  abstract = {{I}n highly anthropized watersheds, surface water tributaries may carry unexpected high quantities of radon and radium to coastal lagoons. {I}nvestigating submarine groundwater discharge ({SGD}) with radionuclide tracers is therefore a complex task. {I}n order to quantify {SGD} and decipher the influence of the different water sources, we combined a radon ({R}n-222) and short-lived radium ({R}a-223, {R}a-224) survey with the hydrodynamic modeling of a lagoon. {W}e applied it to the {M}ar {M}enor lagoon ({SE} {S}pain) where surface water tributaries and undocumented emissaries carry water from groundwater drainage and brines from groundwater desalinization. {W}e identified the areas of influence of the plume of radionuclides from the river, located major areas of {SGD} and proposed a location for two submarine emissaries. {P}orewater, i.e. interstitial water from underlying sediments, was found to be the most representative {SGD} end member, compared to continental groundwater collected from piezometers. {M}ass balances in winter and summer seasons provided yearly {SGD} fluxes of water of 0.4-2.2 10(8) 3m(3)/y ({R}n-222) 4.4-19.0 . 10(8) m(3)/y ({R}a-224) and 1.3 . 10(8) m(3)/y ({R}a-223, measured in winter only). {T}idal pumping was identified as a main driver for recirculated saline groundwater, while fresh submarine groundwater discharge from the aquifer ranged between 2% and 23% of total {SGD}.},
