Abstract

 In Lake Komuke, an important flyway in Japan, salinity, water level, and seepage flow were observed in tidal flats and seasonal variation of dissolved organic matters were identified by fluorescence spectroscopy in order to clarify the relationship between water qualities and groundwater flow during spring and summer. At the offshore of the sandbar, the seasonality of fluorescence intensity of fulvic acid-like substances derived from soil in large lake means the seasonal variation of influence of river water and groundwater on water quality in the tidal flat. Groundwater in the tidal flat flew upward by an order of magnitude larger in spring than in summer. From the results of surface water in the tidal flat and the profiles of groundwater, upward flow likely reduces the increase of salinity in the groundwater.
