However, the above two methods cannot obtain effective rainfall during heavy rain
Accurate rain gauges cannot be obtained using traditional barrel rain gauges because the rain gauge is too heavy and the barrel rain gauges are quickly filled and rainfall cannot be obtained

Embodiment Construction

[0046] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0047] Specifically, the present invention provides a method for measuring and calculating the atomized rainfall of flood discharge, comprising the following steps:

[0048] (M1) Select a typical rain collection area at the atomization site;

[0049] (M2) Excavate a 1m×1m pit on the underlying surface of the rain collection area according to the existing slope;

[0050] (M3) Make a device for measuring and calculating the atomized rainfall of flood discharge according to the slope;

[0051] (M4) Install a device for measuring and calculating the atomized rainfall of flood discharge in the tank;

[0052] (M5) for rainfall measurement.

[0053] The above-...

Abstract

The invention provides a method for measuring flood discharge atomization rainfall capacity, which belongs to hydrologic survey methods. The method consists of four steps that (M1) a typical rain collection area is selected at an atomization site; (M2) a 1m*1m groove is arranged in the rain collection area according to the existing slope; (M3) a device used for measuring flood discharge atomization rainfall capacity is arranged in a tank; and (M4) rainfall capacity measurement is carried out. The invention has the advantages that accurate rainfall capacity can be measured during a flood discharge atomization rainfall process.

Description

technical field [0001] The invention discloses a method for measuring and calculating the rainfall of atomized flood discharge, in particular a method for measuring and calculating the rainfall caused by atomization of flood discharge for high dams. Background technique [0002] Flood discharge from deflected high dams often causes atomized rainfall in the area below the dam. Due to the high power of flood discharge, the atomized rainfall is often extremely severe, reaching the level of heavy rainstorm or extra heavy rainstorm. There are two traditional ways to measure atomized rainfall: one is to use raindrop paper to obtain the number of raindrops, and the other is to obtain the density of raindrops through infrared rays penetrating the rainfall area. However, the above two methods cannot obtain effective rainfall during heavy rain. Accurate rain gauges cannot be obtained using traditional barrel rain gauges because the rain is so heavy that the barrel rain gauges are qu...
