specific Embodiment

[0023] Use the rainfall generating device of the present invention. The specification of the rain receiving device (width × length × height) is 1m × 2m × 0.5m, and the slope is 15°. The rectangular frame is made of metal, with 10mm thick glass or wooden boards inlaid around the rectangular metal frame, and wooden boards are inlaid in the metal frame at the bottom to form a rectangular slot. There is sandy loam in the rectangular tank, and the surface layer is planted with carnation grass. Soil moisture monitoring adopts 15 aqua-type soil moisture sensors made in the United States, which are monitored in three layers according to the cross shape. At the same time, the JH-AD1008 data collector made in the United States is selected. Set the rainfall intensity as 1mm / min, and the rainfall lasts for 10 minutes. The amount of rainfall entering the soil converted from soil moisture is 15kg, and the rainfall received by the rain receiving device is 20kg, so the runoff lost is about...

Abstract

An experimental facility of rain control and regulation consists of rain generating unit, rain receiving unit and monitoring unit. Its experimental method includes simulating different natural raining, generating redistribution of rain at vertical direction and horizontal direction on rain receiving unit because of different conditions simulated to ground in said unit, Knowing regulation action of different ground conditions to different raining by measuring ground surface water and water in soil.

Description

technical field [0001] The invention relates to a rainfall regulation experimental research device and an experimental method. The device can simulate natural rainwater rainfall and analyze the regulation effect of rainfall on soil. Background technique [0002] Water shortage has become a worldwide problem. Some people predict that the world is now fighting for oil, and in the future it will be fighting for water resources. All countries in the world are actively developing rainwater resource utilization technology while saving water. At present, the research on rainwater utilization can be divided into three categories: in-situ utilization, superimposed utilization and off-site utilization. Artificial simulation experiment research device and method is one of the main methods of rainwater utilization research, but there is no specific device and method. Contents of the invention [0003] The object of the present inven...
