“…Using numerical model experiments, Buschman et al (2010) showed that there is a significant decrease in tidal wave amplitude in the junction. Xiao et al (2021) confirm the results using field observation data that shows a significant tidal deformation in the tidal junction.…”

“…The tidal wave dynamics in estuaries have been studied in a range of topography settings, from single channel estuaries (Cai et al, 2018;Savenije et al, 2008) to branching estuarine systems (Buschman et al, 2010;Danial et al, 2019;Xiao et al, 2021). It was found that the tidal wave dynamics in estuaries are controlled by interaction tides and river runoff and affected by the topography setting.…”

“…Moreover, in a tidal junction, the division of discharge and tidal convergence may strongly influence the sediment division (Xiao et al, 2021) and affect the morphodynamics of the channel (Iwantoro et al, 2020).…”

“…The evolution of tidal waves is affected more by shallow water friction concerning bottom topography changes (Bilskie, et al, 2019;Khadami et al, 2020;MacMahan et al, 2014;Xiao et al, 2021). Using analytical approaches, the relation between friction and convergence channel in the tidaldominated estuary was examined by Savenije et al (2008).…”

Observations of water elevation in the short and small tidal junctions of the Ota River, Japan, showed an increase in tidal nonlinearity at the apex of the junction. To quantitatively estimate the increase in nonlinearity, the barotropic hydrodynamic model was applied in an idealized junction domain, inspired by the Ota River Estuary junction. Even though the model was simplified, it successfully reproduced the increase in nonlinearity at the junction apex. A sensitivity analysis of tidal nonlinearity to the width of the upstream channel at the junction was performed by varying the upstream channel width from the same width as the branch channel width to three times the branch channel width. The relationship between the upstream channel width at the apex and tidal nonlinearity was not linear. Tidal nonlinearity was maximized when the apex width was twice the branch channel width. The convergence of the tides in the small width junction induced an increase of some positions of quarter-diurnal tidal constituent that raised the tidal nonlinearity. In the case of a wider channel, the flushing from river runoff dampen the tidal constituents, making it decrease tidal nonlinearity
