To ensure accurate and prompt water resource forecasting, the following forecasting options must be implemented:

- The commonly used options in short-term water resource forecasting include:- The option of using correlation charts constructed according to the following methods: Rainfall-flow relationship; the relationship between the total water volume at the forecast point and the total discharge volume of the upstream reservoir; the relationship between the total water volume of the upstream station and the downstream station on the same river slope;- The option based on similar statistical methods;- The option of using mathematical models: Regression model; analysis and statistical modeling; concentrated parameter hydrological model; distributed parameter hydrological model; hydraulic model; reservoir operation model; tidal forecast model.- The short-term water resource forecasting and warning options used in the national hydrometeorological forecasting and warning system are specified by the National Hydrometeorological Center.- Individuals conducting forecasting and warning activities not belonging to the national hydrometeorological forecasting and warning system shall specify the use of the forecasting and warning options as appropriate.

Refer to the relevant regulations at Circular 40/2016/TT-BTNMT effective from February 10, 2017.
