specific Embodiment

[0061] (1) Basic conditions

[0062] There are two stations (hydrological stations) on the upper and lower reaches of a river basin in the plateau mountainous area, and the actual measured annual runoff of the upper station is Y 1 for the short series m 1 = 15, the measured annual runoff X of the downstream station is a long series n=53, and the measured annual runoff series of the upstream station and the downstream station are synchronized, and the unmeasured annual runoff series of the upstream station m2=38, see Table 1.

[0063] (2) Establish Y 1 Contemporaneous relationship with X

[0064] See formula ① for the simple correlation equation;

[0065] Calculation formula y 2 =0.0606X+93.535;

[0066] Where: y 2 ——The annual runoff of the upstream station (design station) interpolated and extended;

[0067] X——The annual runoff of the downstream station (referring station).

[0068] The 38-year runoff y of the upstream station is interpolated and extended according t...

Abstract

The invention discloses a processing method for accurately interpolating and extending the hydrological characteristics of a design station, and aims to provide a processing method for the hydrological characteristics of a design station closer to the real value. It includes the following steps: (1) simple linear correlation analysis; (2) complete linear correlation analysis; (3) partial value calculation; and (4) physical numerical calculation of complete linear correlation. The invention is applicable to the processing of hydrological characteristics of design stations in the technical field of hydrology and water resources.

Description

technical field [0001] The invention relates to the technical field of hydrology and water resources, and relates to a processing method for accurately interpolating and extending the hydrological characteristic value of a design station. Background technique [0002] In engineering design of water conservancy and hydropower, highways, railways, water delivery channels, etc., it is usually necessary to combine the short series Y of the measured physical values ​​of the hydrological characteristic values ​​of the design station 1 The interpolation is extended to a long series of physical values ​​Y. The general method is to select a reference station with hydrological characteristics of physical origin in the vicinity of the design station, and the measured physical value series X is longer, including the 1 Corresponding to the measured physical values, establish a simple linear correlation between Y and X, and interpolate and extend the missing physical values ​​y of the des...
