Flood frequency analysis

open access: yesEos, 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 ...

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

open access: yesAdvanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Understanding the Impact of Precipitation Bias‐Correction and Statistical Downscaling Methods on Projected Changes in Flood Extremes

open access: yesEarth's Future
This study evaluates five bias correction and statistical downscaling (BCSD) techniques for daily precipitation and examines their impacts on the projected changes in flood extremes (i.e., 1%, 0.5%, and 0.2% floods). We use climate model outputs from the

Modelling non-stationary flood frequency in England and Wales using physical covariates

open access: yesHydrology Research
Non-stationary methods of flood frequency analysis are widespread in research but rarely implemented by practitioners. One reason may be that research papers on non-stationary statistical models tend to focus on model fitting rather than extracting the ...

Preliminary Probe on Basic Concept of Flood Risk for Wading Project

open access: yes工程科学与技术, 2021
Flood risk is a very important subject in hydrology. Firstly, the exact meaning of flood risk has been discussed, and two concepts of flood risk in the current situation, time risk and annual risk, have been pointed out.

Assessment of antecedent moisture condition on flood frequency: An experimental study in Napa River Basin, CA

open access: yesJournal of Hydrology: Regional Studies, 2019
Study region: This study region is the Napa River basin in California whose antecedent soil moisture states and precipitation magnitudes are primary drivers to occur extreme floods.

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.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Hydrometeorological Trends in a Low-Gradient Forested Watershed on the Southeastern Atlantic Coastal Plain in the USA

open access: yesHydrology
Hydrology and meteorological data from relatively undisturbed watersheds aid in identifying effects on ecosystem services, tracking hydroclimatic trends, and reducing model uncertainties.
