Groundwater drought is characterized by delayed responses, long duration, and slow recovery, and its evolution is influenced by both local hydroclimatic processes and large-scale ocean–atmosphere variability. To investigate the spatiotemporal e...
This study was conducted in the Upper Olifants River Catchment, located in the Mpumalanga Province of South Africa. The area faces groundwater pollution associated with the current land use and land cover. The primary aim of the present study is to a...
Machine learning (ML) models utilizing high-frequency Internet of Things (IoT) monitoring data offer significant potential for stream-level nowcasting. The assessment of model performance is often a challenging task because conventional approaches ar...
Flood early warning systems (FEWSs) in data-scarce and rapidly responding catchments require monitoring networks that provide sufficient forecasting information with minimal operational cost. This study evaluates the applicability of a data-driven se...
Intensified climate change and anthropogenic activities have increased the complexity and nonlinearity of watershed runoff, challenging accurate runoff simulation and input-factor importance analysis. Physical hydrological models are constrained by p...
Physical clogging during managed aquifer recharge can reduce aquifer conductivity and alter leakage across intervening aquitards. This study presents a quasi-three-dimensional model coupling horizontal groundwater flow, suspended-particle transport,...
The long-term environmental legacy of historical gold mining continues to pose significant concerns about water quality and human health. This study evaluates and compares the impacts of former gold mines on groundwater (GW) and surface water (SW) qu...
Uncertainty in soil hydraulic properties is a major source of hydrological and flood-modeling error, especially in data-scarce, heterogeneous arid soils. In ephemeral stream watersheds, infiltration strongly controls runoff generation and flash-flood...
Long-term structural connectivity in highly regulated plain river networks remains insufficiently understood, particularly under concurrent climatic variability and land-use change. This study examined surface-water structural connectivity in Jiashan...
Historical groundwater databases may contain systematic errors involving ground elevations, spatial coordinates, or hydraulic head measurements, which can affect hydrogeological interpretation and downstream analyses. Conventional outlier detection m...
The Japanese Garden of La Paz, Bolivia, is a sociocultural space with high biodiversity, with its lagoon receiving treated effluent from the “Las Cholas” Wastewater Treatment Unit. Preliminary monitoring revealed elevated organic matter c...
Flood seasonality strongly influences flood risk and its management worldwide. Anthropogenic climate change and land-surface human activities are widely recognized as the two major drivers of its evolution, yet their relative contributions remain poo...
This study takes the pumped hydro storage (PHS) in arid areas—where the irrigation reservoir in the piedmont plain serves as the lower reservoir—as the research object. It establishes a model framework for the evolution of heat flux in th...
Flood susceptibility mapping in large transboundary basins is often constrained by sparse observations, heterogeneous environmental conditions, and validation strategies that overstate model skill when spatial dependence is ignored. This study develo...
Accurate multi-step streamflow forecasting requires models to preserve antecedent streamflow memory and account for delayed dependence between gauges. This study proposes a prior-informed directed-lag graph neural residual model, termed PI-DLGNR. The...
The western desert of Iraq is one of the most water-stressed environments in the Middle East. Characterized by unpredictable rainfall and long periods of evaporation. Several small earth dams have been constructed in this region, which are the only a...
Lumped hydrological modeling approaches based on the Rational Method (RM) continue to be used in engineering practice despite the advent of various sophisticated hydrological modeling tools in the past decades. While the simplicity, low data requirem...
This study proposes a probabilistic methodology to estimate drought hydrographs from observed discharge data recorded at a river gauging station under natural hydrological conditions and under reservoir operation for hydropower generation, with data...
Water flow through saturated and unsaturated porous media underlies groundwater assessment, contaminant transport, agricultural drainage and dam-seepage analysis, yet existing reviews typically address only one link in this chain: a single governing...
Dissolved organic matter (DOM) in coastal rivers plays a key role in land–ocean carbon cycling, yet its spatiotemporal dynamics drivers remain poorly understood. This study investigated five typical rivers across the Bohai Rim, China, using ult...
Transboundary river basins in Central Asia are exposed to interacting reductions in available inflow, increasing water demand and infrastructure losses. This study develops a poly-shock sentinel-node framework for the scenario-based assessment of wat...
