Document Type: Journal Paper


The available methods of predicting storm runoff from small watersheds and the factor which limit their use and predictive accuracy are reviewed to a deliberately broad-brush treatment designed to clarify the basic issues for practicing civil engineers without specialized training in hydrology. The methods can be broadly divided according to their basic data requirements, one group being essentially based on runoff records, the other on records of rainfall. The principal limitations encountered in attempting to apply methods from either category over extensive geographical areas arise from a) regional climatic differences, b) differences in basin characteristics, c) availability of basic data, and d) questions of statistical significance.
