This study investigates the structures of flow field in the mouth of Kao-Ping River, southwest Taiwan. The data used in this study are collected from several cruises of field observations using research vessel OR3 and fishing boats. Instruments deployed include bmADCP, sbADCP, towADCP, Aquadopp, CTD, XR420 and Seacat37. Spatial and temporal variations of flow, sea level, temperature and salinity data are sampled. The collected data are analyzed through harmonic analysis, low-pass filter and FFT.
Results from previously study showed that cold water flowed eastward into the canyon during flood, and westward out of the canyon during ebb. This study shows that the canyon head is not the channel for bottom layer water to climb up into the shallow bank or the river (perhaps the bottom water climb up over shelf at the turning of the canyon 5 km offshore). The summaries are: (1)Water mass are moving around dominated by the oscillation M2 tidal current. There are 3 hours lag between sea level and flow. Maximum out canyon flow found at the peak of flood, while in canyon flow found at the low water. (2)The coastal surface water flows southeast during flood, and goes to northwest during ebb. (3)Tide current is the primary dynamic in the Kaoping River.During flood, lower temperature and higher salinity seawater is up river. During ebb, higher temperature and lower salinity is down the river. Amplitude of tidal current decreases with depth (likely due to bottom friction) at river mouth depth of 3 meters.
