They protect sediment on the flats from erosion by currents and waves. Shellfish filter material from the water column and deposit it in the form of faecal pellets. This together with sediment is trapped between the shells. The reefs also provide a complex habitat for many other species, can provide economic benefits and contribute to a healthier ecosystem functioning.<\/p>\n        <\/div>\n    <\/div>\n    <div class=\"block-before-after-column\">\n        <div class=\"block-before-after-title\">Traditional design<\/div>\n                    <div class=\"block-before-after-figure\">\n                <img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"189\" src=\"https:\/\/www.ecoshape.org\/app\/uploads\/sites\/2\/2020\/05\/ErosionProtectionWithRubble-1-300x189.jpg\" class=\"attachment-medium size-medium\" alt=\"\" srcset=\"https:\/\/www.ecoshape.org\/app\/uploads\/sites\/2\/2020\/05\/ErosionProtectionWithRubble-1-300x189.jpg 300w, https:\/\/www.ecoshape.org\/app\/uploads\/sites\/2\/2020\/05\/ErosionProtectionWithRubble-1.jpg 571w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>            <\/div>\n                <div class=\"block-before-after-body\">\n            <p>Hard structures are common solutions when protecting shores and shoals against erosion.

Their reefs can protect shorelines and stabilize eroding (intertidal) areas. Apart from locally fixing sediment, they are able to influence tidal flow and wave action at larger scales, causing changes in depositional patterns. Oyster reefs are applied in many places around the world as a coastal protection method (e.g.&nbsp;<a href=\"http:\/\/ccrm.vims.edu\/livingshorelines\/\">living shorelines<\/a>), reducing hydraulic forces and enhancing sediment entrapment. In this project we constructed&nbsp;<a href=\"https:\/\/www.ecoshape.org\/en\/knowledge-articles\/artificial-reefs\/\">artificial reefs<\/a>&nbsp;in the Eastern Scheldt (SW Netherlands) to reduce the erosion of tidal flats. To be successful, the artificially placed substrate needs to develop into a living, persistent oyster reef and at the same time protect the tidal flat against erosion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Location: Eastern Scheldt (Eastern Scheldt), The NetherlandsDate: 2008 &#8211; present (BwN &#8211; projects ZW2.1 and ZW2.4)Involved parties: IMARES, Deltares, Rijkswaterstaat (WINN, Zeeland), NIOZ (former NIOO-CEME), Van Oord, TUD, Ecoshape.Technical Readiness Level: Environments: Topics: shellfish ecology, tidal flat protection, estuary protection, measures against erosion, biodiversity, ecosystem engineer, oyster.
