A tiered complexity conceptual framework for treating water soluble, hydrophilic contaminants in green stormwater infrastructure
Blue-green infrastructure is a critical tool for improving stormwater quality, but the removal of dissolved, hydrophilic contaminants remains a major challenge. The authors propose a tiered conceptual framework of progressively more complex, costly, and resource-intensive interventions to remove dissolved, hydrophilic contaminants and thus minimize risks to ecosystems and drinking water sources.
Hydrological Processes in Lowlands and Plains
Lowlands and plains provide important ecosystem services such as agricultural and forestry production, groundwater recharge, streamflow generation and drinking water supply. This Special Issue collects scientific papers advancing understanding of the mechanisms underlying the movement and storage of water in lowland and plain environments.

Reducing Uncertainty in Hydrologic Model Using Water Isotope and Chloride Data for Glacierized Catchment on the Tibetan Plateau
Knots in the Strings: Do Small-Scale River Features Shape Catchment-Scale Fluxes?
The authors review how river “knots” associated with bifurcations, confluences, and obstructions, which are spatially and temporally heterogeneous reaches in a river network affect reach-scale processes including flow attenuation, enhanced vertical and lateral connectivity, and augmented solute retention and uptake. .

Stepwise tracer-based hydrograph separation to quantify contributions of multiple sources of streamflow in a large glacierized catchment over the Tibetan Plateau
The authors identified the sources of streamflow and their temporal dynamics in a glacierized catchment of the Tibetan Plateau using isotopic and geochemical signatures. They demonstrated that incorporation of high-resolution tracer data in an appropriate model structure can help resolve streamflow components and identify the dynamics of dominant recharge sources in cryosphere environments.

Consequences of the Aral Sea restoration for its present physical state: temperature, mixing, and oxygen regime
The Aral Sea is both an example of large-scale environmental degradation caused by human activity and a message of hope through its partial restoration. The field observations and model scenarios show that the restored part of the Aral Sea appears to be healthy in terms of vertical mixing and oxygenation, but small changes of water level or transparency could alter the entire ecosystem.
Urban Hydrological Connectivity and Response Patterns Across Timescales: An Integrated Time-Frequency Domain Analysis
The authors investigated the interconnections of rainfall, groundwater and stream flow in the Wuhle river in Berlin using autocorrelation, cross-correlation and time-frequency analyses of long-term data. Despite the strong influence of urban storm drainage, they showed a high degree of persistence of the groundwater signals.
