DEVELOPMENT AND COMPARISON OF DIFFERENT INTENSITY DURATION FREQUENCY MODELS FOR CALABAR, NIGERIA

This paper is aimed at developing and three years peak rainstorm intensity data with their corresponding durations Nigerian Meteorological Agency, Calabar, exponential, logarithmic and power intensity between 2 years and 100 years using rainfall intensity data for durations of and 320 minutes. A comparison between the predicted results by the three models revealed that the logarithmic model yielded the closest intensity values to the logarithmic and power models gave and 0.848 (0.558±0.197) and0.004 logarithmic model yields comparatively ensure adequate sizing and forecast of relevant hydraulic structure
