“…Glacial lake‐outburst floods or jökulhlaups are cataclysmic drainage events due to the release of water stored in proglacial, subglacial or supraglacial lakes. The largest glacial lake‐outburst events relate to the drainage of ice‐dammed lakes along the margins of continental ice‐sheets (Baker, 1973; Herget, 2005; Carrivick, 2006; Alho et al ., 2010; Carling, 2013; Margold et al ., 2018; Lang et al ., 2019; Panin et al ., 2020). Erosion and deposition by such floods have an enormous geomorphological impact due to the breaching of drainage divides and the re‐routing of drainage systems (Baker, 1973; Mangerud et al ., 2004; Gupta et al ., 2007, 2017; Lang et al ., 2019; Panin et al ., 2020).…”

Upper-flow-regime bedforms, including upper-stage-plane beds, antidunes, chutes-and-pools and cyclic steps, are ubiquitous in glacigenic depositional environments characterized by abundant meltwater discharge and sediment supply. In this study, the depositional record of Froude near-critical and supercritical flows in glacigenic settings is reviewed, and similarities and differences between different depositional environments are discussed. Upper-flow-regime bedforms may occur in subglacial, subaerial and subaqueous environments, recording deposition by free-surface flows and submerged density flows. Although individual bedform types are generally not indicative of any specific depositional environment, some observed trends are similar to those documented in non-glacigenic settings. Important parameters for bedform evolution that differ between depositional environments include flow confinement, bed slope, aggradation rate and grain size. Cyclic-step deposits are more common in confined settings, like channels or incised valleys, or steep slopes of coarse-grained deltas. Antidune deposits prevail in unconfined settings and on more gentle slopes, like glacifluvial fans, sandrich delta slopes or subaqueous (ice-contact) fans. At low aggradation rates, only the basal portions of bedforms are preserved, such as scour fills related to the hydraulic-jump zone of cyclic steps or antidune-wave breaking, which are common in glacifluvial systems and during glacial lake-outburst floods and (related) lake-level falls. Higher aggradation rates result in increased preservation potential, possibly leading to the preservation of complete bedforms. Such conditions are met in sediment-laden j€ okulhlaups and subaqueous proglacial environments characterized by expanding density flows. Coarser-grained sediment leads to steeper bedform profiles and highly scoured facies architectures, while finer-grained deposits display less steep bedform architectures. Such differences are in part related to stronger flows, faster settling of coarse clasts, and more rapid breaking of antidune waves or hydraulic-jump formation over hydraulically rough beds.

“…However, the high haplotype diversity, the low genetic differentiation, the significant differences ( F ST ) and differentiations (ETPD) between the rivers, confirmed also by the relatively high variance between them (AMOVA), leads us to speculate the possibility of an interconnected microrefugia network between the Pannon and the Pontic region, making the species a Ponto-Pannonian element. During the interglacial periods, and after the LGM, the melting of the ice sheets led to more complex hydrological networks (Panin et al ., 2020), which would have allowed the dispersal of individuals from different microrefugia, leading to the interbreeding of the different lineages. The concept of a vast network of microrefugia, with favorable habitat for small invertebrates was also suggested by Sworobowicz et al .…”

Once widespread in the large European rivers, Palingenia longicauda underwent a drastic range contraction as a result of the intense pollution and hydromorphological interventions of the 19th and 20th centuries. For the last decades it was considered to be restricted only to the Tisa River and its tributaries, and to the Rba&aacute River, but new reports indicated its presence in the Danube River in Hungary, in the Danube Delta in Romania and Ukraine, and in the Prut River in the Republic of Moldova. The objective of this study is to analyze the phylogeographic pattern between the two main eco-regions (Pannon and Pontic) of the species distribution, based on the combined mitochondrial COI (472 bp) and 16S (464 bp) sequences generated for individuals collected in Romania and Ukraine, and from publicly available ones, representing the Tisa catchment populations. The presence of viable populations in the Danube Delta and on the Prut River in Romania is confirmed, and additional presence on the Mureș and Bega rivers from Romania, and on the Styr and Horyn rivers in Northern Ukraine is shown. The phylogeographic results indicate that the presence of the analyzed populations are not the result of recent founding events from the Pannon region, confirming the survival and expansion of cryptic local lineages. The recent recovery of the species may be related to the improvement of water quality as a result of the implementation of the EU Water Framework Directive and the EU Floods Directive after 2000.

“…The evolution of hydrologic drainage systems stems from the combined effects of complex system processes ranging from mantle convection, lithospheric‐scale tectonics, and glaciation to surface erosion and sedimentation. These multi‐scale processes can reshape landscapes, alter the habitats of aquatic species, modify hydrological processes, and affect mass transports (Panin et al., 2020; Sharman et al., 2017; Willett et al., 2014). Drainage pattern reorganization is typically a long‐term response from the perturbations in tectonics, lithology, and climatic conditions (Fan et al., 2018).…”

Ongoing Drainage Reorganization Driven by Rapid Lake Growths on the Tibetan Plateau

Drainage reorganization generally occurs on geological time scales under unstable river network conditions. A few local‐scale studies indicate that recent climatic changes might accelerate the drainage reorganization process. However, large‐scale drainage reorganization during the modern era is rarely documented. This study examines ongoing drainage reorganization on the endorheic Tibetan Plateau (TP) as a primary result of drastic lake expansion. A total of 11 drainage system reorganization events comprising 24 different lake basins and covering a total area of 61,115 km2 occurred between 2000 and 2018. Assuming the continued growth rate of TP lakes, we project another 20 basins will be reorganized before 2030. These drainage basin reorganizations not only alter hydrological processes in the endorheic TP but may also cause the endorheic‐exorheic transition, leading to the upstream sprawl of the Yangtze River Basin and posing outburst flooding risks on China's key infrastructure such as the Qinghai‐Tibet Railway.
