited the same seasonal changes, and no spatial difference in water quality was found. Analysis of isotope ratios indicated that three wells located on the left bank of the KRAF were recharged from difference sources than the other wells that were recharged by the Kurobe River. Comparison with previous water quality measurements taken 10 to 20 years ago showed that the water quality had not changed. However, further research is needed to clarify long-term trends of the flowing water discharges.

为了了解黑部河冲积扇（KRAF）自流井的特征和季节变化，从2011年3月开始，对23口自流井进行了18个月的流量、水质和同位素比值观测。本文最新报告了月流量以及这些流动井的水质。还显示了水流以 10 分钟为间隔的变化。所有井都表现出相同的季节变化，没有发现水质的空间差异。同位素比分析表明，位于 KRAF 左岸的三口井的补给来源与其他由黑部河补给的井不同。与10至20年前的水质测量结果相比，水质没有变化。然而，需要进一步研究来阐明流水排放的长期趋势。
