Sensitivity of flood frequency analysis to data record, statistical model, and parameter estimation methods: An evaluation over the contiguous United States

Journal of Flood Risk Management, 2019
The current statistical methods applied in flood frequency analysis require long data records to obtain reliable estimates, particularly for long return periods.

Can we still predict the future from the past? Implementing non‐stationary flood frequency analysis in the UK

Journal of Flood Risk Management, 2019
The Environment Agency in England is investing £2.5 billion with the aim of reducing flood risk to at least 300,000 homes by 2020/21. Several of the schemes being considered are on rivers that have experienced an upsurge of flooding over recent years ...

Comparative analysis of flood and rainfall frequency in the ungauged sub-watersheds of Kakia and Esamburumbur in Narok town, Kenya, using the EBA4SUB rainfall-runoff model

Journal of Agricultural Engineering, 2022
Knowledge of design peak flow is crucial in various applications related to hydrology, hydraulics and water resources management. However, obtaining design peak flow is challenging especially in ungauged basins lacking of discharge observations, a ...

Transposing flood risk from extreme rainfall events: A case study of Hurricane Harvey

Journal of Flood Risk Management, 2022
Hurricane Harvey produced unprecedented flooding that altered flood frequency statistics near Houston, Texas. While Harvey could have made landfall elsewhere along the Gulf coast, traditional flood frequency methodologies only consider the risk of Harvey

Quantitative analysis of the impacts of climate and land-cover changes on urban flood runoffs: a case of Dar es Salaam, Tanzania

Journal of Water and Climate Change, 2021
Over the past half-century, the risk of urban flooding in Dar es Salaam has increased due to changes in land cover coupled with climatic changes. This paper aimed to quantify the impacts of climate and land-cover changes on the magnitudes and frequencies

Sampling uncertainty of UK design flood estimation

Hydrology Research, 2021
The UK standard for estimating flood frequencies is outlined by the flood estimation handbook (FEH) and associated updates. Estimates inevitably come with uncertainty due to sampling error as well as model and measurement error.
