Glacial lake outburst floods (GLOFs) have attracted increased research attention recently. In this work, we review GLOF research papers published between 2017 and 2021 and complement the analysis with research community insights gained from the 2021 GLOF conference we organized. The transdisciplinary character of the conference together with broad geographical coverage allowed us to identify progress, trends and challenges in GLOF research and outline future research needs and directions.

This paper reports on a recent glacial lake outburst flood (GLOF) event that occurred on 26 June 2020 in Tibet, China. We find that this event was triggered by a debris landslide from a steep lateral moraine. As the relationship between the long-term evolution of the lake and its likely landslide trigger revealed by a time series of satellite images, this case provides strong evidence that it can be plausibly linked to anthropogenic climate change.

There is increasing interest and need to analyze the contribution of anthropogenic climate change to negative impacts of climate change. We study the case of glacial lake Palcacocha in Peru, which poses a significant flood risk to the city of Huaraz. We found that greenhouse gas emissions; strong urbanization processes without appropriate land use planning; and social, cultural, political, and institutional factors all contribute to the existing flood risk.

In 1941, the glacial lagoon Lake Palcacocha in the Cordillera Blanca (Peru) drained suddenly. The resulting outburst flood/debris flow consumed another lake and had a disastrous impact on the town of Huaraz 23 km downstream. We reconstuct this event through a numerical model to learn about the possibility of prediction of similar processes in the future. Remaining challenges consist of the complex process interactions and the lack of experience due to the rare occurrence of such process chains.

Most mountain glaciers have receded throughout the last century in response to global climate change. This recession produces a range of natural hazards including glacial lake outburst floods (GLOFs). We have produced the first global inventory of GLOFs associated with the failure of moraine dams and show, counterintuitively, that these have reduced in frequency over recent decades. In this paper we explore the reasons for this pattern.

(1) Evaporation under ice-free and sublimation under ice-covered conditions and its influencing factors were first quantified based on 6 years of eddy covariance observations. (2) Night evaporation of Qinghai Lake accounts for more than 40 % of the daily evaporation. (3) Lake ice sublimation reaches 175.22 ± 45.98 mm, accounting for 23 % of the annual evaporation. (4) Wind speed weakening may have resulted in a 7.56 % decrease in lake evaporation during the ice-covered period from 2003 to 2017.

Evaporation from open water is a well-studied problem in hydrology. Robert E. Horton, unknown to most investigators on the subject, studied it in great detail by conducting experiments and relating them to physical laws. His work furthered known theories of lake evaporation but was not recognized. This is unfortunate because it performs better than five variously complex methods across scales (local to continental; 30 min–2 months) and seems quite relevant for climate-change-era problems.

Wild salmon numbers in Nova Scotia, Canada, have been plummeting in recent decades. In 2014, we launched an ionic aluminium monitoring program in Nova Scotia to see if this toxic element was a threat to salmon populations. We found that all 10 monitored rivers had ionic aluminium concentrations that exceeded the threshold for aquatic health. Our results demonstrate that elevated aluminium still threatens aquatic ecosystems and that delays in recovery from acid rain remains a critical issue.

We found that heat transported from Lake Baikal to its ice cover is up to 10 times higher than traditionally assumed and strongly affects the ice melting. The heat is transported by under-ice currents on the background of a strong temperature gradient between the ice base and warmer waters beneath. To parameterize this newly quantified transport mechanism, an original boundary layer model was developed. The results are crucial for understanding seasonal ice dynamics on lakes and marginal seas.

Between 1992 and 2012, concentrations of suspended sediment decreased at about 60 % of 137 US stream sites, with increases at only 17 % of sites. Sediment trends were primarily attributed to changes in land management, but streamflow changes also contributed to these trends at > 50 % of sites. At many sites, decreases in sediment occurred despite small-to-moderate increases in the amount of anthropogenic land use, suggesting sediment reduction activities across the US may be seeing some success.

We present the first annually resolved stable isotope record (1819–1998) from shells of Swedish river mussels. Data reflect hydrological processes in the catchment and changes in the isotope value of local precipitation. The latter is related to the origin of moisture from which precipitation formed (North Atlantic or the Arctic) and governed by large-scale atmospheric circulation patterns. Results help to better understand climate dynamics and constrain ecological changes in river ecosystems.

River network structure is an overlooked feature of catchments. We demonstrate that network structure impacts broad spatial patterns of river characteristics in catchments using regulatory data. River habitat quality increased with network density, but other characteristics responded differently between study catchments. Network density was quantified using a method that can easily be applied to any catchment. We suggest that river network structure should be included in catchment-level studies.

This paper uses a unique observational dataset of a tropical African lake (L. Kivu) to assess the effect of rain on lake surface temperature. Data from 4 years were categorised by daily rain amount and total net radiation to show that heavy rain may reduce the end-of-day lake temperature by about 0.3 K. This is important since lake surface temperature may influence local weather on short timescales, but the effect of rain on lake temperature has been little studied or parametrised previously.

The hyporheic zone is the area below riverbeds where surfacewater and groundwater mix. Hyporheic flow is linked to river processes and functions, but research to date has not sufficiently addressed how factors operating at different scales in time and space drive hyporheic flow variations at reach and larger scales. This review presents the scale-specific processes and interactions that control hyporheic flow, and a case study showing how valley factors affect its expression at the reach scale.

New Zealand is a natural laboratory for investigating water quality responses to land use intensity because it has one of the highest rates of agricultural intensification globally over recent decades. We interpreted water quality state and trends (1989–2014) of 77 river sites across NZ. We show that the greatest long-term negative impacts on river water quality have been increased cattle densities and legacy nutrients from intensively managed grasslands and plantation forests.

An index of floodplain surface complexity is developed in this paper and applied to eight floodplains from different geographic settings. Floodplain width and sediment yield were associated with the index or with sub-indicators, whereas hydrology was not. These findings suggest that valley and sediment conditions are important determinants of floodplain surface complexity, and these should complement hydrology as a focus of floodplain research and management.

Lake droughts result in significant hydrological, ecological and economic consequences. This study proposes approaches for quantifying the lake drought features and estimating the contributions from individual factors, taking China’s largest freshwater lake as a case examination. Our results showed that the recently increased lake droughts were due to hydroclimatic effects, with less important contributions from the water impoundments of the world’s largest dam affecting the lake outflows.

This paper presents evaluation of resistance parameters: friction slope, friction velocity and Manning coefficient in unsteady flow. Theoretical description is facilitated with the analysis of field data from artificial dam-break flood waves in a small lowland watercourse. The methodology to enhance the evaluation of resistance by relations derived from flow equations is proposed. The study shows the Manning coefficient is less sensitive to simplified relations than other parameters.

Historical hydrology combines documentary data with hydrological methods to lengthen flow records to the past centuries. We describe the methodological evolution of historical hydrology under the influence of developments in hydraulics and statistics. Analysis of 45 case studies in Europe show that present flood magnitudes are not unusual in the context of the past, whereas flood frequency has decreased, although some rivers show a reactivation of rare floods over the last two decades.

A quantitative measure for the dependence of a lake on groundwater (G index) introduced in this study revealed generally large groundwater dependency among the lakes. The isotope mass balance approach proved to be especially useful when the groundwater reliance of lakes situated in a relatively small area with similar climatic conditions needs to be determined.

Short summary
This paper proposes a methodology, shaped by the EU Flood Directive, for the integrated assessment of flood risk at the regional scale for multiple receptors (i.e. people, economic activities, natural and semi-natural systems and cultural heritage) based on the subsequent assessment of hazards, exposure and vulnerability. By means of MCDA and GIS tools, it supports the ranking of the area, sub-areas and hotspots at risk, in order to evaluate the benefits of different risk prevention scenarios.
