Hydropower development in the Republic of Georgia and implications for freshwater biodiversity conservation

The Caucasus region is a meeting point for culture and nature, lying at the nexus of Europe, the Middle East, Central Asia, and Africa, and identified as one of 36 global biodiversity hotspots. The Republic of Georgia, the center of the Caucasus biodiversity hotspot, encompasses a geographically diverse landscape inhabited by a remarkable,...

Assessment of climate change effects on navigable conditions on the river branches of the Rhine in The Netherlands.

Inland Water Transport (IWT) is one of the modalities for freight transport between the ports of Rotterdam, Amsterdam, Antwerp and the hinterland in Germany. Transport over water between these areas is possible as a result of the presence of the Rhine, but more important are the navigation conditions on the river. As a result of climate change,...

Riverine plastic litter monitoring using Unmanned Aerial Vehicles (UAVs)

Plastic debris has become an abundant pollutant in marine, coastal and riverine environments, posing a large threat to aquatic life. Effective measures to mitigate and prevent marine plastic pollution require a thorough understanding of its origin and eventual fate. Several models have estimated that land-based sources are the main source of...

Accuracy and efficiency in numerical river modelling: Investigating the large effects of seemingly small numerical choices

A river engineer is challenged with the task of setting up an appropriate model for a certain application. The model needs to provide suitable answers to the questions asked (i.e. be effective) and needs to do this within the available time (i.e. be efficient). To set up such a model with sufficient accuracy and certainty, a modeller needs to...

A 30 m Resolution Surface Water Mask Including Estimation of Positional and Thematic Differences Using Landsat 8, SRTM and OpenStreetMap: A Case Study in the Murray-Darling Basin, Australia

Accurate maps of surface water are essential for many environmental applications. Surface water maps can be generated by combining measurements from multiple sources. Precise estimation of surface water using satellite imagery remains a challenging task due to the sensor limitations, complex land cover, topography, and atmospheric conditions....
