LEYVA-CRUZ, J. A. et al. Determining the gravitational effects on tide height on an estuary and theoretical comparisons. Rev. mex. fis. [online]. 2019, vol.65, n.5, pp.489-495.  Epub Apr 23, 2020. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.65.489.

Two identical homemade prototypes are used to monitoring the tide levels on two strategic points of the Serinhaém estuary. This monitoring was realized along a period close to the new moon phase. From the analysis of the experimental results, the average height of the tide is determined between each period of high-tide and low-tide. These estimations show discrepancies minors than half order of magnitude, compared to the theoretical predictions of the static and dynamic oceanic tide models. Also, the amplification effects of the tide in the estuary head can be quantified exhibiting a maximum gain of 1.33, which is observed in the new moon phase.
