The Tagus river is one of the few rivers in the world to have an inverted delta. Its delta is wider at the beginning and narrows down as it approaches the sea, contrary to a typical delta. This is because it flows into the sea through a small opening in a valley.

An inverted river delta is a river delta in which the narrow end of the delta emerges on the seafront and the wide end is located further inland, so that with respect to the seafront, the locations of both ends of the delta are inverted.

Oct 1, 2019 · The stratigraphy of the Tagus river ebb-tidal delta off Lisbon (Portugal) is investigated using high resolution multichannel seismic reflection profiles with the purpose of searching for sedimentary or erosive features associated with landslides.

Sep 19, 2023 · The Tagus River crosses the entire Iberian Peninsula, with a length of 1038 km, from the Sierra del Albarracín, passing through several towns, until it reaches Lisbon, Portugal, and ends in the Atlantic Ocean.

Dec 4, 2024 · This study investigates the tsunamigenesis of a shallow-water submarine landslide, recently mapped at the mouth of the Tagus delta River, off Lisbon, Portugal. The Tagus delta landslide is estimated to be 8 ky old, with a depositional maximum thickness of ~ 20 m and a volume of approximately 0.27 km 3 , extending over more than 9 km in length ...

The seismic stratigraphy of the Tagus estuary ebb-tidal delta of Lisbon (Portugal) is investigated with the purpose of searching for evidences of possible sedimentary or erosive features associated with landslides or mass wasting deposits (MTD) events.

Jul 22, 2019 · Researchers of the Instituto Dom Luiz (IDL) identified a buried landslide that accounted for the collapse of half of the Tagus river ebb-tidal delta front possibly in the early Holocene. In this work, recently published in the journal Marine Geology , the stratigraphy of the Tagus river ebb-tidal

Jul 18, 2014 · The Tagus river delta is a sedimentary body in the Lisbon area with proven potential for the preservation of evidence of this kind of mass-transport deposits.

Sep 9, 2024 · Tagus ETD develops at the seaward end of one of the largest estuaries in Europe and faces the North Atlantic. The morphology of the Tagus ETD is typical of an ebb-tidal delta with...
