Applications of the SWAT model experimental forecasting flow on the Central Highlands rivers

Abstract

The use of hydrological models to forecast rainfall flows, especially in the dry season, is extremely urgent in the context of the Central Highlands being under pressure from climate change and unsustainable resource exploitation activities. This paper presents the application of the SWAT model to simulate flows on significant rivers in the Central Highlands. The paper uses data from hydrological stations representative of river basins in the Central Highlands. The 21-year data series from 2001 to 2022 is time-consistent with the rainfall series divided into 2 phases for model calibration and validation: a 12-year calibration phase (from 2002 to 2013) and a 9-year model validation phase (from 2014 to 2022). In addition, the paper conducts a test forecast for 2023 with source rainfall forecast data from the processed CFS, ECMWF, and MRI models. The evaluation results also show that the simulation quality of the model is relatively good.
