• A laboratory catchment provides experimental control over hydrological variables which is notably absent in the monitoring of experimental and representative basins. In designing an apparatus for laboratory catchment studies, particular attention must be paid to the methods of simulating rainfall over, and of measuring discharge from, the artificial catchments. The former should reflect the importance of the several characteristics of natural rainfall to the purpose of the experiments, while the latter should be capable of registering instantaneous rates of runoff directly. Moreover, every effort should be made to employ the most efficient and economical methods of setting-up and recording the results of experiments. Data from such a facility at Imperial College, London, have been employed for the development and intercomparison of numerical models of overland flow. (DBO)
