Abstract

Hydrological techniques for the estimation of floods have not advanced much since the development of unit hydrograph methods in the 1930s. The technique of discounting losses using a coefficient has been readily adopted without a great deal of thought. The linear hydrological methods have all sprung from the same reasoning. It is invariably assumed that the design storm for any catchment is that with a duration corresponding to the travel time down the catchment. The flood due to 2 mm of effective rainfall Is assumed to be twice that due to 1 mm of rainfall.
