Efficient operation of a water source is pivotal in harnessing water resources and mitigating flood-related damages. Precise forecasting ofinflow rates to dam reservoirs is crucial for effective reservoir control. As a result, extensive research at both international and domestic levelshas been conducted to develop and optimize flow forecasting models. This article presents a demonstration of runoff forecasting with rainfalldata using an established tank model. The model is implemented and visualized using MATLAB Simulink. To optimize and validate themodel, data from studies of the Thac Xang hydropower reservoir are utilized. The proposed flow prediction model has been adjusted toachieve a correlation coefficient of 74.0%. This model was used to predict the flow rate for the period from 1971 to 1976, achieving acorrelation coefficient of 70.0%. The model predicted a flow rate trend that closely matched the measured flow rate trend at the monitoringstations in this area. Although the correlation coefficient is not high in this case, the model can still be applied to predict flow and effectivelymanage and regulate the water resources at the Thac Xang hydroelectric reservoir in Vietnam.Vận hành hiệu quả nguồn nước có vai trò then chốt trong việc khaithác tài nguyên nước và giảm thiểu thiệt hại do lũ lụt.
