The Canal de Ovar, also known as Ria de Ovar, is the northern section of the Ria de Aveiro, between São Jacinto and Ovar, in the district of Aveiro. The shallow coastal lagoon, about 25 kilometers long, is the largest of the three main channels of the Ria (Ovar, Ílhavo and Mira) understood as a unique space in the context of Portugal and Europe, given the environmental and landscape qualities of high scientific value, with conditions for the practice of bird watching and other activities, such as rowing, sailing, canoeing, stand up paddle or simple boat or moliceiro trips. The Ria de Aveiro has been the target of a silting intervention since 2019, with the aim of strengthening the margins in low areas threatened by the advance of water, to protect people and goods and to restore the supply of sediment to the coast, and complementarily, contribute to the improvement of navigation conditions in the estuary and accessibility to some of the quays, which are quite silted, as well as to maintain an ecological flow, in order to preserve ecosystems
