Worms and plants sediment experiment (Part 2) Deltares 2022-10-10 | How can worms and plants help dewatering soft sediment? (part 2).About 6 weeks ago, we started with a clay ripening pilot on our campus in Delft: youtu.be/JXG9WJQNsfk (Part 1)And for now, we see quite a difference already between the different sections: worms, plants or no treatment. In this video, our expert at Deltares, Miguel Angel de Lucas, gives you a visual demonstration with a 10kg kettlebell to show what the differences look like now, and he will tell you what he expects to happen next.With this experiment we test new nature-based solutions for the dewatering of soft sediment, for example mine tailings or sludge from waste water treatment. Nature helps to keep coasts, river areas and cities safe and viable.

Worms part 3 Deltares 2022-11-28 | We’re wriggling with excitement to let you know that our pilot, in which we tested new nature-based solutions for the dewatering of soft sediment, is complete! Three months ago we started the dredged sediment biologically enhanced ripening experiment on our Delft campus. In Europe alone we produce 200 million cubic meters of dredged soft sediment per year. It takes a lot of time and resources to dewater and turn it into, for example, soil. Endorsed by the results of our ongoing dredged sediment ripening pilot, we believe worms and plants can be part of impactful nature-based solutions to dewater soft sediment.Check out our expert Miguel Angel de Lucas, on the experiment’s results. You can clearly see the difference between the various sections (in this video in particular between worms and no treatment, in previous videos amongst all treatments). To reassure you in advance, Miguel managed to climb out of the soft sediment. 😉“We understand the physical processes involved in the biologically enhanced dewatering of fine sediments and can predict its behavior to a certain extent, but it does not stop to amaze seeing what just a couple of dozen mgs of worms per L of sediment can do to its dewatering speed and bearing capacity. Nature can be a powerful engineering tool, and we are only starting to unveil it” Missed the previous videos? 👉 Part 1 http://bit.ly/3EjlLnM👉 Part 2 bit.ly/3tK1cvPYou can read more about nature-based solutions here: http://bit.ly/3UgtybP

Worms and plants sediment experiment Deltares 2022-09-05 | How can worms and plants help dewatering soft sediment?In Europe alone we produce 200 million cubic meters of dredged sediment per year. It takes a lot of time and resources to dewater and turn it into, for example, soil.We are testing at Deltares how fast Oligochaete worms and plants turn almost 40 cubic meters of dredged sediment into soil. The same could be applied to other types of soft sediment as, for example, mine tailings or sludge from waste water treatment. This has been tested before on a small scale in the laboratory, and because of the positive results, the experiment is now scaled up. The testing will take a few months.Meanwhile, Miguel Angel de Lucas, expert at Deltares, will tell you more about his experiment.

Gloffis video v1 Deltares 2022-06-01 | Floods and droughts can cause serious disruptions to society and to the economy. The 2013 floods in Germany caused € 6 billion in lost manufacturing productivity, with another € 400 million in losses in other regions due to supply chain disruption. The Paraná river drought in 2021 threatened water supply in Argentina, increased energy prices in the region and resulted in a loss of more than 100 million dollars for the shipping sector.Floods can cause casualties, can inflict damage to physical property, temporarily interrupt social and economic activities and force a community to take emergency measures. Droughts limit the availability of water and food, often result in fewer employment opportunities, and reduced potential for energy production.The Deltares Global Flow Forecasting Information System isglobally available and locally applicable.

Hybride Energy Island Deltares 2021-12-16 | Part of the energy transition is taking place at sea. With the increasing demand for space in the North Sea, combining certain marine functions in a multi-use setting is an advantage. In the Deltabasin, a 50x50 m wave basin, Deltares and other parties are testing the forces of North Sea waves on a hybrid energy island. The island consists of a fixed and a floating part and stores sustainable energy generated offshore from wind farms and transports it to land. The fixed structure consists of a reef that provides protection for the floating platforms. Research in the basin must show whether the reef can slow down the waves sufficiently to create an acceptable swell in the inner ring. The reef is designed to both cope with the effects of rising sea levels and to support the ecosystem as much as possible. The hard substrate in the reef consists of rocks and is crucial for habitat recovery. The leezone of the reef gives seagrasses and seaweeds the space to develop and therefore provides CO2 absorption.

Waterveiligheidslandschappen Deltares 2021-10-14 | Bij waterveiligheidslandschappen staat de waarde van het gebied centraal. De verschillende maatschappelijke opgaven worden gebruikt om deze waarden te realiseren. Waterveiligheid is daarbij één van deze waarden. Door de maatschappelijke waarde van het landschap centraal te zetten kan aangehaakt worden op, en gebruikt gemaakt van, andere ruimtelijke en maatschappelijke ontwikkelingen die komende jaren en decennia de agenda’s gaan bepalen. Adaptatiepaden worden vertaald in transitie- en transformatiepaden voor een toekomstig landschap. Het concept is een gebiedsoplossing waarin alle aspecten die bijdragen aan waterveiligheid ruimtelijk zijn ingevuld, voor zover ze leiden tot een beheersbaardere gevolgschade bij overstromingen en dus tot een veerkrachtiger systeem. Dit concept is, en wordt verder, ontwikkeld door Deltares en hiermee stijgen we op en proberen we los te komen van het huidige denken in overstromingskansen en het garanderen van waterveiligheid.

Olympics severely affected if next super typhoon hits Tokyo Deltares 2021-06-21 | This video shows an example of a super typhoon hitting Tokyo during the Olympics, with corresponding extreme wind speeds and water levels as computed using Deltares' tool TCWiSE and the Delft3D FM suite.Typhoons (also known as tropical cyclones or hurricanes) are among the most destructive natural disasters worldwide. Typhoons can cause hazardous weather conditions including extreme rainfall and wind speeds, leading to coastal hazards such as extreme storm surge and wave conditions. For example, the Typhoon Hagibis (2019) resulted in the cancellation of several professional sporting events including Rugby World Cup matches and the Formula One Grand Prix race.In an internal study, researchers from Deltares analyzed the probability and possible consequences of typhoons during the Summer Olympics of 2021 in Tokyo, Japan, and what actions could be taken to minimize adverse consequences during the sporting event to the team and equipment.For more information see: https://www.deltares.nl/en/blog/olympics-severely-affected-when-next-super-typhoon-hits-tokyo-a-case-study-with-tcwise-to-understand-hazards-during-the-summer-olympics-of-2021/https://www.deltares.nl/en/software/tcwise/https://www.deltares.nl/en/software/delft3d-flexible-mesh-suite/
IMPAQT IMTA AE2020 with narrative Deltares 2021-05-17 | The concept of Integrated multi-trophic aquaculture (IMTA) has been identified as a promising solution for the sustainable development of aquaculture in many recent studies. Benefits include waste recovery or transformation, increased growth and diversity of produced species and improved use of coastal area. These depend, however, on the scale of its application and on the characteristics inherent to the receiving environment. Within the framework of EU project IMPAQT, Deltares has developed IMTA models, to understand and predict their benefits and limitations of this aquaculture concept. The model setup and results of two contrasting IMTA sites have been presented at the recent online Aquaculture Europe-2020 conference.
