Impact of a high rainfall event on the water level, current velocity, and total suspended solids in tidal flats environments of the estuarine Cruces River wetland, south-central Chile

The effects of a sudden rainfall (40 mm d-1) event on the surface waters covering muddy tidal flats were studied during April 2016 at estuarine Cruces River wetland in south-central Chile (~40ºS). study area included flooded vestigial tree trunks, which is evidence coseismic subsidence associated with 1960 Valdivia earthquake as source environmental variability. flat trunks registered fastest and highest depth inundation. In contrast, currents velocity total suspended solids' concentrations higher without trunks. Sudden events can significantly modify characteristics above sedimentary intertidal surfaces, where structures such are present.
