Seven case studies are presented, demonstrating the successful use of a laboratory‐based drip‐screen rainfall simulator at Coventry University to investigate several hydrological, pedological and geomorphological problems. The results of previously unpublished studies are presented in full, while the salient points of published studies are discussed. Synthesis of the experimental results led to the recognition of various philosophical and practical problems associated with the realistic simulation of rain, which need to be addressed in future research. Particular problems are posed by the variety of analytical approaches and simulator designs, as they impede meaningful inter‐laboratory comparisons. It is argued that future improvements require optimization, harmonization and standardization of analytical procedures and rainfall simulators. An ideal approach would be the development of a European key laboratory to offer realistic and standardized simulation conditions. Copyright © 2000 John Wiley & Sons, Ltd.
