However, the 20th century has altered this natural dynamic with hydraulic works that guarantee water supply and prevent flooding.<\/p>\n\n\n\n<p>The Port of Seville will utilize the sediments periodically dredged from the river to maintain its navigation channel, reinforcing the riverbanks, which are weakened in some areas and heavily eroded by large ships on rivers like the Guadalquivir and the Dordogne.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"964\" height=\"542\" src=\"https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-2.webp\" alt=\"Merchant ship sailing through the Guadalquivir Estuary, with Do\u00f1ana to the right \u00a9 Yuntas\" class=\"wp-image-646\" srcset=\"https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-2.webp 964w, https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-2-300x169.webp 300w, https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-2-768x432.webp 768w, https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-2-600x337.webp 600w\" sizes=\"auto, (max-width: 964px) 100vw, 964px\" \/><figcaption class=\"wp-element-caption\">Merchant ship sailing through the Guadalquivir Estuary, with Do\u00f1ana to the right \u00a9 Yuntas<\/figcaption><\/figure>\n\n\n\n<p>The innovation being tested involves using the sediments to construct solid blocks of compacted earth. These blocks, created using 3D printing, will contain cuttings of native trees and seeds of native riparian flora.<\/p>\n\n\n\n<p>They will be built on-site and, under the supervision of the Do\u00f1ana Natural Area, placed on the riverbank separating the estuary from the protected marshland.<\/p>\n\n\n\n<p>As the action of the tides and waves generated by ships degrade these blocks, the seeds and cuttings will be released, replacing the structural resistance of the blocks with a root system that will give rise to a new riparian forest. It is therefore hoped that this will be not only a sustainable solution, but also a long-lasting one.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"964\" height=\"538\" src=\"https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-3.webp\" alt=\"Pilot Site, on the Do\u00f1ana shore, where the river has eroded the bank \u00a9 Yuntas\" class=\"wp-image-645\" srcset=\"https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-3.webp 964w, https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-3-300x167.webp 300w, https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-3-768x429.webp 768w, https:\/\/rivers-rest.yuntas.eu\/wp-content\/uploads\/2026\/04\/piloto-4-3-600x335.webp 600w\" sizes=\"auto, (max-width: 964px) 100vw, 964px\" \/><figcaption class=\"wp-element-caption\">Pilot Site, on the Do\u00f1ana shore, where the river has eroded the bank \u00a9 Yuntas<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Restoration of riverbeds, banks, and riparian forests in estuaries.
