The utilization of Underground Pumped Storage Power Systems (UPSP) addresses the growing need for energy storage in face increasing intermittent sources. Simultaneously, closure mining activities has resulted vast underground spaces potentially becoming available alternative purposes. This paper explores potential repurposing abandoned mines, particularly coal as lower reservoirs UPSPs. challenges associated with employing mines are multifaceted. foremost challenge stems from limited...
Disaster resilience and building back better (BBB) are key concepts in the disaster risk discourse, however, these often remain vague for many stakeholders involved recovery. Based on reconstruction process Germany after extreme floods of 2021 with more than 180 deaths, we explore challenges opportunities to strengthen resilient recovery one world's wealthiest most technologically advanced countries. We examine factors that contributed severe losses damages assess different phases process....
Abstract Background Because of global climate change, extreme flood events are expected to increase in quantity and intensity the upcoming decades. In catchments affected by ore mining, flooding leads deposition fine sediments enriched trace metal(loid)s. Depending on their concentration, metal(loid)s can be a health hazard. Therefore, exposure local population sediments, either ingestion (covering direct consuming food grown these sediments) or via inhalation dried contributing atmospheric...
Abstract During the flood event in 2021 within Western Europe, many bridges were severely damaged, particularly North Rhine‐Westphalia and Rhineland‐Palatinate Germany. Within this study, a statistical analysis of damages caused to by was carried out. First, locations along rivers Inde, Vicht Ahr mapped. Based on these data, correlations among damage patterns analyzed. Approximately 25 both Inde while over 80 damaged. Notably, located near residential areas suffered more severe than those...
ABSTRACT The July 2021 flood event severely affected western Germany, particularly Rhineland‐Palatinate and North Rhine‐Westphalia, with rainfall intensity water levels exceeding the 100‐year return period in many areas. This study analyzes performance of monitoring forecasting systems during this extreme event, focusing on integration meteorological hydrological data within detection, monitoring, processes. findings reveal critical challenges translating information into actionable...
A new type of small, dry-filled geotextile tubes is introduced, that, in a stacked formation, can be used as dike cores. Dikes made out these consist great potential regarding more resilient flood protection. The protects the fill from erosion, enabling steeper slopes along with reduced material and less land consumption. behavior failure mechanisms such dikes were investigated first by literature research second full-scale hydraulic model tests under systematic variation tube number, number...
Surface bypasses are downstream migration structures that can help reduce hydropower-induced damage to migrating fish. However, no comprehensive design concept facilitates good surface bypass performance for a wide range of sites and species is available. This why fish-passage efficiencies at recently built vary widely between 0% up 97%. We reviewed 50 studies existing guidelines salmonids, eels potamodromous identify crucial criteria employed in North America, Europe Australia. Two-tailed...

Abstract Increasing extreme weather events pose significant challenges in hydrology, requiring tools for preparedness and prediction of intense rainfall impacts, especially flash floods. Current risk reduction measures pluvial flood management rely on hazard maps, but inconsistencies transregional standards that are used assessment hinder cross-regional comparisons. While there existing guidelines the development is still a lack holistic modelling systems enable harmonised predictions...
Recent heavy rainfall-induced flood events, for example in Germany, Australia and USA, have highlighted the relevance of countermeasures saving human lives preventing property damage. Newly introduced ML-based forecasting methods rely on high-intensity synthetic rainfall events due to sparsity their real counterpart. Such data instances can be produced by precipitation generators trained an adversarial setting historical data. Capturing processes are often highly distributed, with multiple...
Passage through hydropower plants can cause severe injuries for downstream migrating fish. Bar racks and bypass systems help to protect fish from turbine-induced mortality if they are designed correctly following guidelines. Currently, it is not possible assess how effective bar that do meet design criteria protection. We introduced the screening effect as a performance parameter developed an equation determining of silver eels based on empirical approach. compared with results behavioural...
This paper presents a dataset documenting 71 floating debris accumulations at bridges following an extreme hydrological event that hit Belgium and Germany in July 2021. Data were collected from various sources including public authorities' documents, online databases, post pictures field visits. The covers geometry, flood conditions accumulation. In particular, it systematically details dimensions quantifies components, which contain significant portion of anthropogenic objects, addition to...
In the summer of 2021, devastating river floods occurred in Western Europe as a result extreme rainfall. At numerous bridges, debris accumulations were observed, exacerbating flooding upstream by impeding waterflow and sometimes contributing to bridge failure. Due widespread building damage settlements along rivers, these differed markedly from classic logjams, with substantial amounts man-made objects. A new database clogged bridges Belgium Germany – described separate data descriptor was...
Abstract Für den Schutz abwandernder Fische vor einer schädlichen Turbinenpassage können Rechen‐Bypass‐Systeme eine wirksame Maßnahme sein. Um möglichst viele auf ihrer abwärtsgerichteten Wanderung durch ein solches System zu schützen, sollten die Verhaltensweisen der bei Bemessung des Systems Berücksichtigung finden. In ethohydraulischen Untersuchungen mit Aalen, Äschen, Flussbarschen, Lachssmolts und Rotaugen wurden geometrische hydraulische Parameter eines Vertikalrechens getestet, um...
