"Methods to determine roughness and surface structures in alluvial streams and engineered waterways"

The roughness of alluvial streams and engineered waterways plays a key role in hydraulic and environmental engineering applications as it determines flow properties such as flow velocity distribution, mean velocities, flow rate, and turbulence characteristics. Roughness has been in the focus of research for a long time and, despite significant advances, this topic still represents a challenge for modern hydraulic engineers dealing with flows over spatially heterogeneous beds. In fact, there is still a lack of knowledge on how the hydraulic effect of roughness can be related to bed topography characteristics. This talk addresses this issue by reviewing recent methodological and technical advances allowing for both the determination of roughness characteristics by considering rough beds as a random field of surface elevations and the analysis of the spatially heterogeneous flow field by the application of the Double-Averaging Methodology (DAM). Scientific and practical examples will be used to highlight the advances, to indicate future research areas, and to show the potential of these approaches to tackle practical issues.

"The 'Dirty Secrets' of Reservoirs"

Multi-purpose reservoirs play an important role in satisfying demands for water supply, irrigation, hydropower, drinking water, flood protection, recreation, navigation, and other purposes. At the same time, they can often have considerable negative impacts on the environment and local biodiversity that remain largely unseen. These “dirty secrets” include sediment deposition, cyanobacteria blooms, and greenhouse gas emissions. Lecture of Prof. Silke Wieprecht touches upon the mentioned problems and aims at discussing the challenges of optimal reservoir management strategies.

Do you use social media to communicate science? Can you make best use of them? This short talk by Gianluca Pescaroli aims at answering these question, and helping you diving the social media to increase the impact of your research.

Water's next: novel insights from young water scientists [Invited Session]

More

Chairs: Mateusz Grygoruk, Michael Nones

IAHR seeks to create opportunities for early-stage scientists to present their research and experiences in science. We believe that the ability to talk about your work with similarly inclined people is crucial for self-development. Trying to address this, we decided to organize a live session devoted to PhD students and young scientists to share their research, discussing actual challenges and future steps. We intend to get informed about and promote novel approaches used by young researchers to tackle classic research questions. We wish to encourage the society of young hydrologists by presenting cutting-edge findings developed by young researchers at the edge of hydrology and related engineering and environmental sciences. We invite you to join the session to see what’s next in water research.

Partick Meire "Is ecosystem based adaptation the answer to the challenges of climate change in estuarine and coastal systems?" [Keynote] followed by a discussion on "Nature Based Solutions in coastal areas"

More

Chairs: Jan Marcin Węsławski, Paweł Rowiński, Tomasz Okruszko

Coastal areas are among the most productive habitats and home to a large part of the world population. As a consequence they are heavily impact and severely threatened by climate change. It is clear that past management options are not fit for the future challenges and a change towards a more ecosystem based approach using nature based solutions is urgently needed. In this talk I will describe an integrated ecosystem based management of the Schelde estuary and extend this to a wider vision on managing coastal systems.

Panelists:

  • Marc Huygens - Environmental Manager within the DEME group
  • Jan Marcin Węsławski - Director of Institute of Oceanology PAN and the professor in marine ecology

Rivers are vital ecosystems providing a multitude of ecosystem services that are vital for human societies. Moreover, rivers have high strategic importance for global ecological functions and biodiversity. As many large rivers in the world, the Danube River is a highly complex socio-ecological system and a hotspot of biodiversity and ecosystem services, especially considering the floodplain systems, but is also affected by multiple human activities like navigation, hydropower, urban development or agriculture, making river-floodplain systems to one of the most threatened ecosystems worldwide. Conservation and restoration of ecosystem functions and service provisioning is an urgent task, but challenging because of the diversity of human activities and policy targets, scarcity of data compared to the complexity of the systems, heterogeneity of environmental problems, and differences socio-economic conditions along the Danube. Therefore, in this presentation we provide an overview on the status of floodplains and their strategic importance at the whole river network scales and present examples how combined assessment approaches for biodiversity and ecosystem services could support restoration planning and the effect of implemented restoration measures on these floodplain properties. In the future, emerging issues such as climate change and invasive non-native species will need careful consideration in the ecosystem management of floodplains to minimize unintended effects.

10.00 - 11.30
Ian Guymer "Longitudinal Dispersion – Exploring Limitations of Taylor" [Keynote]

More

Chairs: Paweł Rowiński, Tomasz Okruszko

The management of water quality in rivers, urban drainage and water supply networks is essential for ecological and human well-being. Predicting the effects of management strategies requires knowledge of the hydrodynamic processes covering spatial scales of a few millimetres (turbulence) to several hundred kilometres (catchments), with a similarly large range of timescales from milliseconds to months. Predicting underlying water quality processes and their human and ecological impact is complicated as they are often dependent on contaminant concentrations. Current water quality modelling methods range from complex three dimensional computational fluid dynamics (3D CFD) models, for short time and small spatial scales, to one-dimensional (1D) time dependent models, critical for economic, fast, easy-to-use applications within highly complex situations in river catchments, water supply and urban drainage systems. Mixing effects in channels and pipes of uniform geometry can be represented with some confidence in highly turbulent, steady flows. However, in the majority of water network models, the standard 1D predictions can fall short. This talk will address some of these limitations related to aspects of mixing in urban drainage structures and pipes, focussing on modelling manhole mixing processes and unsteady flow effects in pipes.
