Enhancing process interpretation with isotopes: potential discharge-isotope trade-offs in ecohydrological modelling of heavily managed lowland catchments
The authors enhanced a tracer-aided hydrological model to help constrain estimates of ecohydrological partitioning and water balance compartments in sub-catchments of the Middle Spree catchment. They disentangled ecohydrological funtioning in this ET dominated region despite the complexity of the heterogeneous landuse, extensive hydraulic infrastructure and long legacy of intensive management.
Target and Nontarget Analyses Reveal Similar Dissolved Organic Contaminant Patterns Relative to Quantified Catchment Characteristics along Two German Rivers
Dense stands of aquatic plants retain water in lowland rivers and in adjacent floodplain aquifers
Since the 1980s mean discharge has declined by around 50% and - without aquatic vegetation – also the water level. Dense stands of aquatic plants have kept the water level high in recent summers despite lowered discharge. Most water was retained in adjacent floodplain aquifers rather than in the river channel.
Low contribution of oxic methane production in shallow productive lakes
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.
