Altered near-bed turbulence: insights and negative impacts of inland navigation on benthic habitatsNARA Subscribed
Aquatic ecosystems in rivers are currently exposed to a large number of stressors, causing a massive decline in abundance and biodiversity. One of these impacts is the wave action induced by inland navigation on riverbanks. The wave impact causes increased remobilization and erosion of the bed substrate and thus a recurring disturbance of the benthic habitats. The focus of this study on impacts of ship waves was on altered nea...
In September 2024, a thousand-year flood event of the Wien River was recorded in the Austrian capital Vienna with 450 m 3 s − 1 peak discharge. The flood flows had to cross the city from West to East before discharging into the Danube side-channel. The water stages were close to flood the subway system in some critical parts of the city. However, major inundations in town could be prevented also by the technical control of the...
When professionals assess tree risk, they must consider the potential consequences associated with a branch or whole tree striking a person, vehicle, or structure. This process requires an assessor to determine the diameter and fall distance of a tree part and then gauge the likely damage to a target if failure occurred. The ability to accurately estimate diameter and fall distances is important, as direct measurements are not...
In 2019, the EPMA celebrated its 10th anniversary at the 5th World Congress in Pilsen, Czech Republic. The history of the International Professional Network dedicated to Predictive, Preventive and Personalised Medicine (PPPM / 3PM) is rich in achievements. Facing the coronavirus COVID-19 pandemic it is getting evident globally that the predictive approach, targeted prevention and personalisation of medical services is the opti...
A conceptual model for unbiased calculations of invertebrate abundances from freeze core samplesNARA Subscribed
Freeze coring is a commonly used method for the investigation of the bed sediment fauna of rivers. It is considered to produce quantitative numbers of invertebrate abundance in different depth layers. Calculations of abundance use total volume of the freeze core sample as spatial reference. This definition of sample volume is incorrect. In the present, study freeze core samples are shown to consist of two parts: (1) a cylindri...
The presented study investigates the evolution of artificial gravel placements for Atlantic salmon and sea trout in Aurlandselva in Western Norway. Various monitoring methods have been applied including (i) quantifying the spatial extent and dynamics of spawning sites over the monitoring period, (ii) grain size distributions as well as (iii) applying numerical hydraulic and sediment transport modelling with the aim to test the...
