Abstract Morphometric indices from high-resolution DEMs can contribute to the estimation of flash flood susceptibility in mountainous areas. We have screened 25 morphometric commonly used literature, and based on a correlation matrix, selected those which showed strongest relationship with generation: area ( A ), drainage texture (Rt), density (Dd), elongation ratio (Re), form factor (Ff), lemn...

The purpose of this study is to determine the hydrological characteristics and morphometric parameters Sokouraba watershed (BV) where climatic hazards make water resource increasingly insufficient. This has never been subject characterization in past. present made it possible thus, better understand functioning hydrographic networks as well quantity likely be used for construction a dam watersh...

the response of karoun basin in lumped and semi-distributed simulation were compared. also, the flood intensity of the sub-basins and the effects of physical parameters on flood hydrograph have been investigated. results demonstrated that there was no significant difference between the characteristics of flood hydrograph in lumped and semi-distributed simulation. also, results showed that the f...

Peak discharge is one of the basic parameters in the design of hydraulic structures. There are various methods for peak discharge determination. Regional flood frequency analysis is based on physical, climatological and hydrological characteristics of basins. The objective of this study is to examine different models for the estimation of quantiles for some catchments in western Iran (namely: G...

The congruence coefficient was first introduced by Burt (1948) under the name of unadjusted correlation as a measure of the similarity of two factorial configurations. The name congruence coefficient was later tailored by Tucker (1951, see also Harman, 1976). The congruence coefficient is also sometimes called a monotonicity coefficient (Borg & Groenen, 1997, p. 203). The congruence coefficient...

The congruence between two configurations of points quantifies their similarity. The configurations to be compared are, in general, produced by factor analytic methods which decompose an “observations by variables” data matrix and produce one set of factor scores for the observations and one set of factor scores (i.e., the “loadings”) for the variables. The congruence between two sets of factor...

Araştırma Burdur Gölü Havzasının morfometrik analiz parametrelerini belirlemek amacıyla yapılmıştır. Ayrıca parametreler yardımıyla havzadaki erozyon durumu değerlendirilmiştir. Araştırmanın veri altyapısı SRTM (Shuttle Radar Topography Mission)’den elde edilen Sayısal Yükseklik Modeli (SYM) kullanılarak oluşturulmuştur. Analizlerde kullanılan akarsu dizinlerinin belirlenmesi ArcGIS 10.2 progra...
