ZHANG Wen, LIU Bingjun, CHEN Xiaohong, et al. Correlations between Salinity and Tidal Process in Modaomen Waterway of the Pearl River Estuary[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2013,52(6):11-16.DOI:
The Pearl River Estuary region is densely covered with rivers. Affected by runoff
tide and other natural factors and human activities
the salinity change process during salt water intrusion period is extremely complex. With the data of salinity from Guangchang Station and tidal range from Sanzao Station
the period features of salinity change and the correlation between tides and salinity change in Modaomen waterway were studied using wavelet analysis. The results show significant correlation between salinity change and tides in the cycle of 15 days. Phase difference is about 60°~90°
that means salinity changes ahead of tidal process about 2.5~3.75 days.
