Zeeland Seaports has initiated a project with the aim to reduce the maintenance dredging effort. To gain insight into the driving forces behind this siltation, Sva\u0161ek Hydraulics has performed current and turbidity measurements and has carried out a <a href=\"https:\/\/www.svasek.nl\/model-onderzoek\/finel\/\">FINEL<\/a> model study.\r\n\r\nTo measure the current and turbidity in the port, an AWAC and OBS have been placed upon the seabed. During 6 weeks the current measurements have identified a complex 3D flow pattern in the entrance of the Braakmanhaven. During flood, inflow occurs in the upper part of the water column and outflow in the lower part of the water column. During ebb, the flow direction is the other way around and a strong inward current is detected near the sea bed.\r\n\r\nTurbidity measurements show high suspended sediment concentrations in the incoming current near the bed during ebb. This incoming current during ebb amounts for a significant part of the port\u2019s siltation.\r\n\r\nA FINEL model of the Western Scheldt has been set up to model the current. The model results show a good reproduction of the measured current. The driving force behind the complex 3D flow pattern appears to be a small natural density variation over the tide in the Western Scheldt.\r\n\r\nAfter calibration the model has been used to investigate the sensitivity of the 3D flow pattern to several interventions in the port geometry, and to investigate whether such interventions may reduce the siltation.\r\n\r\nA reduction of the port entrance width appears to be the most promising measure."},"slider":[{"image":2121,"video":""},{"image":2117,"video":""},{"image":2119,"video":""}],"expert_guy":{"left":{"title":"More information?","content":"Please contact Ype Attema.","linkedin_link":"https:\/\/www.linkedin.com\/in\/ype-attema-9803b084\/","email":"attema@svasek.nl"},"right":{"title":"Ype Attema","designation":"Lead expert morphodynamics","photo":1070}},"cta":{"title":"MORE INFORMATION ABOUT SVA\u0160EK OR OUR EXPERTISES?","text":"Please contact us or make an appointment.","link":{"title":"CONTACT US","url":"https:\/\/www.svasek.nl\/en\/contact\/","target":""}},"custom_links":{"linked_url":""},"hide":""},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project\/2124","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/types\/project"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/media\/2123"}],"wp:attachment":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/media?parent=2124"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/tags?post=2124"},{"taxonomy":"project_category","embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project_category?post=2124"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
