Deep critical zone controls on shallow landslides

Seulgi Moon, Giuseppe Formetta, Justin T. Higa, Riccardo Busti et autres

The deep critical zone (CZ) has long been recognized for its importance in influencing shallow landslides but was not considered feasible to include in slope stability models at the watershed scale. Here, we demonstrate that simple approximations of the CZ in a …

Connectivity between hillslope and channel sediment stores and links to cascading hazards in the Indian Himalaya

Erin L. Harvey, Fiona Jane Clubb, David Graham Milledge, Hugh Denny Sinclair et autres

Flood frequency and magnitude in the Himalaya are projected to increase over the next century due to accelerating glacier melt and more intense monsoons. Most research has focused on the upstream triggers of floods, such as glacial lake outbursts, avalanches, or intense …

Optimising Gully Blocks to Reduce Flood Discharge

Sarah Lauren Drummond, David Graham Milledge, Caspar Hewett

Flooding is the most frequent and socially disruptive natural hazard observed worldwide and is expected to increase in severity under climate change and due to urban expansion. This has prompted research in upland natural flood management (NFM) strategies and in using gully …

Detection of landslide timing, reactivation and precursory motion during the 2018, Lombok, Indonesia earthquake sequence with Sentinel-1

Katy Burrows, David Graham Milledge, Maria Francesca Ferrario

Earthquake-triggered landslides can be mapped using optical satellite images, but assessing how they evolve during earthquake sequences is difficult due to cloud cover in these data. This information is crucial for understanding their triggering conditions. Here we use Sentinel-1 amplitude and a …

Interdisciplinary perspectives on the intersections of roads, sustainable development, and disaster resilience

Ellen B. Robson, Peter McGowran, Hanna A. Ruszczyk, Bruce D. Malamud et autres

Natural hazard-influenced disasters, sustainable development, and roads are closely intertwined. Governments and funding agencies worldwide are increasingly focused on delivering disaster-resilient road infrastructure. However, the multifaceted, ubiquitous, and contested nature of road networks means that making them resilient to disasters is a …

Large cobblestone dams for natural flood management in wide peatland gullies

Adam Johnston, David Brown, Tim Allott, Salim Goudarzi et autres

Peatland restoration is increasingly used for natural flood management (NFM). In the restoration of heavily degraded blanket peatland sites, erosional gully blocking is used to capture sediment and rewet peat in smaller peat gullies. There is limited prospect for restoration of wider …

Electro-mechanical insights into the mixing of conductive and non-conductive sands at an interface

Chao Zhang, Sadaf Maramizonouz, David Graham Milledge, Roger Lewis et autres

This paper investigates the electrical behaviour of an electrically conductive sand particle when mixed with non-conductive silica sand , commonly used in the railway industry. Laboratory tests and numerical simulations are conducted to assess the effect of mixing on the electrical conduction …

Dynamic risk from sediment cascades in the Indian Himalaya

Hugh Denny Sinclair, Rajiv Sinha, Fiona Jane Clubb, Erin L. Harvey et autres

Sediment cascades from the high mountains of the Himalaya are initiated in steep glaciated and fluvial landscapes and transfer downstream through alluvial and bedrock reaches of the river network before exiting at the mountain front. Understanding how the stochastic triggers for processes …

Boundary Effect Correction of the Infinite Slope Model for Saturated and Unsaturated Soils

Wengui Huang, Fleur A. Loveridge, David Graham Milledge, Jian Ji

The infinite slope model (ISM) is a classical method for assessing the stability of shallow landslides, dating back to the seminal works of Taylor (1948) and Skempton and DeLory (1957). Its simplicity has led to widespread adoption in routine analysis and physics-based …
