This opinion paper shows how sociohydrology can better support water management by moving from understanding systems to guiding action. Drawing on ten years of work in the Panta Rhei initiative, it offers a simple way to compare cases, trace how actions lead to intended and unintended outcomes, and improve monitoring, learning, fairness, and legitimacy in decision-making.

When Tropical Cyclone Ditwah struck Sri Lanka in 2025, severe floods and landslides caused widespread harm despite warnings. We examined weather and river records, reservoir storage, warning messages, and experiences of affected communities. The study found that rapidly worsening hazards left too little time for institutions and households to act effectively. It shows why better forecasts must be matched by clearer warnings, faster decisions, and coordinated emergency planning.

Flash floods develop quickly, but the records needed to study them are scattered across many sources. We created TORRENT by linking flood reports, rainfall, river flow, drainage-area information, and field measurements across the contiguous United States. It contains 42 466 reported events and 806 ready-to-use case packages, including 21 carefully checked cases. Its open, machine-readable design will help people and artificial intelligence tools study floods and compare prediction methods.

Understanding the role of soil in the storage of organic carbon is critical for a large number of environmental processes. Current practices rely on the drilling and analysis of samples, which is expensive, time consuming and destructive. Here we present a technique able to map soil organic carbon variability using measurements of the electrical properties of the subsurface without drilling. Our results advance soil management strategies to enhance carbon sequestration and storage.

Rain runs off in two main ways: saturation excess when soil is full, and infiltration excess when rain exceeds infiltration. They often occur simultaneously in a watershed, but most models treat them separately. We introduce a new theory that captures both processes within a single framework, tracking their shift over space and time. Tested over 181 U.S. watersheds, the theory well predicts streamflow in most watersheds and improves understanding of runoff under diverse climates.

In September 2024 an exceptional flood hit the Austrian Danube Basin, the largest in parts of Lower Austria since records began. Using weather and river data, we compare this event with historic floods from 1899, 2002 and 2013. The 2024 flood was driven by a slow-moving rainstorm and saturated soils, causing record flows at smaller rivers. The study shows a shift toward more localized, intense floods, highlighting the need for adaptive flood-risk management in a warming climate.

Study signifies how the use of limited streamflow records with satellite data shows promising approach to improve hydrological predictions in data-sparse regions. Results show combining satellite observations with even a small number of targeted river flow measurements can support reliable hydrologic modeling in data limited catchments. Further, this approach can enhance research dynamics in regions with no or limited observed data availability by using consistent datasets of satellite products.

This study shows that streamflow isotope data in a catchment-scale isotope-based transport model were sufficient to isolate preferential flow in the unsaturated zone but insufficient to isolate the preferential release of young groundwater, as isotope signals were strongly damped by large passive groundwater storage. As a result, groundwater age-selection assumptions affected estimates of long transit times, making it difficult to quantify the fraction of stream water older than 100 days.

Using advances in transit time estimation and tracer data, we tested if fast-flow transit times are controlled solely by soil moisture or if they are also controlled by precipitation intensity. We used soil-moisture-dependent and precipitation-intensity-conditional transfer functions. We showed that a significant portion of event water bypasses the soil matrix through fast flow paths (overland flow, tile drains, preferential-flow paths) in dry soil conditions for both low- and high-intensity precipitation.

We studied how farming practices affect soil and sediment movement in a small Austrian catchment. By monitoring water and sediment during 55 rain events, we found that erosion control worked well in flat fields near the stream, but not in steep or distant fields. Our results show that reducing soil loss requires strategies that consider slope, distance to streams, and how water flows through the landscape.

The Unsolved Problems in Hydrology (UPH) initiative has emphasized the need to establish networks of multi-decadal hydrological observatories to tackle catchment-scale challenges on a global scale. This opinion paper provocatively discusses two endmembers of possible future hydrological observatory (HO) networks for a given hypothesized community budget: a comprehensive set of moderately instrumented observatories or, alternatively, a small number of highly instrumented supersites.

Flood risk assessments help us decide how to reduce the risk of flooding. Since these assessments are based on probabilities, it is hard to check their accuracy by comparing them to past data. We suggest a new way to validate these assessments, making sure they are practical for real-life decisions. This approach looks at both the technical details and the real-world situations where decisions are made. We demonstrate its practicality by applying it to flood emergency planning.

A methodology of regional flood hazard mapping is proposed, based on data in Austria, which combines automatic methods with manual interventions to maximise efficiency and to obtain estimation accuracy similar to that of local studies. Flood discharge records from 781 stations are used to estimate flood hazard patterns of a given return period at a resolution of 2 m over a total stream length of 38 000 km. The hazard maps are used for civil protection, risk awareness and insurance purposes.

Floods often take communities by surprise, as they are often considered virtually
impossibleyet are an ever-present threat similar to the sword suspended over the head of Damocles in the classical Greek anecdote. We discuss four reasons why extremely large floods carry a risk that is often larger than expected. We provide suggestions for managing the risk of megafloods by calling for a creative exploration of hazard scenarios and communicating the unknown corners of the reality of floods.

Undisturbed soil monoliths combine advantages of outdoor and indoor experiments; however, there are often size limitations. A promising approach is the combination of smaller blocks to form a single large monolith. We compared the runoff properties of monoliths cut in half and recombined with uncut blocks. The effect of the combination procedure was negligible compared to the inherent soil heterogeneity, and we conclude that advantages outweigh possible adverse effects.

The study proposes a quantitative model of the willingness to cooperate in the Eastern Nile River basin. Our results suggest that the 2008 food crisis may account for Sudan recovering its willingness to cooperate with Ethiopia. Long-term lack of trust among the riparian countries may have reduced basin-wide cooperation. The model can be used to explore the effects of changes in future dam operations and other management decisions on the emergence of basin cooperation.

There is an unclear understanding of which processes regulate the transport of water, solutes, and pollutants in streams. This is crucial since these processes control water quality in river networks. Compared to other approaches, we obtained clearer insights into the processes controlling solute transport in the investigated reach. This work highlights the risks of using uncertain results for interpreting the processes controlling water movement in streams.

There is serious concern that river floods are increasing. Starting from explanations discussed in public, the article addresses three hypotheses: land-use change, hydraulic structures, and climate change increase floods. This review finds that all three changes have the potential to not only increase floods, but also to reduce them. It is crucial to consider all three factors of change in flood risk management and communicate them to the general public in a nuanced way.

Sound understanding of how floods come about allows for the development of more reliable flood management tools that assist in mitigating their negative impacts. This article reviews river flood generation processes and flow paths across space scales, starting from water movement in the soil pores and moving up to hillslopes, catchments, regions and entire continents. To assist model development, there is a need to learn from observed patterns of flood generation processes at all spatial scales.

The role and impact of using additional data (other than runoff) for the prediction of daily hydrographs in ungauged basins are not well understood. In this study, we assessed the model performance in terms of runoff, soil moisture, and snow cover predictions with the existing regionalization approaches. Results show that the best transfer methods are the similarity and the kriging approaches. The performance of the transfer methods differs between lowland and alpine catchments.

Editorial statement
The paper provides interesting insight about the relative importance of local land use change versus climate change effects on sediment delivery to surface waters at a decadal time scale.
The paper provides interesting insight about the relative importance of local land use change...
Short summary
This study explored the quantitative contribution of agricultural intensification and climate change to the sediment load of a small agricultural watershed. Rather than a change in climatic conditions, changes in the land structure notably altered sediment concentrations under high-flow conditions, thereby contributing most to the increase in annual sediment loads. More consideration of land structure improvement is required when combating the transfer of soil from land to water.
This study explored the quantitative contribution of agricultural intensification and climate...
