Morphogenesis and oxygen dynamics in phototrophic biofilms growing across a gradient of hydraulic conditions

Tom Ian Battin, Hannes Markus Peter, Amin Niayifar, Anna Depetris, Michael Kühl

Biofilms are surface-attached and matrix-enclosed microbial communities that dominate microbial life in numerous ecosystems. Using flumes and automated optical coherence tomography, we studied the morphogenesis of phototrophic biofilms along a gradient of ...

River regulation alters the natural flow regime of streams with consequent impacts on terrestrial and aquatic habitats of the riparian zone. The severity of such impacts can be modulated by changing the redistribution rules at water intakes and reservoirs. ...

Hydrological and hydraulic solutions for the sustainability of habitat life in human altered streams

Amin Niayifar

In this thesis, I aim to contribute to the research towards improving the sustainability of habitat life in streams affected by anthropogenic activities. With the growing trend of altering natural water regimes due to hydropower operations, irrigation, and ...

Modeling Macroroughness Contribution to Fish Habitat Suitability Curves

Paolo Perona, Holly Jayne Oldroyd, Amin Niayifar

Improved water management strategies necessitate a solid understanding of environmental impacts associated with various flow release policies. Habitat suitability models use hydrodynamic simulations to generate weighted usable area curves, which are useful ...

Dynamic water allocation policies improve the global efficiency of storage systems

Paolo Perona, Amin Niayifar

Water impoundment by dams strongly affects the river natural flow regime, its attributes and the related ecosystem biodiversity. Fostering the sustainability of water uses e.g., hydropower systems thus implies searching for innovative operational policies ...

A Software to Optimize Economic and Ecological Efficiency of Small Hydropower Plants

Paolo Perona, Amin Niayifar, Stefania Tron

The software we propose enables users to test several water allocation rules (both static and dynamic) for a specific small hydropower plant and to evaluate them both in term of economic and ecological benefits. For each water allocation rule the energy pr ...

A new analytical model for wind farm power prediction

Fernando Porté Agel, Amin Niayifar

In this study, a new analytical approach is presented and validated to predict wind farm power production. The new model is an extension of the recently proposed by Bastankhah and Porte-Agel for a single wake. It assumes a self-similar Gaussian shape of th ...
