Abstract:

The accuracy of storage capacity calculation in the rivers and gullies depends on the selection of calculation method. Based on the comparative analysis of a variety of commonly used computational formulas in storage capacity calculation, the existing "pseudo-platform body formula" is modified, and the accuracy and application scope of these formulas are analyzed. The results show that the improved "pseudo-platform body formula" is feasible in calculating the volumes of all types of deposition bodies with trapezoid cross-section and the calculation error is small. The research results provide a reliable scientific basis for accurate and reasonable calculation of reservoir storage capacity.
