Rainfall-Intensity Duration Frequency Analysis for urban flood management options within Gountiyena basin in Niamey, Niger, 2019

The data consists of annual maxima series of different time durations from 5 minutes to 24 hours for two stations for the period 1990 to 2017. The data was extracted from the AMMA CATCH database for the two stations NY_IRI and NY_ORSTOM located within the city of Niamey.

The Extracted Annual Maxima Series was used in the development of Intensity Duration Frequency Curves as well as for the Peak discharge estimations for the basin of interest
