Although the effective rainfall method has been widely used for analyzing groundwater level fluctuation in landslide sites, few previous studies have applied the method to snow-cover area throughout a year. This study estimated snowmelt by a simple and easy way, and analyzed groundwater level fluctuation in a landslide site in snow-cover area throughout a year using the effective meltwater and/or rainwater (MR). The results suggested that the groundwater level can be reproduced using the effective MR, and that incorporating the effect of evapotranspiration can improve the accuracy.
