Observation of river front at Tone River with X band radar network

This study analyzed the movement of river front at Tone River by using the echo data observed with X band radar network from January to June of 2010. Relationships between intensities and the propagation speeds of the front, and water level of Tone River, tide level and wind velocity and direction measured at Fishing Port of Choshi were analyzed. Front intensity tends to strengthen when tide level is descending. The alongshore propagation speed and the arrival point of front increase when the alongshore component of wind increases.
