SIMULATION OF SCOURING AROUND A VERTICAL CYLINDER DUE TO TSUNAMI [PDF]

Science of Tsunami Hazards, 2017
* Corresponding author radianta@ugm.ac.id ABSTRACT Local scour due to tsunami is damaging especially on shallow foundation. Although relatively in a short duration, tsunami attack may scour material around buildings that led to destruction. A number of

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

People and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Rewilding's technological experiments: Virtual reality and scalable narratives of rewilding in the Scottish highlands

People and Nature, EarlyView.
Abstract Depictions of rewilded landscapes reveal the underlying principles shaping the future of rewilding. This paper analyses a virtual reality (VR) model of a rewilding project in the Scottish Highlands that is advertised as a vision of a rewilded nature in 50 to 100 years' time.

Scour effects on p-y curves for shallowly embedded piles in sand

, 2016
Soil scour around a shallowly embedded pile can significantly compromise its lateral response, reducing both stiffness and capacity. Estimation of the lateral pile response must take into account both the scour-hole geometry and the overconsolidation ...

Increased utilitarian value of invasive species in regions with long invasion history may limit public engagement for invasion control

PLANTS, PEOPLE, PLANET, EarlyView.
Positive perceptions of invasive species can hinder effective management, especially if management efforts that are rooted in scientific theories are misaligned with local ecological knowledge. We documented local ecological knowledge about land invasibility as predicted by invasion biology theories. Participants with greater local ecological knowledge

Assessment of the impacts of local scour at bridge piers on the stability of ice jams – An experimental study

Hydrology Research
Local scour at the bottom of bridge piers further affects the stability of ice jams. In this study, the experimental study on the influence of local scour on the stability of ice jams at the pier was carried out, and the test conditions of different ...

A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

River Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Ecohydrology‐Informed Machine Learning for Floodplain Vegetation Classification to Support Riverine Nature‐Based Solutions

Remote Sensing in Ecology and Conservation, EarlyView.
Ecohydrological theory was used to inform supervised machine learning algorithms through a novel multidisciplinary data fusion approach for vegetation and habitat classification in a large river floodplain, an ecosystem of high biodiversity, landcover heterogeneity, and conservation importance.

Theoretical framework for updating cross‐sections in river models using non‐standard information coming from crowdsourced images

River, EarlyView.
Abstract During high rainfall events, one reason for flooding in urban rivers is hydraulic blockages or obstructions in channels. These may cause damming and an immediate increase in upstream water levels, leading to inundation of surroundings. The accuracy of flood models is strongly dependent on the representation of the topography of floodplain and ...

A semi-empirical prediction model for scour depth around riprap-protected monopiles under steady currents

Applied Ocean Research
Local scour around monopiles remains a major concern for offshore foundations, and riprap protection is widely used to mitigate scour. However, residual deformation and scour within riprap protection layers may still occur, and their prediction remains ...
