Application of VIC hydrological model for simulating river flow of red river system to support water resource management
Abstract
This study aimed to apply the Variable Infiltration Capacity (VIC) hydrological model for simulating the daily river flow during the period of 2005-2014 for the Red River System, Vietnam. For this purpose, the VIC-3L hydrological model forced with satellite meteorological datasets was set up for the Red River Basin at the spatial scale of 0.1o × 0.1o (~11km × 11km). The daily monitored river flow data at four hydrological monitoring stations (Lao Cai, Yen Bai, Son Tay, and Ha Noi) along the Red River System for the period of 2005-2014 were used to evaluate the VIC-3L model performance. The study results showed that with the selection of appropriate soil parameters, it is possible to utilize the VIC-3L model to generate the daily river flow data for the Red River System. The VIC-3L model could capture the river flow dynamics of the Red River System. However, for the better model performance, future studies with respect to model calibration and validation should be carried out for more down-stream stations of the Red River System.
