Résumé
This dataset is the result of a publication that explores calibration strategies and operational implications of 1D hydrodynamic modeling using the Mage code in the Saigon-Dongnai system in Vietnam. Three calibration approaches for the Mage model are evaluated, and coupling with the Modified Manning-Strickler (MMS) equation is explored for discharge estimation enhancement. Calibration efforts reveal distinct trends in friction coefficients along the river, with the introduction of indirectly measured discharge data significantly improving model performance, particularly for the Saigon River branch. This model output has been validated against independent measurements and demonstrates promising results, with the MMS coupling providing improved discharge estimates in the Saigon branch. The long time-series of water level and discharge (January 2016 to December 2022) provided in this dataset have practical implications for water resource management and decision-making in estuarine systems and is provided here in open-access for operational use.
