Abstract
The invention relates to the technical field of slope surface water quantity balance field observation and in particular relates to a slope surface water quantity balance field observation system. Theslope surface water quantity balance field observation system comprises a slope surface runoff small region and a runoff silt collection device, wherein the slope surface runoff small region comprises a slope surface soil matrix; the upper surface of the slope surface soil matrix is gradually and obliquely arranged downward from right to left; a plurality of interflow water collection layers arearranged on the left side surface of the slope surface soil matrix from top to bottom; the runoff silt collection device comprises a plurality of water collection plates and a plurality of interflow water collection pipes, which correspond to the interflow water collection layers one by one; the interflow water collection pipes comprise an interflow main pipe and a plurality of interflow branch pipes; the interflow branch pipes are connected with interflow through holes in a one to one correspondence manner. The slope surface water quantity balance field observation system provided by the invention can be used for independently collecting runoff flow yield of each layer by layers and also can be used for preventing recharge loss of surface runoff and interflow, so that the water and soil loss of a slope surface is accurately measured.
Description
technical field [0001] The invention relates to the technical field of slope surface water balance field observation, in particular to a slope surface water balance field observation system. Background technique [0002] Slope water balance field is a common test facility for studying soil erosion process and slope soil erosion law by means of artificial or natural rainfall. Slope runoff has the characteristics of low head, small flow, and sandy flow, which makes runoff observation difficult. The sensitivity and accuracy of flow measurement devices are often affected by the complex field environment. The traditional slope water balance field is usually to establish a surface slope water collection tank at the low slope boundary of the slope runoff area, and then use the water collection pipe to directly import the runoff for observation. This kind of slope surface water balance field has a simple structure and can obtain a small amount of surface runoff, but it is difficult...
