Short summary
This study explores how to improve models predicting water flow in southern Vietnam's Saigon and Dongnai rivers, where data are scarce. By testing three different methods to adjust the river model using river water level and river discharge measurements, we found ways of better predicting river behavior. These findings can help manage water resources more effectively and aid in decision-making for flood protection and environmental conservation.
