Abstract

Detachment of soil particles from soil surface depends on the kinetic energy imparted by a rainfall event. Therefore, it is essential to estimate kinetic energy as accurately as possible to enable study of soil erosion and infiltration mechanisms. Owing to a number of advantages, rainfall simulation is widely used to generate rainfall of desired intensities and durations to study soil erosion, infiltration and other dynamic behaviours of soil. An experimental setup was devised to estimate the kinetic energy of three different simulated rainfall events produced by three different combinations of pressures and nozzle sizes. The equipment consisted of a multipurpose hydraulic flume, 2m long and 1.4m wide. Five highly sensitive force transducers were mounted on the surface of the flume to measure the impact of raindrops. Two tipping bucket rain gauges were used to measure rainfall intensity. Responses received from the transducers (in the form of voltage) and from the tipping bucket (in the form of pulses) were recorded at regular interval. Data collected were analysed to estimate the kinetic energy and the findings are presented here.
