Abstract

 In Abashiri River, it is demonstrated that salt-water intrusion occurs when tidal level becomes more than the lake water level. It is expected that wind driven current enhances or suppresses. It is expected that wind driven current also enhances or suppresses salt-water intrusion. This study, thus, aims to investigate the influence of wind driven current on salt-water inturion in Abashiri River by following the previous study, which reveals that easterly wind more than 4 m/s enhances salt-water intrusion. An objectoriented environmental fluid dynamics model is applied to investigate the effect of wind driven current on salt-water intrusion. As a result, easterly wind is found to suppress salt-water intrusion, which may support that radiation stress plays a great role in salt-water intrusion compared to wind driven current.
