System for measuring runoff sediment and interflow and building method thereof

Abstract

The invention relates to a system for measuring runoff sediment and interflow and a building method thereof. The system comprises a runoff sediment automatic measuring device, an interflow automatic measuring device and a recording device, wherein the runoff sediment automatic measuring device comprises building plates and a first measuring assembly; the building plates are vertically inserted into ground; the inserted part, under the ground, of each building plate is an underground plate section, and the reserved part, above the ground, of each building plate is a ground plate section; the ground plate sections are sequentially connected by connecting parts to form a runoff plot; the first measuring assembly comprises a sample outlet, a sediment measuring device and a runoff measuring device arranged sequentially from top to bottom; each building plate is connected with the sample outlet through a sample through pipe; the runoff water and sediment mixed sample in the runoff pot entersthe sediment measuring device through the sample outlet; the filtered sediment sample is measured by the sediment measuring device; the runoff measuring device is used for measuring the runoff watersample which flows through the sediment measuring device and then flows into the runoff measuring device; the recording device is used for recording the measuring results of the runoff sediment automatic measuring device and the interflow automatic measuring device.

Description

technical field [0001] The invention relates to the technical field of soil property measurement, in particular to a measurement system for runoff sediment and soil inflow and an assembly method thereof. Background technique [0002] The way to measure runoff and sediment indicators caused by water and soil loss is through the construction of runoff plots. The "Technical Regulations for Soil and Water Conservation Monitoring" (SL 277-2002) defines runoff plots as a main measure for monitoring water erosion in different types of areas, and is used to monitor the amount of water and soil loss. Widely used runoff plots usually include side ridges and the plots enclosed by them, collecting tanks, runoff and sediment storage equipment, and drainage systems. [0003] During the rainfall period, a part of the rainfall collects on the soil surface and flows sideways, also known as surface flow. It is a routinely measured runoff. Another part of the infiltration flow formed by rain...
