Introduction:We investigated the magnitude and duration of desalination of Pulicat—a coastal lagoon ecosystem connected to the Bay of Bengal on the south-eastern coast of india—during the 2015 south india flood event which was a period of high-magnitude precipitation and riverine ***:We estimated freshwater runoff into the lagoon using flow accumulation models for a period of 55 days(November 1 to December 25,2015)using daily gridded precipitation data from the Global Precipitation Measurement and a digital elevation *** the estimates of freshwater runoff,direct precipitation and observed salinities,we simulated water and salinity fluxes of the lagoon using the Land-Ocean Interactions in the Coastal Zone ***,we also used Monte Carlo simulation to estimate the uncertainty in system salinity,the residual salinity at the boundary and the freshwater residence times in the ***:We estimated that a high volume(~760×10^(6) m^(3))of relatively low salinity waters(residual salinity=23.47 psu)had been exported from the lagoon to the Bay of Bengal during the period which is likely to have caused a strong dip in the daily salinity profile of the coastal *** contend that the lagoon experienced~40%desalination due to the 2015 event with a freshwater residence time of 18.5 ***:The study highlighted the short-term,high-magnitude desalination undergone by Pulicat lagoon during the 2015 south india *** the high residual and exchange volumes obtained from the study,we conclude that Pulicat could be a major exporter of relatively low salinity waters to the Bay of Bengal during monsoons.
