The paper describes six alternative equations for predicting mean annual flood from catchment characteristics, developed in and subsequent to the UK Flood Studies Report and tested for ten small catchments in Northern Ireland. The most satisfactory equation was found to be one developed in the mid‐1980s for large catchments in the Province. Equations which were developed using small‐catchment data from elsewhere in the UK performed less well. The paper considers whether there is a real difference in the behaviour of small and large catchments in Northern Ireland, and examines alternative methods of estimating the mean annual flood in partly‐urbanised areas.
