Sub-daily stable water isotope dynamics of urban tree xylem water and ambient vapor
The authors combined in situ monitoring of stable isotopes and ecohydrological monitoring in different urban vegetation in Berlin. They provide novel insights on plant physiology and hydrological functioning through high-resolution isotope data to capture sub-daily plant water uptake and internal water cycling.
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.
Stricter reductions of nutrient pollution support riverine community recovery in degraded catchments
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.
Extreme summer storm elicits shifts in biogeochemistry, primary productivity, and plankton community structure in a large-scale lake enclosure experiment
From Soil to Sediment: Bedform Migration Shapes Microbial Communities From Eroding Bank Soil During Terrestrial–Aquatic Regime Shift
The authors tested the impact of simulated ripple migration on two types of river sediment, namely aquatic sediment and incoming soil from eroding riverbanks, and compared them to stationary conditions in a microcosm experiment. Ripple migration influences community dynamics and microbial metabolism and decelerates the colonization of incoming soil from eroding riverbanks.
Reducing Uncertainty in Hydrologic Model Using Water Isotope and Chloride Data for Glacierized Catchment on the Tibetan Plateau
The Role of Beaver Dams in Modulating Hydrological Connectivity and Nutrient Dynamics in Agricultural Catchments With Intermittent Streams
Beaver dams and associated wetlands can alter hydrological connectivity and biogeochemical processes,, but their combined influence on nutrient dynamics remains understudied. The authors investigated the effects of a network of beaver-impacted waters on macronutrients dynamics in an intermittent stream network showing the effectiveness of beaver created wetlands as nature-based solutions.
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. .
