Groundwater recharge can be understood as the process where rainwater infiltrates into the soil, travelling through the unsaturated zone and reaching the aquifer. Identification and quantification of this parameter is of vital importance for planning and managing water resources. The aim of this paper is to quantify the recharge rate in the Inter-mountainous Pampa Plain by using 4 different methods including hydrometeorological, chemical and hydrogeological data. The recharge values range from 9 to 21% of the total rainfall with a mean value of 14%. Major advantages, disadvantages and results of the different methodologies are discussed.

Palabras clave : groundwater; recharge; pampean plain; phreatic level.
