Interactions and exchanges between surface water, groundwater and the atmosphereare some of the most relevant functions that regulate environmental characteristics inwetlands. These functions depend on environment attributes such as topography,geological-geomorphological setting and, in the case of coastal wetlands, therelationship with tidal flows. The aim of this work is to analyse the water flows indifferent landscape units of the wetland in the coastal plain of the Río de la Plataestuary within the Parque Costero del Sur biosphere reserve. For this purpose,monthly water balances and groundwater level measurements were compared withdaily precipitation and tidal height data from the Río de la Plata estuary. The resultsshow how water dynamics in the wetland responds to different geological-geomorphological and climatic controls. The main inlets and outlets of water, as well asthe flow exchanges, vary according to the different landscape units, forming a complexsystem on which the main ecological features depend.
