A 500 m deep multipurpose research borehole and monitoring station in Delft, the Netherlands

The 500 m deep DAPGEO-02 multifunctional research borehole and monitoring station was drilled in Delft in spring 2022. Dinoflagellate biostratigraphy reveals that the borehole goes through the Neogene Upper North Sea Group, including the Waalre, Maassluis, Oosterhout, Diessen, an...

WQ-ERT: Water Quality Prediction in Low-Resource Domains Using Gaussian Noise-Augmented Transformer Encoder: Case Study in Dili, Timor-Leste

Evaluating water quality is fundamental to ensuring that freshwater ecosystems support the well-being of all life on Earth. The present study uses physicochemical parameters to assess groundwater in Dili, Timor-Leste, from 2011 to 2018. Water quality was determined using the conv...

North Sea Storm Surges Amplified by Oscillations Triggered by Preceding Storms

Abstract Storm surges are often treated as independent extremes, yet extratropical cyclones and associated coastal water‐level extremes frequently occur in clustered sequences. Although clustering can increase flood hazard by shortening recovery time, it remains unclear whether p...

Exploring the added value of assimilating satellite altimeter measurements in a North Sea wave model using the Deterministic Ensemble Kalman Filter

Abstract This study reports on the impact of assimilating satellite altimeter measurements with the Deterministic Ensemble Kalman Filter (DEnKF) using a regional SWAN wave model for the North Sea. We assimilated satellite altimeter measurements over a 3-month period (December 202...

Invited perspectives: Towards usable compound event research

Abstract. Supporting stakeholders with science-based decision-making to mitigate and adapt to climate change impacts is a central mandate of the climate research community. In particular, mapping out scenario-dependent climate risk landscapes is one of the most pressing challenge...

Global hyper-resolution modeling of historical and future groundwater dynamics

Abstract. The sustainable management of global groundwater resources is a key societal challenge and is central to the Sustainable Development Goals. The localized dynamics of groundwater abstraction, topography, and surface-water interactions, as well as the sensitivity of groun...

A Framework for Quantifying Diverse Multi‐Hazard Interactions to Enhance Climate Resilience

ABSTRACT Multi‐hazard events generate impacts exceeding those of individual hazards but remain difficult to assess due to complex interactions. This study presents a generalized framework for analyzing four interaction types—multivariate, preconditioned and triggering, spatially,...

Renewable energy caves: water replenishment holes in offshore monopiles create novel marine habitats

The expansion of offshore renewable energy introduces artificial hard substrate, but the ecological effects may change depending on design features. For example, water replenishment holes, implemented for internal water refreshment and corrosion control, also allow colonisation o...

Investigation of soil arching evolution in piled embankments with three-dimensional trapdoor tests

This study focused on the mobilisation and degradation of three-dimensional soil arching by adopting a matrix trapdoor test device with 144 individually and electrically controlled movable plates to simulate unreinforced piled embankments at different coverage ratios and fill hei...
