While the Haile method resulted in the smallest MAREM,D value, the average slope of the estimated vs. observed floods is considerably less than 1, indicating that the Haile method generally underestimates the floods computed from the observed data. hide caption. J. /Parent 2 0 R Alexander (1990, 2001) recommended the use of the LP3 probability distribution for design flood estimation in South Africa, while Grgens (2007) used both the LP3 and GEV distributions and, according to Van der Spuy and Rademeyer (2010), both distributions are applicable in South Africa. 356 pp. West Virginia state Sen.
