Devanshi Pathak (CEH) has her PhD work published in Water Resources Research, title: Hourly Prediction of Phytoplankton Biomass and its Environmental Controls in Lowland Rivers. We have developed a high-resolution river model to predict hourly-scale dynamics of phytoplankton biomass and relevant physico-chemical water quality variables in lowland rivers. The model was tested in the lower River Thames, UK, using hourly to monthly scale observations of a two year period. Through this modelling exercise, we demonstrated that the model satisfactorily predicts the diurnal variability and transport of phytoplankton biomass along the river network, and can serve as a powerful tool both for predictive purposes and for hindcasting past conditions when hourly resolution water quality monitoring was unavailable. We also derived important environmental controls and their optimum ranges that promoted high phytoplankton blooms, and suggested possible management solutions for phytoplankton management in the river. Overall, the hourly model improves biomass prediction and represents a step forward in high‐resolution phytoplankton modelling and consequently, bloom management in lowland river systems.
Diana Derepasko (UFZ) reports her first PhD research paper published in Environmental Modelling & Software is out! This is a review paper on optimization problem decisions and their implications for the spatial and temporal scales that featured a collaboration with Joseph Guillaume (Australian National University) and Avril Horne (Melbourne University), title: Considering scale within optimization procedures for water management decisions: balancing environmental flows and human needs. Here is the graphical abstract:
Lorenzo Pin (NIVA) has a new publication in Molecular Ecology Resources journal, entitled Two different approaches of microbial community structure characterization in riverine epilithic biofilms under multiple stressors conditions: Developing molecular indicators, which reports on a significant correlation between the prokaryotic community composition and pH in rivers from two different geographical areas in Norway. CARD‐FISH and metabarcoding data followed the pattern of the environmental variables, but the main feature distinguishing the community composition was the regional difference itself.
Afua Owusu (IHE) published a paper based on the literature review of her PhD work, entitled Re‐operating dams for environmental flows: From recommendation to practice which covers practical cases of dams being re-operated to release environmental flows. Afua presented it at the 6th Biennial Symposium of the International Society for River Science which was held at the University of Natural Resources and Life Sciences (BOKU) in Vienna, Austria in September 2019. The article is part of a special issue of the conference contributions in the River Research and Applications Journal on the theme of Riverine landscapes as coupled socio-ecological systems.
