Seville, Spain (PortSEurope) November 13, 2020 – The Seville Port Authority (APS) started the maintenance dredging of the Eurovía del Guadalquivir (navigation channel) for 2020. The work consists of the maintenance of the current elevation levels in 14 sections of the navigation channel, without exceeding the maximum depths to guarantee full security in the access by sea to Seville. Maintenance work started in the area
closest to the lock and is the volume of sediments extracted is expected to reach 220,000 m³. From the sands extracted in this campaign, APS will allocate a part to the regeneration of the beaches of Bajo de Guía and La Calzada – Pools in Sanlúcar de Barrameda, as well as improvement and transformation of agricultural land and construction. For the wetlands for birds will be implemented new measures coordinated with the Superior Council of Investigations Scientists (CSIC) that will optimize the wetlands for aquatic birds created from of improved navigation. The experience will take place in the land dump of Butane 3, the one located further south of the lock and at the Gallows. The new guidelines will improve the management of the water sheet with the extension of the hydro period until the end of July, which will favor the nesting and reproduction of birds aquatic and of late species such as the gray teal. In addition, they will reinforce security on the islands to avoid the presence of predators and will have trunks or large branches for the creation of floating nesting areas. Also, the measurement of physical and biochemical conditions of the water is foreseen, such as dissolved nutrient levels. The protocol will test the efficacy of the rapid regeneration of plant formations with reed plantations. Recently, the Junta de Andalucía through its 2020 Environment award recognized the work of the Port Institution to conserve biodiversity in the estuary of the Guadalquivir. Seville is the first Spanish port that reconciles the management of sediment from maintenance dredging creating a habitat for birds aquatic. This practice is based on working with nature model that combines the protection and improvement of the environment in an efficient and parallel to economic development. The navigation channel ascends about 90 kilometers along the Eurovía del Guadalquivir. Due to the evolution of the river itself, along the estuary there are certain areas in which suspended particles settle that make it difficult to enter Seville by sea. For this reason, the APS promotes accessibility so that maritime traffic to the capital and the riverside municipalities is ensured. Maintenance dredging works are part of the operational measures included in the ‘Program for the optimization of the waterway’.
