Spatial and temporal ion dynamics on a complex hydrological system: The lower Luján river (Buenos Aires, Argentina)

Mostrar todas las versiones(2)

The interplay of the geochemistry of the lower stretch of the Luján River is analyzed with its natural geomorphology (basin features), local hydrometeorology (tidal regime and "sudestada" events) and the impact of polluted tributaries. Major ions, dissolved heavy metals and limnological va...

description The interplay of the geochemistry of the lower stretch of the Luján River is analyzed with its natural geomorphology (basin features), local hydrometeorology (tidal regime and "sudestada" events) and the impact of polluted tributaries.
