Evaluation and projection of the annual maximum streamflow in response to anthropogenic and climatic effects under nonstationary conditions in the Hanjiang River Basin, China

open access: yesJournal of Water and Climate Change, 2022
The flood regimes have been changing due to the climate change and human activities. Evaluating the flood risk under nonstationarity is critical to water resource management authorities in disaster reduction. In this study, the annual maximum streamflow (

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

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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

Have applications of continuous rainfall-runoff simulation realized the vision for process-based flood frequency analysis? [PDF]

open access: yes, 2016
Keith Beven was amongst the first to propose and demonstrate a combination of conceptual rainfall–runoff modelling and stochastically generated rainfall data in what is known as the ‘continuous simulation’ approach for flood frequency analysis.

Sampling uncertainty of UK design flood estimation

open access: yesHydrology 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.

Operational Flood Risk Index Mapping for Disaster Risk Reduction Using Earth Observations and Cloud Computing Technologies: A Case Study on Myanmar

open access: yesFrontiers in Environmental Science, 2019
People, livelihoods, and infrastructure in Myanmar suffer from devastating monsoonal flooding on a frequent basis. Quick and effective management of flood risk relies on planning and preparedness to ensure the availability of supplies, shelters and ...

Logarithmic transformation and peak-discharge power-law analysis

open access: yesHydrology Research, 2020
The peak-discharge and drainage area power-law relation has been widely used in regional flood frequency analysis for more than a century. The coefficients and can be obtained by nonlinear or log-log linear regression.

Influence of solar forcing, climate variability and modes of low-frequency atmospheric variability on summer floods in Switzerland [PDF]

open access: yes, 2016
The higher frequency of severe flood events in Switzerland in recent decades has given fresh impetus to the study of flood patterns and their possible forcing mechanisms, particularly in mountain environments.

Flood Frequency Analysis Using Participatory GIS and Rainfall Data for Two Stations in Narok Town, Kenya

open access: yesHydrology, 2019
Flood management requires in-depth computational modelling through assessment of flood return period and river flow data in order to effectively analyze catchment response.
