Estimation of Net Flux of Water Mass and Tidal Prism at a Tidal Entrance through Bottom Tracking with ADCP

摘要

In this study,the bottom tracking observation in the tidal entrance within Mokpo coast is performed using ADCP in order to estimate net flux of water mass and tidal prism.First of all,observed rawdata was conducted coordinate rotation considering rotation of the cross-section in order to derive the predominant velocity component.And observed rawdata is converted into Sigma coordinate with normalization and blank zone data near the water surface and bottom is interpolated using von-Karman equation.Net flux of water mass is calculated quantitively from the interpolated data,calculated results show that these represent well characteristic of ebb superiority at Mokpo coast as well as change of net flux of water mass with tide.Also,by complementing the definition of tidal prism proposed in past studies,the definition of tidal prism including tidal condition was re-established.Based on the new definition,tidal prism at a tidal entrance using bottom tracking data with ADCP is estimated quantitively for the first time domestically.The results are compared with those for results of previous study,calculated results were in good agreement with previous studies.
