“…However, the precipitation varies under climate change, because the ratio of rainfall and snow would increase. Furthermore, the variations of meteorological parameters, e.g., temperature and humidity, may cause the changes in evapotranspiration (Cong et al, 2009;Shimizu et al, 2015), as well as river runoff and groundwater discharge in the water budget. Thus, the uncertainty of percentage of evapotranspiration, river runoff, and groundwater discharge in the total water budget may exist.…”

Abstract. Fresh submarine groundwater discharge (SGD) is the key pathway of flux and nutrients for the groundwater from land to the ocean. SGD flux is a current issue of discussion and a means to clarify the coastal marine system under climate change. SGD flux accounts for about one-quarter of the river runoff in the Katakai alluvial fan in Uozu, Toyama, Japan, which is an ideal area to study SGD flux considering the need for a rapid response to climate change and the prior research on SGD there. In this paper, the monthly groundwater table's condition over 30 years is analyzed using monthly rainfall, snowfall, and the climate change index. Rainfall has been on an upward trend, but the snowfall has decreased over 40 years. Furthermore, the groundwater table at monitoring wells in the coastal area increased, as a result of the increased rainfall. However, the relationship between snowfall and groundwater is negative. As expected by Darcy's law, SGD flux was controlled by the hydraulic gradient of the coastal groundwater. The estimated historic SGD flux by groundwater table variation shows an upward trend of SGD. Considering the increase in precipitation and the groundwater table, SGD flux may increase under climate change.

We reviewed studies conducted in Japan that examined the relationship between forest condition and runoff, water movement in hillslopes, and stand transpiration. The effects of forest evapotranspiration and delayed runoff mechanisms by forest soil are reviewed in section II. We describe previous experimental results showing the role of preferential flow e.g., pipe flow and the contribution of Hortonian overland flow to subsurface water flow in hillslopes in section III. The transpiration in forest stands estimated with sap flux density measurements, which have spread rapidly in Japan, are presented in section IV. We suggest the future issues which should be solved in each section. Continuous and long-term datasets of runoff are required as the baseline reference for estimates of forest evapotranspiration and to investigate the effects of global warming on runoff processes section II. For hillslope processes, we recognize the investigation into impacts of increases in heavy rainfall events and longer intermittent dry periods between rainfall caused by the climate change as important subjects for further investigation section III. There is a lack of evaluation of transpiration in deciduous forests and comparisons of transpiration estimates with evapotranspiration obtained from other methods. Thus, we recommend studies to fill these gaps as well as applying sap flux density calibrations section IV
