one of the most appropriate approaches for flood forecasting is using peak discharge data of hydrometric stations in each region. however, lack of such stations or short duration of data in most parts of the country, make it necessary to use some alternative methods in order to estimate the flood discharge properly. one of these approaches is regional flood analysis method that in a region usin...

Z. W. Kundzewicz

A holistic perspective on changing river flood risk in Europe is provided. Economic losses from floods have increased, principally driven by the expanding exposure of assets at risk. Climate change (i.e. observed increase in precipitation intensity, decrease of snowpack and other observed climate changes) might already have had an impact on floods. However, no gauge-based evidence had been foun...

Cluckie (1990) states that "when a site has about 40 or 50 years of record it is unlikely to contribute significantly to the improvement of a regionally based statistical estimate by the availability of more data". In the present paper, the authors conclude that "databases with more than 300 station-years can be considered in a quite good condition in terms of quantity of information and that, ...

Regional Flood Frequency Analysis (RFFA) is an efficient method in flood discharge estimation in ungauged watersheds or with short-term statistics. The purpose of the present study is to evaluate the hybrid method in RFFA and maximum flood discharge estimation in the Namak Lake watershed, Iran. For this purpose, 16 hydrometric stations were selected. The selected hydrometric stations were then ...

Due to climate change, the frequency and intensity of Hydro-Meteorological disasters, such as floods, are increasing. Therefore, the main purpose of this work is to assess tangible future flood damage in the urban watershed of the To Lich River in Hanoi, Vietnam. An approach based on spatial analysis, which requires the integration of several types of data related to flood characteristics that ...

Background: Magnitude, rate and frequency of the stochastic and unexpected events are of great significance and importance in hydrology. Nowadays, for economic planning of the projects, the use of analytical methods of unexpected events in hydrology is unavoidable. The aim of this study was to compare hybrid regression and multivariate regression to estimate flood peak discharge in the province...
