%X The Bay of Saman芍, formed by tectonism and sedimentation, is delimited to the north by the peninsula of the same name, to the south by the north slope of the Eastern Mountain Range and Los Haitises National Park, to the east by the Atlantic Ocean, and to the west by the ancient Gran Estero, today the Lower Yuna. There follows a process of continuous degradation by the existing tectonic forces and the sediment contributions by the Yuna, Yab車n, and La Yeguada rivers to the south as well as by the landslides of the mountainous area of the Saman芍 Peninsula, during periods of storms and hurricanes. The coastal area of Saman芍 Bay has altered by 2.17 km2 at the mouth of the Yuna River from 2003每2015. The high turbidity level has affected coral reefs and marine species.ˋ Theˋ mangrovesˋ areˋ lostˋ fasterˋ thanˋ theyˋ areˋ regeneratedˋ byˋ theˋ coastline＊s change. Variations in the elemental compositions of calcium and iron show the terrigenous influence on the dynamics of the bay during Extreme Weather Events (EWP) in the river basins that flow into it. Abrupt changes in the rainfall regime produced an equal change in the estuary sedimentation regime, according to the 210Pb. In the 2007每2016 period, a column of sediment that reached 38 cm and a 12 cm to 8.4 km column were deposited 4 km southeast of the municipality of S芍nchez and east of the mouth of the Yuna River. The Sedimentary Accumulation Rate is very high, and
the content of heavy metals exceeds the threshold values of Table SQuirt
