Exploring the Transferability of Image-based algorithms for River Plastic Detection: The Value of Small Mix Datasets

This study demonstrates that using a small, diverse Mix dataset (999 images) improves transferability, reduces costs, and optimizes floating macroplastic detection with YOLOv7 and YOLOv8, highlighting that dataset quality and heterogeneity are critical for global-scale detection.

Direct impact of climate change on groundwater levels in the Iberian Peninsula

The Iberian Peninsula is a water-scarce region that is increasingly reliant on groundwater. Climate change is
expected to exacerbate this situation due to projected irregular precipitation patterns and frequent droughts.
This scientific article utilised convolutional neural networks (CNNs) to assess the direct effect of climate change on groundwater levels, using monthly meteorological data and historical groundwater levels from 3,829 wells.

Grundwasserbeobachtungen über mehrere Dekaden zeigen überraschend stabile Werte in Südwesteuropa

A multi-decadal groundwater level data analysis to evaluate long-term trends and drivers of groundwater levels, using 60 years of data from Portugal, Spain, France, and Italy, and showing the critical need for systematic groundwater monitoring and sustainable management to face water scarcity challenges. This article originally published in English was translated in German in the February 2025 issue of Korrespondenz Wasserwirtschaft on the DWA website.

Data-driven modelling of hydraulic-head time series: results and lessons learned from the 2022 Groundwater Time Series Modelling Challenge

This paper presents the results of the 2022 Groundwater Time Series Modelling Challenge, where 15 teams from different institutes applied various data-driven models to simulate hydraulic-head time series at four monitoring wells. Three of the wells were located in Europe and one was located in the USA in different hydrogeological settings in temperate, continental, or subarctic climates.
