A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Increasing urban flash flood risk attributable to both climate and development

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

Influence of meteorological factors, snow properties and climatic changes on evaporation from the snow cover surface

open access: yesВодное хозяйство России: проблемы, технологии, управление, 2023
The contribution of evaporation from the surface of the snow cover to the water balance of the land surface is a little-studied area of hydrology. Th e growing relevance of these studies increases with climate warming and more active involvement of the ...

Snow and ice in hydrology

open access: yesEos, Transactions American Geophysical Union, 1973
Joint symposia on the role of snow and ice in hydrology, sponsored by Unesco and WMO, were convened concurrently in September 1972 at the Banff School of Fine Arts, Banff, Alberta. Opening of the sessions was appropriately marked with an early season snowfall.

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

Snowpack properties vary in response to burn severity gradients in montane forests

open access: yesEnvironmental Research Letters, 2019
Wildfires are altering ecosystems globally as they change in frequency, size, and severity. As wildfires change vegetation structure, they also alter moisture inputs and energy fluxes which influence snowpack and hydrology.

Computational provenance in hydrologic science: a snow mapping example [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008
Computational provenance—a record of the antecedents and processing history of digital information—is key to properly documenting computer-based scientific research. To support investigations in hydrologic science, we produce the daily fractional snow-covered area from NASA's moderate-resolution imaging spectroradiometer (MODIS).

Future changes in population exposure to snowfall extremes across Eurasia

open access: yesRiver, EarlyView.
Abstract Extreme snowfall events have frequently occurred across parts of Eurasia, causing substantial economic losses and severe societal impacts. As global warming intensifies, assessing its potential effect on population exposure to such extremes becomes increasingly crucial. This study employed CMIP6 model datasets and future population projections

Learning to filter: snow data assimilation using a Long Short-Term Memory network [PDF]

open access: yesThe Cryosphere
Trustworthy estimates of snow water equivalent and snow depth are essential for water resource management in snow-dominated regions. While ensemble-based data assimilation techniques, such as the Ensemble Kalman Filter (EnKF), are commonly used in this ...
