- Abstract:
- Recent field observations show that the water table in an unconfined coastal aquifer fluctuates at the frequency of spring-neap tidal cycles (1/14.78 d-1). These low-frequency fluctuations (SNTWF) propagate much further inland than semi-diurnal and diurnal tidal oscillations, and thus can affect significantly groundwater flow and contaminant transport in coastal aquifers. The cause of the SNTWF is not readily apparent since spring-neap tides are bichromatic signals (containing only two frequencies, 1/12 h-1 and 1/12.42 h-1 for semi-diurnal solar and lunar tides, respectively). We have proposed two theories to explain this phenomenon. This project aims to verify these theories and corresponding analytical solutions using field experiments. The research outcome will help to quantify the SNTWF, an important coastal phenomenon that has been mostly ignored so far.
