Rainfall simulation technique is used worldwide to identify and assess the nature and pattern of rainfall occurring in any particular area and its impact on the soil taking into consideration the various climatic and topographical factors. Whenever rainfall occurs heavily, it generates some unwanted physiographical processes such as high run-off, flood, soil erosion of different forms, landslides, etc. thereby redistributing the soil far from its original placement and sometimes rearranging the land topography to a large extent. Due to occurrence of flood, crops in agricultural fields get damaged and also quality of soil deteriorates resulting in incapability to produce crop in the future, to its full potential. Hence for evaluating the influence of rainfall on soil and water dynamics under varied conditions of land slope, rainfall intensities, soil types, soil infiltration rates, rainfall simulators of different types depending upon the need, are being considered as the best solution in the present day scenario. Rainfall simulators are generally laboratory based models which duplicate natural rainfalls and are designed considering various parameters as and when required. In the present paper, a number of important literatures on the role of rainfall simulators in identification and mitigation of rainfall created problems in various sectors concerning humans, such as soil erosion in agricultural fields, floods causing landslides, etc. have been collected and studied in depth for better understanding of those simulators of different types, based on the need and area of study by taking into account the various parameters concerning their studies.
