Granada 2022 Industry Stream Event (GISE)
Conveners: Dr. Damien Violeau (Electricité De France, Division R&D), Prof. Miguel Ortega-Sánchez (University of Granada, Spain) & Tom Soo (Executive Director, IAHR)

GISE will include special sessions about the recent achievements of Industry in delivering industrial developments and applications, with focus on the following topics:

• Advanced computational simulations in hydraulics for practitioners
• Modern laboratory and field measurement for Industry in environmental hydraulics
• Industrial projects in hydraulics and hydro-environmental engineering

Description: One of the strategic orientations that IAHR prioritised is to “act as a global voice on behalf of the Hydro-Environment Engineering Industry and Research community”. This implies building strong relationships with practitioners and engineering organisations, whilst at the same time continuing to foster the academic and research-oriented activities of IAHR. The “IAHR Industry Stream for Practitioners, Regulators and Engineering” seeks to establish and build those relationships, via a series of inaugural actions that shall take place within the framework of the IAHR World Congress, with the aim of providing a platform for those stakeholders, individuals, organisations, and authorities who implement real world solutions over the full water cycle to interact, raise priority issues and advocate solutions at the global institutional level. The Granada 2022 Industry Stream Event (GISE) will include special sessions about the recent achievements of Industry and Academia in delivering industrial developments and applications.

From White River to Green River: Field Investigations and Analyses
Conveners: Prof. Hyoseop Woo (Gwangju Institute of Science and Technology, South Korea), Dr. Takashi Asaeda (Saitama University, Japan), Dr. Rohan Benjankar (Southern Illinois University, USA), Dr. Alicia García Arias (Universitat Politècnica de València, Spain), Diego M Garcia De Jalon Lastra (Universidad Politecnica de Madrid, Spain), Prof. Dongdong Shao (Beijing Normal University, China), Prof. Mark Dixon (University of South Dakota, USA), Ms. Fumiko Imamura (Nippon Koei Institute, Japan), Dr. Makoto Hyodo (IDEA Consultants, Inc., Japan), Dr. Yuichi Kayaba (Public Work Research Institute, Japan), Prof. Sung-Uk Choi (Yonsei Univ., Korea), Prof. Gregory Egger (Karlsruhe Institute of Technology)

Description: The riparian landscapes in many river reaches have been changing from white sand/gravel bars to greenery lands covered with grass, bush, and mature trees. This change can change the riparian ecosystem and the river’s engineering functions relevant to the flood management and sediment regimes. Although the succession of recruitment to mature vegetation is considered a part of natural phenomena, the rate of change has been affected by anthropogenic activities caused by alteration of the flow and sediment regimes and water quality traits of the river system. This special session focuses on the cause and effect of “greening” of the riparian landscape on the riparian ecosystem, flood management, and sediment regimes.

Reservoir Sedimentation in semi-arid and arid environments. A comparative analysis from vulnerability of climate change in sensitive environments
Conveners: Prof. Agustín Millares (University of Granada, Spain), Kamal El Kadi Abderrezzak (National Laboratory for Hydraulics and Environment, France), Eddy J. Langendoen (United States Department of Agriculture, USA) and Sameh Kantoush (Kyoto University, Japan)

Description: Analysing erosive and sedimentary processes in arid and semi-arid basins is key to water resource management in a global change context. The dynamics of sediment transport at the catchment scale is greatly influenced by the torrential nature of rainfall, snowmelt cycles, high local atmospheric and topographic gradients as well as soil geology and land use. This special session proposes a comparative analysis of the erosive processes that lead to sedimentation in reservoirs in semi-arid and arid areas. Field monitoring, innovative measurement techniques, numerical modelling and application to sediment transport and reservoir sedimentation will be specially discussed.

Remote Sensing and GIS in river engineering
Conveners: Prof. Michael Nones (Institute of Geophysics Polish Academy of Sciences, Poland), Dr Maria Nicolina Papa (University of Salerno, Italy) & Dr Paolo Paron (IHE Delft, The Netherlands)

Description: The combination of Remote Sensing with Geographic Information System is becoming an important field of research in the Earth Sciences, covering several aspects such as river hydro-morphodynamics and fluvial engineering, e.g., flood mapping and flood resilience, surface water level and water storage, tracking of fluvial landforms, urbanization in riverine regions. This Special Session aims to gather researchers, practitioners and water managers working on problems related to the management of fluvial ecosystems using remote sensing and GIS tools, and to show recent advancements in this research field.

Snow-fed areas and hydraulic systems management: challenges, chances, and solutions
Conveners: Prof. María J. Polo (University of Cordoba, Spain) & Dr. Claudia Notarnicola (EURAC, Bolzano-Italy).

Description: Snow is a determinant factor for the management of hydraulic systems in many regions in the world. Water storage and supply, protection against floods and droughts, hydropower generation, irrigation channels in mountain areas, or springs exploitation are just examples of services provided by different hydraulic systems. The estimation of water equivalent volumes, snowmelt initiation, and snow-fed streamflow duration is not straightforward, and the impacts of the variability of climate and the future of snow covers pose key questions to optimize decision-making systems. This special session addresses the challenges of the variability of the snow regime for hydraulic systems management, with focus on chances and solutions to improve their operation on different time scales.

Integrating Ecohydraulics and Ecohydrology in Environmental Flow Assessments
Conveners: Prof. Francisco Martínez-Capel (Universitat Politècnica de València, Spain), Shinji Fukuda, Institute of Agriculture (Tokyo University of Agriculture and Technology, Japan), M. McClain (UNESCO-IHE, The Netherlands), D. Tonina (University of Idaho, USA), G. Pasternack (University of California Davis, USA) & R. Tharme (Director of Riverfutures, England).

Description: Many tools, including models, methods, or frameworks, are available to assess environmental flows (e-flows). However, many worldwide e-flows studies have focused only on minimum flows, neglecting the diverse ecologically-relevant components of the rivers and streams flow regimes. Major challenges remain in the assessment and implementation of e-flows or environmental water assessment methods. This session aims to share experiences on the interaction between Ecohydraulics and Ecohydrology, from different perspectives. This can include scientific studies at the microhabitat, mesohabitat or larger scales, integrative and holistic methods or procedures for e-flow assessments or challenges in studies of ecological responses to hydrological alteration.

Ecohydraulics 2021: Novel methods to investigate flow-biota interactions numerically, in the lab and in the field
Conveners: Prof. Rafael O. Tinoco (University of Illinois at Urbana-Champaign, USA), William Nardin (University of Maryland, USA), Maria Maza (University of Cantabria, Spain) & Julia Mullarney (University of Waikato, New Zealand).

Description: The multidisciplinary nature of ecohydraulics research brings together state-of-the-art research tools and approaches from many scientific fields. Contributions from research groups developing or adapting technologies and/or modeling strategies to study flow-biota interactions at multiple scales, from small-scale fundamental processes to field-scale feedbacks and interactions, are expected. Focusing on the methods, this session will provide a window into new developments to expand the use of new sensors, advanced quantitative remote sensing, thermal imaging, UAV, multispectral cameras, LIDAR, discrete element methods (DEM), among others, to assess short- and long-term hydro-and morphodynamic interactions between organisms and their habitats.

Environmental Hydraulics Related to Aquaculture
Conveners: Prof. Dongdong Shao (Beijing Normal University, China), Alan Cuthbertson (University of Dundee, UK) & Ruo-Qian Wang (Rutgers University, USA).

Description: Due to the increasing human demands of protein and dwindling wild fish and shellfish stocks in the World’s seas and oceans, aquaculture has been growing rapidly in recent decades on a global scale. This rapid expansion of aquaculture industries is challenged by a number of environmental concerns, including nutrient enrichment and waste dispersion, disease infestations and spreading, and sea floor deterioration below the farms. Some of the topics of this special session include flow interaction with aquaculture structures; near- and far-field mass transport processes; pathogen dispersal and waste particulate transport processes; mixing zone regulation for aquaculture effluents; and relevant field scale monitoring and/or modelling techniques.

Green infrastructure and sustainable urban drainage systems
Conveners: Prof. Leonardo Nanía (UGR, Spain) & Ignacio Andrés‐Doménech (UPV, Spain).

Description: Green Infrastructure is a strategically planned network of natural and semi-natural areas with other environmental features designed and managed to deliver a wide range of ecosystem services such as water purification, air quality, space for recreation and climate mitigation and adaptation. In the case of urban drainage, green infrastructure encompasses a variety of water management practices, such as green roofs, vegetated swales, rain gardens, and other measures that capture, filter, and reduce stormwater. This special session aims to provide a forum to expose specific topics related to green infrastructure in urban drainage, its applications in different types of climates, and latest advances in numerical simulation.

Implementing Nature Based Solutions – bringing science to practice
Conveners: Dr. Ellis Penning (Deltares), Peter Goodwin (UMCES, USA), William Nardin (UMCES, USA) and David Wegner (UMCES, USA).

Description: There are many challenges in implementing NBS within a larger framework, ranging from technical uncertainties, perception by engineers or communities and effective governance to administer the project throughout its design life. During this special session we focus on the science-policy-financing interface needed for the implementation of Nature Based Solutions in applied cases and the way that IAHR members can contribute to this: how do we bring science to practice? What scientific advances are needed and what can we learn from both successful and failure cases?
