Tipping Bucket Prototype for Automatic Quantification of Surface Runoff Rate in Plots
ABSTRACT: Quantification of runoff rate is an onerous task with non-automated devices; it requires a lot of manual labor to perform measurements. In this study, an automatic device to quantify the surface runoff rate from plots with a small area was developed and tested. The prototype was based on the tipping bucket technique and built with reused materials. Its performance was tested in the laboratory and a calibration curve was developed to improve measurement accuracy. The device can be used for automatic quantification of surface runoff in small plots, with a flow rate of less than 750 × 103 mm3 min-1. The device can be built with different dimensions to measure different flow rates. In that case, the error measurements and calibration curve must be recalculated.
