“…Estimates of design floods are often missing to initiate any hydraulic modeling for water infrastructures in the region (Zemzami et al 2012). IDF curves are often used to estimate future rainfall intensities based on the Talbot-Montana model (Moujahid et al 2018). However, these curves need to be updated by DGM for each meteorological station as climate change has considerably affected their accuracy.…”

From ancient flood management practices driven by agricultural activities to dam’s policy for water resources management including flood protection, to the National Strategy for Natural Disaster Risk Integrated Management; Morocco has come a long way in flood risk management. This chapter describes the recurrent flooding phenomenon plaguing the country along with progress in flood risk assessment approaches in terms of technique, governance, and best practices. An extensive number of research articles, administrative documents, consultancy, and international organizations reports are analyzed to give a holistic up-to-date insight into flood risk management in Morocco and present a comprehensive and critical view from a scientific perspective. Information and data were collected from a range of various sources and synthesized to integrate all scientific and governance aspects. Though analysis of this landscape shows progresses made by the Government to protect the population and reduce flood risk, it also shows shortcomings and challenges still to be overcome. Thus, a SWOT analysis was carried out for scoping and identifying the strengths, weaknesses, opportunities, and threats pertaining to this issue. The analysis reveals various success and failure factors related to three major components: governance, risk assessment approaches, and flood risk mitigation measures sustainability.

“…Some studies have shown the inadequacy of the Gumbel distribution for measuring annual rainfall maxima, as it implies much lower quantiles of extreme rainfall when compared to the general form of extreme distributions, generalized extreme value distribution (GEV) [12]. Moreover, the issue of such a debate between Gumbel and GEV distributions is considerable, since it is related to IDF curve estimation.…”

Intensity–duration–frequency (IDF) curves of precipitation are a reference decision support tool used in hydrology. They allow the estimation of extreme precipitation and its return periods. Typically, IDF curves are estimated using univariate frequency analysis of the maximum annual intensities of precipitation for different durations. It is then assumed that the annual maxima of different durations are independent to simplify the parameter estimation. This strong hypothesis is not always verified for every climatic region. This study examines the effects of the independence hypothesis by proposing a multivariate model that considers the dependencies between precipitation intensities of different durations. The multivariate model uses D-vine copulas to explore the intraduration dependencies. The generalized extreme values distribution (GEV) is considered a marginal model that fits a wide range of tail behaviors. An illustration of the proposed approach is made for historical data from Moncton, in the province of New Brunswick (Eastern Canada), with climatic projections made through three scenarios of the Representative Concentration Pathway (RCP).

“…RFA has been extensively applied to estimate the return periods of various weather-related variables, such as those in [18][19][20][21][22][23]. e identification of homogeneous regions is carried out using cluster analysis, based on the latitude, longitude, altitude, and daily average rainfall recorded at each station.…”

Drought is a condition of a shortage of water that has an impact on economic activity. This research studies the severe drought area in Indonesia using Regional Frequency Analysis (RFA), based on daily precipitation data recorded at nine stations. The analysis reveals five homogeneous regions, based on discordancy and heterogeneity tests. Furthermore, the L-moment approach is applied to investigate the regional distribution and suggests that the Pearson type III distribution is the distribution that best fits the five regions. This distribution is also used to calculate the regional growth curve that is employed in the drought analysis. The drought return period analysis, for conditions of 40% of normal rainfall, concludes that the region containing the Fransiskus Xaverius, Gewayantana, and Mali stations has the highest drought risk, indicated by the fastest return period estimate of 2 years and 4 months. Moreover, the extreme drought analysis shows that two of the regions have the potential to experience the return of extreme drought, with less than 20% of normal rainfall, in less than four years.
