“…The sensible and latent heat fluxes were estimated by the bulk method using the meteorological data observed. The snow surface temperature in the Ishikawa Prefecture of Japan is usually 0 ℃ (Takimoto et al, 2014;Maruyama et al, 2015); therefore, the sensible heat and latent heat flux can be calculated using the following equations:…”

Understanding snowmelt characteristics in forest areas is essential for the effective use of water resources because forests cover most of the mountainous areas in Japan. However, most previous studies investigating the snowmelt characteristics in open and forest areas have been conducted in March or later in the spring. In Japan, few studies have analyzed the energy balance of the snowmelt over an entire winter season, including the severe winter months. We selected Ishikawa Prefecture as the study area to clarify the characteristics of the energy balance for snowmelt in open and forest areas over the entire period of snow cover. The reduction of shortwave radiation by the forest was small during the severe winter months between December and February. The amount of longwave radiation was greater by approximately 25−85 MJ m -2 day -1 in the forest, which is significantly higher than that observed in the open area. We found that there are cases in which the energy available for snowmelt in the forest is larger than that in the open area, and that forests had no effect in terms of slowing the snowmelt during the severe winter months.

“…For instance, studies related to the Tedori River Basin include those by Noto et al [5,6], who attempted to estimate the amount of snow stored within the basin. Maruyama et al [7] and Fujihara et al [8] conducted comprehensive studies on the mechanisms of snow accumulation and snowmelt in this basin. Furthermore, concerning the Tedori River alluvial fan, Iwasaki et al [9] and Yoshioka et al [10,11] analyzed the characteristics of the groundwater within the alluvial fan, utilizing data on groundwater levels, water quality, stable isotopic ratios and so on.…”

The occurrence of high-concentration turbid water due to a large landslide in the upper reaches of the Tedori River Basin in Japan in May 2015 led to a rapid decline in the groundwater levels within the alluvial fan. However, factors other than turbid water, such as changes in precipitation patterns, can have a significant impact on groundwater levels but have not been thoroughly investigated. By analyzing the relationship between river water and groundwater levels, we found that by 2018, conditions had returned to those observed prior to the turbidity events. Regarding seepage, we found that approximately 24% of the Tedori River’s discharge contributed to seepage before the turbidity event. In contrast, during the post-turbidity years, seepage decreased between 2015 and 2017 and returned to the pre-turbidity levels by 2018. Furthermore, by constructing a hydrological model and examining the contributions of turbidity and precipitation, we found that in 2015, turbidity contributed to 76% of the groundwater level changes, whereas precipitation accounted for 24%. In contrast, in 2016, turbidity contributed to 67%, while precipitation contributed to 33%. In essence, the first year was characterized by a significant contribution from turbidity, while precipitation also played a significant role in groundwater level fluctuations in the second year.
