Abstract
Rainfall Simulators are widely used in studies on soil erosion. Most of the rainfall simulators use water with tap or ambiance temperature. However, previous studies showed that soil erosion may increase or decrease by up to three times while raindrops temperature varied from 2 °C to 20 °C. Therefore, it is of great importance to use a temperature control system in rainfall simulators. This paper describes the design of a temperature control system suitable for a rotating disk rainfall simulator at the Soil and Geomorphology Laboratory in Bar-Ilan University. The rain temperature is continually monitored by thermocouples, located very close to the disk. IR remote sensing results showed that the real temperature of the drops hitting on the ground surface differed from that measured with thermocouples by maximum 1° for the coldest simulated rain (2 °C), and −3° for the hottest one (35 °C), hence the continually monitoring temperature error is negligible.
