The weight of the flood‐of‐record in flood frequency analysis

Journal of Flood Risk Management, 2018
AbstractThe standard approach to flood frequency analysis (FFA) fits mathematical functions to sequences of historic flood data and extrapolates the tails of the distribution to estimate the magnitude and likelihood of extreme floods. Here, we identify the most exceptional floods in the United States as compared against other major floods at the same ...

Flood frequency analysis [PDF]

, 2011
Floods can be characterised by peak flow, flood volume with a defined duration, or other attributes. They are considered as independent and identically distributed. Empirical flood frequency provides the basis for analytical flood frequency estimation. Computer software helps to speed up the frequency analysis process.

Non-Stationary Flood Discharge Frequency Analysis in West Africa

GeoHazards, 2023
With climate change and intensification of the hydrological cycle, the stationarity of hydrological variables is becoming questionable, requiring appropriate flood assessment models. Frequency analysis is widely used for flood forecasting.

Recent trends in the frequency and duration of global floods [PDF]

Earth System Dynamics, 2018
Frequency and duration of floods are analyzed using the global flood database of the Dartmouth Flood Observatory (DFO) to explore evidence of trends during 1985–2015 at global and latitudinal scales.

Flood Frequency Analysis of Main Nara Valley [PDF]

Mehran University Research Journal of Engineering and Technology, 2011
This paper deals with the flood of 2007 and its frequency analysis at MNY (Main Nara Valley), and generally describe flood of 2010 in Sindh Pakistan. Heavy monsoon rain and cyclones cause the flood conditions in Sindh.

Flood frequency analysis

Eos, Transactions American Geophysical Union, 1979
Panattoni and Wallis' treatment of the flood frequency analysis problem i s masterful; one hopes that its appearance will put and end to the proliferation of naive efforts to establish a nonsubjective statistical method. Their treatment of the systems analysis phase of the problem makes use of the latest computational techniques, but one doubts that ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Accounting for Hydroclimatic Properties in Flood Frequency Analysis Procedures

Hydrology and Earth System Sciences, 2022
Abstract. Flood hazard is typically evaluated by computing extreme flood probabilities from a flood frequency distribution following nationally defined procedures in which observed peak flow series are fit to a parametric probability distribution.
