Researchers typically employ statistical methods such as correlation analysis, regression analysis, and hydrological modeling to establish the relationship between flow (e.g., streamflow, river discharge) and precipitation. Correlation analysis evaluates the strength and direction of the linear relationship between precipitation and flow variables. Regression analysis models the dependence of flow on precipitation using mathematical equations, while hydrological models simulate the complex interactions between precipitation inputs and flow outputs, considering factors such as soil properties, land cover, and topography.
