UPC: Armour layer stability tests results published on the website

      | More

Under TASK 8.2: INNOVATIVE APPROACHES FOR REPRESENTING VARIABILITY AND UNSTEADINESS IN FLUME FACILITIES, UPC ran armour layer stability tests in the Wave Flume.

The objective of this study is to understand the laboratory effects of storm representation and test repeatability on damage measurements in the armour layer of a breakwater. For that, we study in a small-scale wave flume the effects of storm duration and storm sequencing on the stability of a two-layer cubic block breakwater. We start by simulating a real storm measured in the Mediterranean Sea.  Then three different representation models of the real storm are simulated: the classical model (Melby & Kobayashi, 1998) and two ‘Equivalent Magnitude Storm’ (EMS) models with triangular and trapezoidal shapes (Martín-Hidalgo et al., 2014; Soldevilla et al., 2015). All the four methodologies are repeated at least ten times. For the assessment of the damage in the armor layer of the breakwater, the damage parameter  (relative damage) proposed by Van der Meer is used.

Deltares Individual Wave Overtopping Tests

      | More

UnderTASK 8.2: INNOVATIVE APPROACHES FOR REPRESENTING VARIABILITY AND UNSTEADINESS IN FLUME FACILITIES, Deltares ran Individual Wave Overtopping Tests in the Scheldt Flume at Deltares.

A series of 27 tests in the Scheldt Flume at Deltares were used in this study. The tests were characterized by a breakwater with a smooth slope that was exposed to approximately 1000 waves. Between the different tests the water levels (3), wave height (3) and wave steepness (3) varied. In addition, the same series of 27 tests (and 6 repetitions) with the same wave forcing and similar breakwater shape, but with a rubble mount slope and crest wall, was used to broaden the applicability of the automated semantic segmentation techniques to more turbulent waves. These tests were used for model training, but model testing focused on the smooth slope tests since a better model/data comparison was possible. Data were acquired from 150 Hz high-speed video footage through the glass flume wall using a single camera mounted on a tripod approximately 1 m from the flume. A flow depth measurement at the breakwater crest is used to order the waves on impact. From the top 100 waves with largest flow depth in each test 50 waves are used in the analysis. Figure 1 shows an overtopping wave.

HYDRALAB+ Next Generation Researchers’ Workshop

Second Training Workshop for Next Generation to be done at iCIEM infrastructure at LIM/UPC (Barcelona): Representing environmental complexity in experimental design and acoustic measurement techniques

Fifteen of the best early career researchers coming from 12 countries have met in Barcelona from 6th to 8th Febraury 2018 in the facilities of the Maritime Engineering Laboratory of the Catalonia University of Technology (LIM/UPC) for a high-level 3 days’ workshop on the topic of the hydro-morphodynamic measurement techniques representing the environmental complexities.

Special focus has been given to acoustic measurements used both in the laboratory and in the field. Velocity structures, sediment concentration, free surface elevation and bed forms were the main topics reviewed during the workshop. The spokesmen were recognized professionals from the scientific and commercial world who made their knowledge available to the next generation researchers.

They have been able to see firsthand different sensors and to participate in masterclasses on the measuring principles, the instrumental deployment, both in laboratory and in the field, an application case and the systems commercially available. They also had the unique opportunity to work both in the large and small scale wave flumes of LIM/UPC setting up different pieces of equipment and collecting data-sets.

The last day the students worked on the collected data performing data analysis under the guidance of the professors and applying all the knowledge acquired in the previous days. The final keynote has been given by the professor and director of the LIM/UPC, Agustin Sanchez-Arcilla on how important are these measurements for climate change and adaptation for coastal processes. 

We would like to take this opportunity to tahnk all the people involved in the preparation and organisation of this event and in particular, staff at the Catalonia University of Technology and all the speakers on these 3 day event.


4TH HYDRALAB+ PROJECT EVENT IN GRENOBLE, FRANCE 22nd to 26th January 2018

      | More

The HYDRALAB+ project of the Horizon 2020 Programme of the European Union, held its 4th project event from 22nd to 26th January 2018 in the French city of Grenoble. The meeting brought together all the participants in the project, including project partners and associate partners. This was the opportunity for the project team to analyze the progress of the planned programming in the 3 different Joint Research Activities and Transnational Access.

The HYDRALAB+ meeting salso included an advanced workshop on Protocols for scaling morphodynamics in time (as part of the JRA1 RECIPE: CLimate change in physical experiements research) and  a workshop on Climate Change Community Stakeholders that saw a number of very interesting presentations by project stakeholders including  presentations from the Catalan Office for Climate Change and a presentation on EU climate adaptation strategy for Flood risks from the EU Joint Research Centre.

Finally the CNRS, Laboratoire LEGI in Grenoble (France) also organised on Tuesday 23rd January a technical fieldtrip to the LEGI laboratory including the Corioluis platform and a participant dinner on the 24th.

We look forward to our next meeting in Catania, Italy in September 2018.
