22nd Northern Research Basins conference (Yellowknife, Canada)

The 22nd Northern Research Basins Symposium/Workshop was held in Yellowknife, Canada (by the Great Slave lake, one of the 10 largest fresh water lakes on the planet), from August 18th to August 23th 2019. There, Oddbjørn (project leader) and Adina (work package 2) presented their research regarding hydrology and hydraulics of flash floods in steep rivers.

Oddbjørn’s presentation was titled “Extreme flood in small steep catchments: how extreme can it become?” and covered the complex hydrology around the flood event that affected his hometown, Utvik, exactly two years ago, in July 2017. Also, several recent flood events affecting the southwest of Norway were presented. The take-home message was that these events are more extreme and more recurring than ever as northern regions are suffering a global warming trend. Adina’s presentation, on the other hand, tackled a virtual experiment on “River idealization for identification of critical locations in steep rivers using 2D hydrodynamic modelling and GIS“. This allows correlating hydrologic and topographic parameters to sensitive areas worth focusing on during more detailed studies (such as channel bends) without the interference of case-specific conditions. The study is time and cost-saving oriented, aiming at optimizing flood risk analysis.

A pannel of discussion was organized on the last two days, which led to very enriching and insightful discussion regarding how to better collaborate and achieve synergies among local field knowledge and the scientific community. Attendees were indigenous experts, the scientists presenting during the conference and the local pannelists invited.

The conference agenda included social activities, such as a boat trip to visit the indigenous Dene community nearby, learn about their traditions and how to use natural and forest resources and appreciate what nature has to offer. We got the chance to go on a guided tour around artsy Yellowknife, always accompanied by live fiddle music. Lastly, a banquet was held and a visit to Scotty creek closed the conference.


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.
