Floods continue to be a wicked problem that require developing early warning system with plausible assumptions of risk behaviour, with more targeted conversation with the community-at-risk. Through this paper we advocate the use of a SMART-approach to encourage bottom-up initiatives to develop inclusive and purposeful early warning systems that benefit the community-at-risk by engaging them at every step of the way along with including other stakeholders at multiple-scales of operations.

SOIL, 8, 133–147,Short summary
The Andes region is prone to natural hazards due to its steep topography and climatic variability. Anthropogenic activities further exacerbate environmental hazards and risks. This systematic review synthesizes the knowledge on the effectiveness of nature-based solutions. Conservation of natural vegetation and implementation of soil and water conservation measures had significant and positive effects on soil erosion mitigation and topsoil organic carbon concentrations.

Soil moisture and groundwater play a significant role in the hydrology of the critical zone in the Earth system, specifically in an agriculture-driven environment. We present here the space-time dynamics of both these components from a well-instrumented critical zone observatory in the Ganga basin, India. Influences on the spatiotemporal variability along with the optimal sampling strategies are explored in this study, providing an insight to the stakeholders for efficient water management.

The R programming language has become an important tool for many applications in hydrology. In this study, we provide an analysis of some of the R tools providing hydrological models. In total, two aspects are uniformly investigated, namely the conceptualisation of the models and the practicality of their implementation for end-users. These comparisons aim at easing the choice of R tools for users and at improving their usability for hydrology modelling to support more transferable research.

This study demonstrates an innovative methodology to estimate the formative discharge of alluvial rivers from remote sensing images. We have developed an automated algorithm in Python 3 to extract the width of a river channel from satellite images. Finally, this channel width is translated into discharge using a semi-empirical regime equation developed from field measurements and threshold channel theory that explains the first-order geometry of alluvial channels.

In this study, we carried out a comparative evaluation of water yield using two approaches, the Lumped Zhang model and the pixel-based approach. Even in pixel-level computations, experiments are made with existing models of some of the involved parameters. The study indicates not only the suitability of pixel-based computations but also clarifies the suitable model of some of the parameters to be used with pixel-based computations to obtain better results.

Geospatial technologies and OIP are promising tools to study the effect of demographic changes and LULC transformations on the spatiotemporal variations in the water quality (WQ) across a large river basin. Therefore, this study could help to assess and solve local and regional WQ-related problems over a river basin. It may help the policy makers and planners to understand the status of water pollution so that suitable strategies could be planned for sustainable development in a river basin.

Several rivers basins in the Ganga plains suffer from very high sediment production in their catchment and there are no good estimates of sediment yield from these basins due to a lack of gauge data. The RUSLE model offers an alternative approach and the same has been applied in a small basin in the Ganga plains. The study demonstrated the usefulness of the proposed methodology for quantifying uncertainty in soil erosion and sediment yield estimates at ungauged basins.

This work quantifies how future land-use and climate change may affect the hydrology of the Upper Ganges basin. Three sets of modelling experiments are run for the period 2000–2035, considering (1) only climate change, (2) only land-use change and (3) both climate and land-use change. Results point towards a severe increase in high flows. The changes are greater in the combined land-use and climate change experiment. We also show that future winter water demands in the region may not be met.

The paper aims to propose a conceptual framework that supports nuanced understanding and analytical assessment of resilience in socio-hydrological contexts. We identify three framings of resilience for different human–water couplings, which have distinct application fields and are used for different water management challenges. To assess and improve socio-hydrological resilience in each type, we introduce a
resilience canvasas a heuristic tool to design bespoke management strategies.

In many agrarian countries (like India), the agricultural practices are usually rainfall dependent. Therefore keeping the water budget into account, precipitation being an important component must be analysed thoroughly for its occurrence and amount. The analysis of trends can provide an insight in understanding the possible impacts in future, which can assist living beings to adapt and cope up with changing climate and hydrological cycle.

The absence of flow data to calibrate hydrologic models may reduce the ability of such models to reliably inform water resources management. To address this limitation, it is common to condition hydrological model parameters on regionalized signatures. In this study, we justify the inclusion of larger sets of signatures in the regionalization procedure if their error correlations are formally accounted for and thus enable a more complete use of all available information.

The contribution of lulcc is to provide a free and open-source framework for land use change modelling. The software, which is provided as an R package, addresses problems associated with the current paradigm of closed-source, specialised land use change modelling software which disrupt the scientific process. It is an attempt to move the discipline towards open and transparent science and to ensure land use change models are accessible to scientists working across the geosciences.

This study mainly focused on the comparison between braided river channels and meandering river channels. We show that the morphology of braided and meandering channels are comparable and their width, depth and slope scale in same way against water discharge. This is the key finding of our study and it has never been tested before.

The Belgian city of Spa is known worldwide for its ferruginous and naturally sparkling groundwater springs that gave their name to the bathing tradition commonly called
spa. However, the origin of the dissolved CO2 they contain was still a matter of debate. Thanks to new analysis on groundwater samples, particularly carbon and helium isotopes together with dissolved gases, this study has demonstrated that the volcanic origin of the CO2 is presumably from the neighboring Eifel volcanic fields.

A methodology is developed for a new hydraulic characterization of continental hydrological basins. For this purpose, the division of wells into flow stretches with different hydraulic behaviour is made according to the results of the flowmeter, supposing that the hypothesis hydraulic heads of the deepest flow stretches of the well do not necessarily match the head shown by the overall well.

The quality control and optimization of soil aquifer treatment (SAT) performance is challenging due to the multiple factors and costs involved. We installed in situ subsurface monitoring sensors that provided continuous high-resolution monitoring of the biochemical and physical conditions of an active SAT system. Data analysis facilitated the determination of the optimal drying and wetting stages, which are critical for suitable SAT management.

Data support is crucial for the research of conflict and cooperation on transboundary rivers. Conventional, manual constructions of datasets cannot meet the requirements for fast updates in the big data era. This study brings up a revised methodological framework, based on the conventional method, and a toolkit for the news media dataset tracking of conflict and cooperation dynamics on transboundary rivers. A dataset with good tradeoffs between data relevance and coverage is generated.

Sand dams capture and store water for use during the dry season in rural communities. A year long field study of three sand dams in Tanzania showed that sand dams are not a suitable habitat for aquatic insects. They capture plenty of water, but most is evaporated during the first few months of the dry season. Sand dams positively impact vegetation and minimally impact erosion. Community water security can be increased by sand dams, but site characteristics and construction are important factors.

The impact of city trees for intercepting rainfall is quantified using measurements and modeling tools. The measurements show that an important amount of rainfall is intercepted, limiting the amount of water reaching the ground. Models are used to extrapolate the measurement results. The performance of two specialized interception models and one water balance model is evaluated. Our results show that the performance of the water balance model is similar to the specialized interception models.

This research examines what processes drive the location and strength of groundwater springs within a peatland environment. Using temperature and geophysical methods, we demonstrate that the relationship between regional groundwater flow gradients and the basin shape below the peatland surface control where groundwater springs occur. Understanding this relationship will support effective restoration efforts, as groundwater spring locations are important to overall peatland function and ecology.

The unprecedented availability of user-generated data on the Web is opening new opportunities for enhancing real-time monitoring and modeling of environmental systems based on data that are public, low-cost, and spatiotemporally dense. In this paper, we contribute a novel crowdsourcing procedure for extracting snow-related information from public web images. The value of the obtained virtual snow indexes is assessed for a real-world water management problem.

Games are an optimal way to teach about water resource sharing, as they allow real-world scenarios to be explored. We look at how games can be used to teach about water resource sharing, by both playing and developing water games. An evaluation of the web-based game Irrigania found Irrigania to be an effective and easy tool to incorporate into curriculum, and a course on developing water games encouraged students to think about water resource sharing in a more critical and insightful way.

The paper includes a review of the current state of high-frequency monitoring in groundwater and surface waters as an outcome of a special issue of HESS and four sessions at EGU on this topic. The focus of the paper is to look at how high-frequency monitoring can be used as a valuable support to assess the management efforts under various EU directives. We conclude that we in future will see a transition from research to implementation in operational monitoring use of high-frequency sensors.

Rangelands, from grasslands to woodlands, cover much of the earth. These areas face great pressure to meet growing water needs. Data on large-scale dynamics that drive water planning remain rare. Our watershed-scale results challenge simplistic hydrological assumptions. Streamflow was resilient to dramatic landscape changes. These changes did shape sediment yield, affecting water storage. Understanding these processes is vital to projections of rangeland water resources in a changing world.

Controlled drainage has been recognized as an effective option to optimize soil moisture conditions for agriculture and to reduce unnecessary losses of fresh water and nutrients. For a grassland field in the Netherlands, we measured the changes in the field water and solute balance after introducing controlled drainage. We concluded that controlled drainage reduced the drain discharge and increased the groundwater storage in the field, but did not have clear positive effects for water quality.

Based on low-altitude aerial infrared surveys, around 370 groundwater–surface water interaction sites were located. Longitudinal temperature patterns, stable isotopes and dissolved silica composition of the studied rivers differed. Interaction sites identified in the proximity of 12 municipal water plants during low-flow seasons should be considered as potential risk areas during flood periods and should be taken under consideration in river basin management under changing climatic situations.

We studied long-term daily records of rainfall and streamflow of the Incomati River basin in southern Africa. We used statistical analysis and the Indicators of Hydrologic Alteration tool to describe the spatial and temporal variability flow regime. We found significant declining trends in October flows, and low flow indicators; however, no significant trend was found in rainfall. Land use and flow regulation are larger drivers of temporal changes in streamflow than climatic forces in the basin.

High-resolution phosphorus and flow data were used to gauge the effects of diffuse (soil P) and point source (septic tank system) mitigation measures in two flashy headwater river catchments. Over 4 years the data indicated an overall increase in P concentration in defined high flow ranges and low flow P concentration showed little change. The work indicates fractured responses to catchment management advice and mitigation which were also affected by variations in seasonal hydrometeorology.

The mitigation of excess nitrogen and phosphorus in river waters requires costly measures. Therefore it is essential to use reliable monitoring methods to select adequate mitigation strategies. Here we show that more development is needed before passive samplers can be considered as reliable alternative for sampling nutrients in stream. We also showed that although continuous sampling is expensive, its reliability precludes unnecessarily high implementation costs of mitigation measures.
