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.

22nd NRB conference – Canada

WoWW’s project leader, Oddbjørn Bruland, and Adina will present at the 22nd Northern Research Basins Symposium/Workshop held in Yellowknife, Canada, from August 18th to August 23th.

Oddbjørn’s presentation is titled “How extreme can specific runoff become in steep Norwegian catchments?” and covers the complex hydrology around the flood event that affected his hometown, Utvik, exactly two years ago, in July 2017. This data has been used to simulate the hydraulics and morphodynamics of the affected rivers both in Utvik and the neighbour village, Innvik, in the poster Michal and Oddbjørn presented at EGU in April this year.

Adina’s presentation is titled “River idealization for identification of critical locations in steep rivers using 2D hydrodynamic modelling and GIS” and tackles the characterization of any named steep river’s susceptibility to changing conditions, such as extreme rainfalls. The preliminary idealization of scenarios allows to detect parameters and sensitive areas worth focusing on during more detailed studies (such as channel bends) without the interference of case-specific hydrologic and topographic conditions. The study is time and cost-saving oriented, aiming at optimizing flood risk analysis.

Both presentations will take place on the first day of the conference, Monday 18th of August. We will update with anecdotes on this event; stay tuned!
