Movable earth surface runoff observer

Abstract

The invention relates to a transportable surface runoff observation installment, which is suitable to observe the surface runoff under each kind of field condition. The installment is mainly composed by the runoff collecting device, the runoff sample gathering installment, the runoff quantity recognizer, the data measurement system, rainproof guarantees shielding five parts. Using the equipment can carry on the immediate determinant under each kind of area, the different land utilization way, the different management measure, the different slope, the slope length surface runoff. Compares with the traditional runoff plot observation, the invention has transportable, directly carries on the observation, the high sample gathering accuracy under the natural condition of local growth runoff, the construction cost low, the use factor high, the application scope observation to the unit time runoff intensity merit and so on; compared with the existing transportable runoff observation installment, it has the merit of satisfying the open country great current capacity runoff observation, the simple installment and operation, the electronic record, the high observation accuracy, the few breakdown and so on. The installment installs easy to operate, the real result, the lower construction cost, is suitable for to promote.

Description

technical field [0001] The invention belongs to the technical field of agricultural production. It is a mobile surface runoff observation device, which is suitable for the observation of surface runoff under various field conditions. technical background [0002] Soil erosion is one of the major disasters in the world. It destroys land resources, causes productivity decline and siltation; consumes limited water resources, causes disasters such as drought and flood, causes deterioration of ecological environment, and seriously threatens human survival and development. issues of general concern. The problem of soil erosion exists to varying degrees in both developing and developed countries, and it tends to continue to deteriorate. According to the estimates of the Food and Agriculture Organization of the United Nations, the area of ​​land where water and soil erosion occurs in the world is as high as 25 million square kilometers, accounting for 16.7% of the total land area,...

AI Technical Summary

Problems solved by technology

It can be widely used in the monitoring of various non-pressure, low head, and small flow water flows such as runoff areas on slopes, mid-soil flow, subsurface flow in underground fissures, and base flow in small watersheds; the main problem is that the recording paper needs to be replaced regularly. It can only be used for small-flow runoff observations. The maximum observed runoff per minute is only 3kg. It is reported that the runoff in the field sometimes reaches as high as 30kg per minute, so it has not yet met the requirements for field observations in various situations.
