 note = {The purpose of this study is to clarify hydraulic phenomena in the estuarine basins of ice-covered
rivers. Field observations were therefore conducted. As a result, it was found that reducing the time for
each measurement was important when conducting flow observations in estuarine basins. Similarities and
differences of phenomena in rivers when they were covered or not covered with ice were also clarified. Similar
phenomena indicate a correlation between the water-level fluctuation velocity and the total discharge, and
the two different relationships between the tidal and water levels that result from increases and decreases in
the former. Different phenomena indicate a great variety in flow direction depending on the tides when the
rivers were covered with ice, and the reduction of the freshwater flow velocity due to the friction resistance
of ice sheets during salinity intrusion.},
