statistical frequency analysis is the most common procedure for the analysis of flood data at a gauged location thatin first step it is needed to select a model to represent the population. among them, the central moment has been themost common and widely used, and with the using of computers, the application of the maximum likelihood hasincreased. this research was carried out in order to reco...

There has been an increase in the occurrence of sudden local flooding of great volume and short duration caused by heavy or excessive rainfall intensity over a small area, which presents the greatest potential danger threat to the natural environment, human life, public health and property, etc. Such flash floods have rapid runoff and debris flow that rises quickly with little or no advance war...

A common problem encountered by catchment managers is the estimation of design peak flow quantiles. Current practice, as discussed by Pilgrim (1987), is based either on the use of statistical approaches such as an at-site flood frequency analysis, or the use of a catchment modelling system to simulate catchment response to design rainfall. For many practical problems, the option of an at-site f...

SUPPLEMENTARY INFORMATION: The Federal Emergency Management Agency (FEMA) publishes proposed determinations of Base (1% annualchance) Flood Elevations (BFEs) and modified BFEs for communities participating in the National Flood Insurance Program (NFIP), in accordance with section 110 of the Flood Disaster Protection Act of 1973, 42 U.S.C. 4104, and 44 CFR 67.4(a). These proposed BFEs and modifi...

In this study, the flood, occurred in Besikduzu District, Trabzon, on 21 September 2016 and resulted large amount of life loss property, was investigated terms hydrological social aspects. For purpose, firstly, various flood discharges for different return periods were estimated by regional frequency analysis order to determine quantile flood. Secondly, determining risk awareness needs early wa...

a sensitivity analysis of the flood safety of solaimantangeh dam using a regional climate change simulation is presented. based on the output of the ccsm (community climate change system model) general circulation model, the nircm (north of iran regional climate model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. using the sres (special report emission sc...
