Every nation member of the United Nations (UN) celebrates the World Water Day (designated in 1992 by the UN) to increase global awareness on the importance of water and WoWW was invited to present during the World Water Day held in Oslo, Norway (postponed from March to November 2020 due to the pandemic).
The main topic for the World Water Day in 2020 is Water and Climate Change and the connection between these two (for instance, floods, droughts, storms, water quality and even the spread of water-borne diseases and its effect in tourism). This comes hand in hand with WoWW’s focus on water-derived natural hazards, such as flash floods and quick clay landslides.
Adina presented “Serious gaming in the World of Wild Waters project and 3D visualization of floods” during the second session. WoWW’s motivation, project structure and potential applications were shown and exemplified with excerpts of the research carried out to date by all the WoWW modules. Moreover, the project’s current challenges were exposed and public participation and collaboration was encouraged. The presentation was recorded by the organizing committee and it’s available down below.
As every year in such occasion, the United Nations has released the “World Water Development Report 2020 – Water and Climate Change” (document available here and live presentation available here). Additionally, the topic selected for World Water Day in 2021 is #Water2Me.
The International Association for Hydro-Environment Engineering and Research (IAHR) has hosted their first Young Professionals congress this week. The congress aims to encourage networking and mentorship for young researchers in fields such as Fluvial Hydraulics, Hydroinformatics, Flood Risk Management or Sediment Transport, Experimental Methods and Instrumentations, among others. The event was held virtually (streamed live in YouTube) and gathered nearly 1,000 attendees.
Michal, Nitesh and Adina took part in the congress and the latter two presented their most recent findings in form of extended abstracts and posters in the Flood Risk Management session, chaired by Stefan Haun (Stuttgart University in Germany) and Benjamin Dewals (University of Liège in Belgium), and moderated by José M. Carrillo (Technical University of Cartagena in Spain). Both presentations were recorded by the congress organizing committee and are available down below.
Michal and Nitesh presented “Coupled hydrodynamic and hydrologic modelling using Telemac-2D” in a different study case in western Norway. The focus was on testing the effect of modelling short and long term Antecedent Moisture Conditions, mesh size and steep slope correction. The congress proceedings will be available in the e-Library of IAHR.
After a considerable long period without fieldtrips due to the SARS-CoV-2, and just before a new wave hit us all, WoWW sought for calibration and validation data for its hydraulic numerical models. Although the likelihood of flooding decreases considerably during the cold Norwegian Autumn, Oddbjørn, Michal and Adina visited two mountainous localities, namely Oppdal in Central Norway and Stryn in West Norway.
Vekveselva river (in Oppdal) has a step-pool morphology and a steep slope, which makes it very attractive from the hydraulic and geomorphological perspectives, as this makes the river and valley susceptible to both floods and landslides. The weather was cloudy and slightly windy and snow has started to accumulate in the last few weeks (see the first gallery of photos below). These factors, together with an unstable phone/GPS signal, made the task of using an Unmanned Aerial Vehicle (aka drone) challenging. In addition, most of the selected reach had ice accumulation. In order to gain expertise and overcome the aforementioned challenges, WoWW allied with the department of Geography at the Norwegian University of Science and Technology.
The Norwegian Meteorological Institute forecasted heavy rain for Storelva river in Utvik (in Stryn) during early November and Michal and Adina drove to the West of Norway spontaneously. Although the weather resulted drier than predicted and the river barely carried water, the snow from the mountains has not yet reached the river downstream by the fjord. The wind did not encourage to fly the drone, however, they did experiment with acoustic (i.e. ADCP) and salt dilution gauging methods (see the gallery of photos below).
Storelva river in Utvik was flooded during summer 2017 and now flood-protection measures have been implemented. The channel has been excavated and a dyke has been built to protect the adjacent houses, formerly affected by the flash flood. The new channel shape demands for a new data set for ongoing research on flood risk in Stryn. The Norwegian winter is coming and the field work season comes to an end. Further attempts to obtain field data in Central and West Norway will be conducted during spring, once the snow has melted. A manuscript analyzing the hydrology of the 2017 flood was published in Hydrology Research this spring, and the efforts are now focused on understanding the hydrodynamics and the morphodynamics of the flood.
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.
