Abstract

An artificial rainfall runoff and soil water motion simulation experimental system comprises a rainer, a runoff and soil water forming device, a water drainage device and a runoff volume measuring device. The rainer comprises a water supply device and a raindrop forming device; the water supply device adjusts water outlet strength by an adjusting valve and a flow meter; the raindrop forming device is a group of pipes with holes; the runoff and soil water forming device is a vertical container with a soil layer; the group of pipes with holes is arranged on the top of the vertical container and can be adjusted in a lifting manner; and the container comprises an inner wall on the inner layer and an outer wall on the outer layer, the inner wall consists of a water permeable steel wire gauze, the outer wall is made of a transparent material, the inner wall and the outer wall are connected with each other by a water impermeable layering steel plate, the water drainage device is arranged below the soil layer, a water leading pipe which is connected with the runoff volume measuring device is arranged outside the container, and the runoff volume measuring device performs data processing and operation by a computer. The artificial rainfall runoff and soil water motion simulation experimental system is convenient to carry, high in experimental efficiency, accurate and fast in operation and high in adaptability.

Description

technical field [0001] The invention relates to the fields of hydrology and soil-related professional experimental equipment, specifically, a simulation experiment system related to rainfall formation, runoff production and soil water movement, in particular to an artificial rainfall runoff soil water movement simulation experiment system. Background technique [0002] The water cycle is the link connecting the earth system "geosphere-biosphere-atmosphere". Due to the complexity and uncertainty of the influence of global climate change on precipitation, runoff and regional water circulation system, as well as the uncertainty of the structure and model parameters of the water circulation system caused by the impact of high-intensity human activities and changes in the underlying surface of the basin, the changing environment Uncertainty quantification research of distributed water cycle simulation in lower regions has become a major scientific issue in earth system science, a...
