Information on extreme rainfall frequencies is required for Urban Drainage (UD) networks design. In this paper, the Regional Frequency Analysis (RFA), based on the L-moments, is used to: (i) analyze the trend of Annual Maximum Precipitation (AMP) over two analysis periods (1970–1989 and 1990–2015), (ii) estimate the regional Intensity-Duration-Frequency (IDF) curves of northern Morocco and (iii) assess the impact of the changes in rainfall intensities on the UD networks design during analysis periods.In reference to Hosking & Wallis (1997) and Alila, (1999), the Generalized Extreme Value (GEV) distribution has been used as a regional distribution to estimate regional quantiles for the analysis periods (1970–1999 and 1990–2015). The results show an increase up to 9% for quantiles used in UD networks design. Keywords: Regional frequency analysis, Extremes precipitations, L-moments, GEV distribution, Urban drainage |
