These estimations are determined to assign hydrological and hydraulic dimensions to bridges, sewers, dam, spillway, protection embankments, weirs, detention ponds and diversion canals. Gumbel’s Method The extreme value distribution was an introduction by Gumbel (1941) and is commonly known as Gumbel’s distribution.
