Research progress on the tidal creek system is reviewed in terms of classification, morphological characteristics, and evolution processes of tidal creeks. It is suggested that the classification mode of tidal creeks proposed by Strahler based on the Hortons classification method is relatively reasonable. The total length of the tidal creek is positively correlated with the water catchment area, the tide range is positively correlated with the tidal creek density, and the influence of vegetation on the tidal creek density is inconclusive. Studies on the cross-sectional morphology of the tidal creek focus on the influence of the width-depth ratio, asymmetry, sediment, and vegetation on the cross-sectional morphology of the tidal creek. There are more qualitative results and fewer quantitative results regarding the dynamic mechanisms of tidal creek evolution. It is pointed out that, in future research, more attention should be paid to the complex flow structure in tidal creeks, the stability of side walls of tidal creeks, and the quantitative relationship between morphological characteristics of tidal creeks and their factors through physical model, numerical simulation, and remote sensing analysis techniques.
