Application of Excel in Single-line Integration Alignment

Application of Excel powerful drawing and function to make single-line graphics and stage-discharge curve fitting in hydrologic data processing has many advantages: reducing the arbitrary results from freehand drawing in integration alignment,decreasing the workload of data processing,improving the efficiency and precision,and the fit curve expressed in function facilitates computer processing.We take the observed discharge data of the Hebian station in 2009 as an example to illustrate the application of Excel in the single-line integration alignment.
