  abstract = {{T}he hydrological dynamics of the {S}aigon {R}iver is ruled by a complex combination of factors, which need to be disentangled to prevent and limit risks of flooding and salt intrusion. {I}n particular, the {S}aigon water discharge is highly influenced by tidal cycles with a relatively low net discharge. {T}his study proposes a low-cost technique to estimate river discharge at high frequency (every 10 min in this study). {I}t is based on a stage-fall-discharge ({SFD}) rating curve adapted from the general {M}anning {S}trickler law, and calibrated thanks to two {ADCP} campaigns. {T}wo pressure sensors were placed at different locations of the river in {S}eptember 2016: one at the centre of {H}o {C}hi {M}inh {C}ity and one in {P}hu {C}uong, 40 km upstream approximately. {T}he instantaneous water discharge data were used to evaluate the net residual discharge and to highlight seasonal and inter-annual trends. {B}oth water level and water discharge show a seasonal behaviour. {R}ainfall, including during the {U}sagi typhoon that hit the megalopolis in {N}ovember 2018, has no clear and direct impact on water level and water discharge due to the delta flat morphology and complex response between main channel and side channel network and ground water in this estuarine system under tidal influence. {H}owever, we found some evidences of interactions between precipitation, groundwater, the river network and possibly coastal waters. {T}his paper can be seen as a proof of concept to (1) present a low-cost discharge method that can be applied to other tidal rivers, and (2) demonstrate how the high-frequency discharge data obtained with this method can be used to evaluate discharge dynamics in tidal river systems.},
