Subjects: Applied Mathematics, Earth Sciences, Glaciology, Hydrology, Physical Sciences and Mathematics, Soil Science

Frost heave occurs when the ground swells during freezing conditions due to the growth of ice lenses in the subsurface. The mechanics of ice-infiltrated sediment, or frozen fringe, influences the formation and evolution of ice lenses. As the frozen fringe thickens during freezing, progressive unloading can result in dilation of the pore space and the formation of new ice lenses. Compaction can [...]

Skilful probabilistic predictions of UK floods months ahead using machine learning models trained on multimodel ensemble climate forecasts

Simon Moulds, Louise Slater, Louise Arnal, et al.

Seasonal streamflow forecasts are an important component of flood risk management. Hybrid forecasting methods that predict seasonal streamflow using machine learning models driven by climate model outputs are currently underexplored, yet have some important advantages over traditional approaches using hydrological models. Here we develop a hybrid subseasonal to seasonal streamflow forecasting [...]

Increasingly seasonal jet stream drives stormy episodes with joint wind-flood risk in Great Britain

John Hillier, Hannah Bloomfield, Colin Manning, et al.

Published: 2024-07-03
Subjects: Applied Statistics, Atmospheric Sciences, Climate, Hydrology, Multivariate Analysis

Ignoring a correlation between flooding and extreme winds underestimates risk to insurers or providers of critical infrastructure such as railways or electricity. We explore this potential underestimation for Northwest Europe, illustrated using Great Britain (GB), using an event-based analysis in regional 12 km UK Climate Projections (UKCP18, 1981-1999, 2061-2079 – RCP8.5). We derive a new [...]

Machine Learning-based Hydrological Models for Flash Floods: A Systematic Literature Review

Background: Flash flood modeling faces many challenges since physically-based hydrological models are unsuitable for a small spatiotemporal scale. With the increased availability of hydrological observed data, an alternative approach is to use Machine Learning (ML) techniques. This work conducts a Systematic Literature Review (SLR) to enhance our comprehension of the research landscape on [...]

Coastal settlements, facing increasing flood risk from Tropical Cyclones (TCs) under climate change, need local and detailed climate information for effective adaptation. Analysis of historical events and their impacts provides such information. This study uses storylines to evaluate adaptation strategies, focusing on Cyclone Idai’s impact on Beira, Mozambique, under different climate [...]

Rising temperatures drive lower summer minimum flows across hydrologically diverse catchments

Sacha W Ruzzante, Tom Gleeson

Published: 2024-05-25
Subjects: Hydrology, Water Resource Management

Excessively low stream flows harm ecosystems and societies, so two key goals of low-flow hydrology are to understand their drivers and to predict their severity and frequency. We show that simple linear regressions can accomplish both goals across diverse catchments. We analyse 230 unregulated moderate to high relief catchments across rainfall-dominated, hybrid, snowmelt-dominated, and glacial [...]

Archetypal flow regime change classes as signatures of anthropogenic drivers of global streamflow alterations

Vili Virkki, Reetik Kumar Sahu, Mikhail Smilovic, et al.

Published: 2024-05-14
Subjects: Hydrology

Streamflow – a key component of the water cycle – is experiencing drastic alteration due to human actions. While existing studies have widely assessed the global extent and degree of this change, understanding of its drivers has been limited because previous global-scale approaches have largely relied on modelled hypothetical scenarios. Here, we overcome these limitations by providing a [...]

Fine-resolution spatial patterns of water table depth (WTD) play a crucial role in shaping ecological resilience, hydrological connectivity, and anthropocentric objectives. Generally, a large-scale (e.g., continental or global) spatial map of static WTD can be simulated using either physically-based (PB) or machine learning-based (ML) models. We construct three fine-resolution (500 m) ML [...]

Limited role of discharge in global river plastic transport

Caspar Roebroek, Adriaan J Teuling, Martine van der Ploeg, et al.

Published: 2024-04-23

River plastic transport has been assumed to be driven by river discharge, although observational data does often not support this. We propose a new perspective that describes plastic transport as function of plastic availability and transport capacity. Plastic transport is under most circumstances driven by plastic availability, which is largely disconnected from river discharge. However, when [...]
