| Note générale : |
A simple apparatus is described for evaluating the energy load and intensity pf rainstorms relevant to studies of soil erosion and surface run-off. The instrument records graphically, on a time scale, the amplitude of electric pulses originating from the impact of raindrops on the surface of a tansducer dise, by making use of the piezo-electric effect. The size distribution of raindrops is calculated by analysing the graphic records of pulses on the chart from the number and the amplitude of pulses, and from the measured volume of total rainfall. The apparatus can be assembled using commercially available materials and recorders. It combines easy handling with acceptable accuracy. |
