Extreme environmental events, such as floods, droughts, rainstorms and high winds, have severe consequences for human society. Regional frequency analysis helps to solve the problem of estimating the frequency of these rare events at one site, by using data from several sites. This book is the first complete account of the L-moment approach to regional

Regional Flood Frequency Analysis using L-Moments
Civil-Comp Proceedings, 2009Regional flood frequency analysis was performed using L-moments. The analysis uses annual maximum flood data observed at a desired project location or streamgaging station to estimate flood quantiles. Regional flood frequency analysis involves four stages: screening of the data, identification of homogeneous regions, choice of a regional frequency ...

Regional Frequency Analysis of Extreme Groundwater Levels
Groundwater, 2014Abstract Flood risk is generally perceived as being a consequence of surface water inundation. However, large damage is also caused by high groundwater levels. In surface hydrology, statistical frequency analysis is a standard tool to estimate discharge with a given return period or exceedance probability.

Regional Analysis of Sinonasal Ciliary Beat Frequency
American Journal of Rhinology, 2006Background Mucociliary clearance, a primary host defense mechanism, depends on mucus production and its clearance by the coordinated beating of cilia lining the airways. Numerous investigations have analyzed ciliary activity in brushings from the inferior turbinate. To date, only one study has investigated whether there exists variation in ciliary beat

Regional Drought Frequency Analysis
Journal of the Irrigation and Drainage Division, 1966Analysis of severity and duration of droughts in central United States and Massachusetts is compared with available drought data from California, the Clearwater River, Illinois, the Soviet Union, and the Nile River. Considerable basic differences in drought occurrence are found to characterize the different regions.

Regionalization of Catchments for Regional Flood Frequency Analysis
Journal of Hydrologic Engineering, 1997An approach to catchment regionalization is presented, in which an agglomerative hierarchical clustering algorithm is used to define homogeneous regions that can be used for regional flood frequency analysis. Catchment similarity is expressed using seasonality measures derived from the mean date of occurrence of the annual maximum flood and its ...

Regional flood frequency analysis using complex networks
Stochastic Environmental Research and Risk Assessment, 2021Proper regionalisation (identification of homogeneous regions) is key to reliable regional flood frequency analysis. Several methods have been proposed in the literature for regionalisation, including the method of residuals, L-moment method, and fuzzy c-means clustering algorithm.

Regional Frequency Analysis of Droughts in Portugal
Water Resources Management, 2011This study investigated the frequency of droughts for the period September 1910 to October 2004 in mainland Portugal, based on monthly precipitation data from 144 rain gauges distributed across the country. The drought events were characterized using the standardized precipitation index (SPI) applied to time scales of 1, 3, 6 and 12 consecutive months.
