Abstract

The invention provides an earth surface runoff simulation system including a soil tank device, an artificial rainfall device, a rainwater recycling settling device and a terrain scanning device, wherein the soil tank device comprises a base, a jacking frame having one end hinged with the base, a soil tank arranged in the jacking frame, and a hydraulic jack connected between the base and the jacking frame; the soil tank is used for accommodating test soil and has one end with a water draining port; the artificial rainfall device is used for providing artificial rainfall to the test soil in the soil tank; the rainwater recycling settling device is used for receiving rainwater discharged from the water draining port; the terrain scanning device comprises a mobile vehicle and a scanner mounted on the mobile vehicle, and when the soil tank is in a horizontal state, the mobile vehicle can move along the soil tank, so as to utilize the scanner to scan a terrain of the test soil in the soil tank. The slope of the soil tank can be conveniently and steplessly regulated by the hydraulic jack, the test soil surface can be conveniently scanned through the scanner, the integral structure is simple, installation and operation are convenient, and simulation results are accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of hydrological simulation, and in particular designs a surface runoff simulation system for simulating the surface runoff caused by rainwater. Background technique [0002] Surface runoff mainly refers to the process of precipitation flowing on the soil surface, which is an important part of the water cycle. [0003] Runoff is one of the exogenous forces of landform formation and participates in the geochemical processes in the crust. It also affects the development of soil, the growth of plants, and the formation of lakes and swamps. Studying the occurrence process of surface runoff, its influencing factors, quantitative description and model prediction is of great significance for humans to make better use of natural precipitation, improve water use and protect the environment. [0004] Surface runoff research mainly uses field observation experiments and simulation devices for simulation research. Due ...
