Near‐seabed sediment dynamics and fluxes on Chatham Rise, the effects of seabed disturbance, and implications for deep‐sea bottom trawling and seabed mining

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1460-1495, December 2025.
ABSTRACT Anthropogenic impacts are increasingly affecting deep‐sea environments, including seafloor sediment disturbances by bottom trawling and seafloor mining. Fieldwork in the ‘Resilience Of Benthic Ecosystems to Sedimentation’ (ROBES) project were conducted in 2018–2020 on the 400 m‐deep Chatham Rise crest, eastern Aotearoa New Zealand.

NUMERICAL SIMULATION OF UJONG SEUDEUN LAND SEPARATION CAUSED BY THE 2004 INDIAN OCEAN TSUNAMI, ACEH-INDONESIA [PDF]

Science of Tsunami Hazards, 2015
The Aceh province in Indonesia, located around the Sumatra subduction area, was one of the worst hit areas with respect to damage from the impact of the 2004 Indian Ocean tsunami. A 9.15 Mw earthquake triggered the tsunami.

A Reduced‐Complexity Model to Predict Seasonal Variation in Estuarine Salinity

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Accurate prediction of seasonal variations in salinity is essential for assessing the health of estuarine environments. Traditional estuarine salinity models face challenges such as high computational demands and extensive data requirements.

A 2D Tide-Averaged Model for the Long-Term Evolution of an Idealized Tidal Basin-Inlet-Delta System

Journal of Marine Science and Engineering, 2018
We present a model for the morphodynamics of tidal basin-inlet-delta systems at the centennial time scales. Tidal flow is calculated through a friction dominated model, with a semi-empirical correction to account for the advection of momentum.

Unveiling the Stochasticity of Bank Erosion: A Hybrid Deterministic and Stochastic Modeling Approach

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract This paper presents a new hybrid deterministic‐stochastic river morphodynamics numerical modeling approach that integrates a hydrodynamic model (deterministic) with a bed morphodynamic model (deterministic) and a bank erosion model (Markovian stochastic).

Global Analysis of Storm Surge Seasonality

Journal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract We perform the first global analysis of storm surge seasonality using surge data from a global hydrodynamic model with full coverage of coastal areas, providing valuable insights for regions not represented in alternative observational data sources. We apply directional statistics based on the mixture model of the von Mises‐Fisher distribution

Modelling of Intense Rainfall-Induced Flash Flood Inundation Using Delft3D FM

Hydrology
Flash floods are among the most destructive hazards in northeastern Bangladesh, particularly in Sylhet district, where intense rainfall from the Meghalaya hills generates rapid inundation of low-lying areas.

Modelling the Spatio‐Temporal Effects of Water Level Control in an Agricultural Collector Ditch Network

Irrigation and Drainage, Volume 74, Issue 4, Page 1717-1729, October 2025.
ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...

Coupled Hydrodynamic and Biogeochemical Modeling in the Galician Rías Baixas (NW Iberian Peninsula) Using Delft3D: Model Validation and Performance

Journal of Marine Science and Engineering
Estuaries are dynamic and resource-rich ecosystems renowned for their high productivity and ecological significance. The Rías Baixas, located in the northwest of the Iberian Peninsula, consist of four highly productive estuaries that support the region’s
