W.A.T.E.R. 2019 – Advanced hydraulic measurement techniques

The last week of June has been very enriching for Adina, Michal and Nitesh, as they attended the 4th Workshop on Advanced measurement Techniques and Experimental Research (W.A.T.E.R.) in Bologna, Italy. This edition was organized by the University of Bologna, Vrije Universiteit Brussel and the IAHR Experimental Methods and Instrumentation Committee (EMI) The workshop was focused on experimental methods applied in different hydraulics fields and combined theoretical sessions and hands-on measurement exercises in the laboratory.

Besides the different laboratory sessions (i.e. Particle Tracking Velocimetry, Particle Image Velocimetry, Acoustic Doppler Velocimetry, Laser Doppler Anemometry, Ultrasonic Pulse Velocimetry, Wave Gauges Pressure Transducers) held at the Laboratory of Hydraulic Engineering (LIDR-DICAM), a field trip to River Po Interregional Agency (AIPO, Boretto) was organized. There, measurements velocity profiles and river bed topography were taken by means of a UAV (Unmanned Aquatic Vehicle) with mounted ADCP (Acoustic Doppler Current Profiler), as well as a survey boat tour. Different scale hydraulic laboratory experiments were also visited.

Adina and Michal had the opportunity to present their research during the peer-2-peer session. Adina talked about the Optimization of hydrodynamic simulations in steep rivers, whereas Michal focused on Erosion protection in steep rivers.

The feedback received during their presentation, as well as the knowledge acquired regarding the different techniques, are of great value to the World of Wild Waters. For instance, fieldwork campaigns and laboratory experiments will be implemented for data gathering, callibration of hydromorphodynamic simulations and further flood risk analysis of selected study cases at different spatio-temporal scales. Getting to know new methodology has extended Work Package 2’s perspective on both optical and acoustic state-of-the-art laboratory and field measurement equipment.

MekIT’19 – 10th National Conference on Computational Mechanics

In June 03 and 04, 2019, Adina, Gebray and Michal had participated in the 10th national conference on Computational Mechanics-MekIT’19 held in Trondheim.

Adina’s presentation title was ” Materializing Natural Hazards:  Is Visualizing Hydrodynamic Fluid Simulations Relevant to Create an  Immersive Experience? ” which gave an insight on how the accuracy and time cost of simulation time shall be compromised each other in fluid simulations prepared for Immersive experience.

Gebray had presented a concept titled as ” Back Calculation of Quickness Test Using Herchel-Bulkley Model in REEF3D“. Herchel-Bulkley rheology model implemented in REEF3D ( an open source CFD code) is used to back calculate a simple quickness test using Herchel- Bulkley model parameters fetched out from viscometric test.

Michal’s presentation was titled as “2D Numerical Simulations of Flash Floods in Step Rivers” and was focused on the simulation of the flash flood event in Utvik (West of Norway) in 2017. TELEMAC-MASCARET software was used to carry out 2D hydrodynamic and morphodynamic (including bedload transport and bed evolution) simulations.

EGU General Assembly 2019

In April 2019, Michal went to present his research in form of a poster to European Geosciences Union (EGU) General Assembly in Wienna. The title of the poster was “Mapping areas exposed to erosion and water forces during extreme floods in steep terrain”. The contribution was focused on 2D numerical simulation of flash flood event in Utvik in 2017. Some connections for possible future cooperation have been made with researchers from Spain, France and Luxembourg. Also Google Flood Forecasting Initiative has been found relevant for WoWW project.
