“…One of the prevalent approaches for delineating homogeneous regions is based on clustering techniques (Clarke, 2011;Guse et al, 2010;Everitt, 2001;Zrinji and Burn, 1996;Aldenderfer and Blashfield, 1984;Roger, 1980) and have been applied in many flood frequency analysis studies (e.g., Clarke, 2011;Ramachandra Rao and Srinivas, 2005;Kachroo et al, 2000;Kim and Hawkins, 1993;Acreman and Sinclair, 1986). However, application of the different clustering techniques to the same dataset, normally leads to different results (Lubomír, 2005).…”
