Abstract

Abstract

Based on the repeated short-term shipboard Acoustic Doppler Current Profiler (ADCP) surveys of three sections around the coastal area of Hongyanhe Nuclear Power Station, the L-curve method was used to separate tidal and residual current. The relationship between the movement of water masses and the direction of residual currents was analyzed and the characteristics of tidal currents were compared with literatures. Regression analysis of flow field verified that L-curve method for de-tiding under this situation was reasonable. The results suggested that: (1) The tidal current characteristics separated by L-curve method were in good agreement with the previous observations, and the semi-diurnal and diurnal tidal current components can be separated effectively, but all of data used in this paper were less than typical diurnal period. Therefore, the results of diurnal current and dynamic analysis of the flow field were still unreasonable. We need to use observations with longer time and more repetitions to correct the deficiency. (2) The residual currents flew to southward nearshore and northward offshore, which was consistent with colder saltier water intruding from south in deep water and warm fresh water run from north along the coastline. (3) The regression values derived from the L-curve method were highly correlated with the measured instantaneous velocity. The root mean square error (RMSE) was about 6 cm/s, and the relative error was about 10%. L-curve method can be extended to de-tide at any critical sections to obtain the important information such as coastal circulation variation and material transport fluxes to estimate the water exchange and resident time.
