Abstract: The existing rainfall simulators were not able to reprove natural rainfall condition effectively. In view of this, a methodology for designing field rainfall simulator was reviewed with the objective of developing rainfall simulator that generates and reproduces rainfall condition. Monthly average rainfall intensity data is required to determine the median drop diameter of the rainfall simulator. Subsequently, the kinetic energy, flow rate and power requirement of the rainfall simulator should be calculated empirically. In addition, calibration of rainfall simulator in term of rainfall intensity, uniformity coefficient and kinetic energy is important for effective simulation with the natural rainfall. This review work found out that rainfall simulator could be used to develop models for predicting the fate and transport of pollutants in runoff. This review suggested that the effect of different pressurized nozzles on the intensity of rainfall simulator’s performance be examined after designing rainfall simulator. Thus, optimization of pressurized nozzles on the rainfall simulator are required for effective Coefficient and distribution uniformity of the system.
