On the RIEGL website and in the RIEGL newsletter the latest publication by S. Vos et. al was mentioned, describing the CoastScan setup in Kijkduin and the 6-month data collection: Link to RIEGL-website. Next to a link to the publication in Nature Scientific Data, the text describes the motivation and highlights the specification of our RIEGL VZ-2000 laser scanner.
On 21-06-2022 the last scans were taken from the scanner location in Noordwijk. The scanner was removed in the following days and is sent for maintenance to the manufacturer. We thank Hotel Huis ter Duin for their cooperation and are now working on processing the collected scans of the past three years.
On 22 June 2022 we presented our latest work on assessing beach width variations on intertidal time scales using permanent laser scanning at the 5th Joint International Symposium on Deformation Monitoring in Valencia. The article with the details of this work will be published soon in the proceedings of the conference.
D.A.J. van Dieren: Anthropogenic beach deformations – Characterizing anthropogenic beach changes using laser scan and video data
D. Madi: Comparing the effects of winter storms Corrie and Eunice on Noordwijk using laser data
Debora van Dieren and Dalia Madia have successfully completed their final Bachelor projects and presented their results on June 16th. They used our CoastScan data set to quantify storm damages (Dalia) and detect anthropogenic activities (Debora). Congratulations to both!
On June 7th 2022 we presented the CoastScan project and our latest results at ISPRS 2022 in Nice.
The results were also published in a short article: https://doi.org/10.5194/isprs-archives-XLIII-B2-2022-1055-2022.
Today our article “A high-resolution 4D terrestrial laser scan dataset of the Kijkduin beach-dune system, The Netherlands,” (https://doi.org/10.1038/s41597-022-01291-9) by S. Vos, K. Anders, M. Kuschnerus, R. Lindenbergh, B. Höfle, S. Aarninkhof, S. de Vries was published in the nature scientific data journal.
The article explains our latest data publication (https://doi.org/10.1594/PANGAEA.934058) on the PANGAEA repository for earth and environmental science data. All point clouds collected at the CoastScan location in Kijkduin during a six months observation period from November 2016 to May 2017 can be found here.
From 16 February to 21 February 2022 three storms hit the Netherlands within only five days. The storms named Dudley, Eunice and Franklin caused very strong wind with wind speeds above 20 m/s and the effects on the beach were still clearly visible one day later (22 February).
In February 2021 Y. Schreijer successfully completed her master thesis with the title: ‘Visual insight into the temporal changes of sand patterns along the Dutch coast’ under the supervision of E. Verbree and P. van Oosterom (TU Delft) and P. Goessen (Hoogheemraadschap Hollands Noorderkwartier). For her master project she used CoastScan data to visualize dynamics that influence deformation processes of the coast.
The image shows elevation differences in Noordwijk after a storm hit the coast in early February 2020. A large sand deposition is circled in red.
In a comparison between two consecutive scans (about one hour apart) moving sand ripples, possibly caused by aeolian sand transport due to strong winds, are made visible.
The observation deck in the dunes in Noordwijk is located to the north of our laser scanner and just within the field of view. At our monthly round, where we check on the location, take some extra scans of the dune foot and collect GPS measurements of the beach, we also measure the GPS coordinates of this observation deck. Until the beginning of this year the deck was made of wood. Now, since February 2021 the deck is paved with bricks. This will increase the stability as a reference in our point clouds. But of course, this change does not allow for comparison with the data of the deck before it was paved.
