The partition dynamics of organic micropollutants between water and suspended particulate matter in riverine ecosystems differs between dry and wet weather. Chemical concentrations and mixture effects in extracts from rivers are dominated by suspended particulate matter during rain, but the dissolved phase dominates during dry weather.

The authors monitored  water quality parameters over 3 years in an intermittent stream network in the eutrophic, lowland Demnitzer Millcreek catchment, Germany. They focused on the effects of wetland systems impacted by beaver dams on the diurnal, seasonal and inter-annual variation in water quality dynamics and modelled stream metabolism. 

The authors investigated the role of hydrological connectivity dynamics on biogeochemistry in the Oder river-floodplain system through a multi-proxy approach to quantify water sources and ages, evaporation losses, water quality, surface water connectivity via remote sensing and sub-surface connectivity via geophysical surveys. This is important to sustain vulnerable wetlands. 

Dimensionality of parameters and objectives has been increasing due to the accelerating development of models and monitoring networks resulting in major challenges for model calibration. The study highlights limitations of high-dimensional calibration approaches, the role of data uncertainty and deficiencies in model structure of process-based ecohydrological models.

Stable water isotopes are well known tracers of the hydrological cycle producing critical climate science but they are not explicitly included in influential climate reports except for paleoclimate reconstructions. The authors argue that it is time to incorporate isotopes and isotope-enabled modelling into mainstream hydroclimatic forecasting to improve climate change predictions and evidence.

The authors suggest to combine conventional civil engineering methods, nature-based solutions, and biodiversity conservation actions at catchment-scale to leverage flood and drought mitigation and cater to improved biodiversity conservation and human wellbeing. We outline the needs in terms of legislation structure, adequate funding and governance structures to make this happen.
