Embodiment Construction
[0010] The implementation mode takes the working principle description as an example.
[0011] (1) Rainfall and snowfall are accessed from the upper port 11 of the measuring cylinder 12 for surface runoff measurement, and the precipitation Q 降 Measured by automatic rain gauge 23. The surface runoff Q generated in the measuring cylinder 径 From the runoff communication pipe 8, it is sent into the water quantity counter 6, and after metering, it enters the runoff water bucket 4, and after accumulation, it is discharged out of the runoff well 3 by the micro water pump 5.
[0012] (2) Measurement of underground seepage
[0013] The amount of seepage water that infiltrates into the ground Q 渗 It is sent to the water volume counter through the runoff communication pipe 13, and enters the seepage bucket 15 after metering, and is discharged outside the seepage bucket by another micro-water pump 5. Seepage bucket 15, undertakes seepage water volume, and volume is smaller than runoff...
