The invention discloses a slope rill
erosion measurer which is characterized in that a
transverse beam which can slide up and down is connected with a
metal framework; one end of a measuring needle is provided with a
screw cap, and the other end of the measuring needle passes through the
transverse beam and then extends out of the framework; the upper end of the framework is provided with a level instrument and a transverse scale, and the lower end of the framework is connected with two fixed borers which can be inserted into a slope; one side of the framework is provided with a vertical scale and an
angle gauge, and the other side of the framework is connected with two positioning bolts; and the slope rill
erosion measurer can be connected with another measurer in parallel for use. When the measurer is vertically inserted into the slope, the measuring needle is used for measuring the amount of rill
erosion of soil of the slope, and the
angle gauge is used for measuring the gradient of the slope. The slope rill erosion measurer is suitable for measuring the amount of slope rill erosion in
field soil, has the advantages of simple operation and convenient carrying, and can be assembled and disassembled on the spot; a digital photographic technology can be used for quickly recording the measured data, thereby improving the measuring accuracy; and the
data processing at the later stage is relatively simple.
