Article Synopsis
- The Saigon River's hydrology is complex, affected by tidal cycles and low net discharge, posing risks for flooding and salt intrusion.
- A low-cost technique was developed for estimating river discharge every 10 minutes using a specialized rating curve, validated through ADCP campaigns and pressure sensors placed at key locations.
- The study reveals that rainfall has limited direct impact on water levels and discharge in this estuarine system, but indicates potential interactions between precipitation, groundwater, and the river network, proposing this method as a versatile tool for tidal river assessment.
A multi-technique approach is proposed to study sand dynamics in an engineered piedmont river. Only a few studies focused on such systems and innovative methodological protocols still need to be designed to better understand sand transport in piedmont rivers where bedload dynamics has been largely modified with nowadays a residual sand transport on a fixed gravel matrix. The proposed methodology is based on an analysis of bathymetry and turbidity measurements and on modelling, including the development of sediment rating curves and 2D numerical modelling, and using sediment budgeting for cross-validation.
