%X the nimboyores aquifer, located in the province of guanacaste (costa rica) has been defined in this work as an unconfined aquifer, it is composed of three layers: the deepest one is a thick colluvium, the intermediate is a thin colluvium and at the top there is a sandy clay soil. the basement depth varies between 30 and 45 m. this model was obtained by correlating the results of 7 vertical electrical soundings with 50 wells with lithological information provided by the senara. the hydraulic conductivities of such layers are respectively 300, 60 and 10 m/d. the total recharge to the aquifer is of 1211 l/s, obtained from the water balance. based on the record levels in 14 wells collected during 7 years monitored by senara, static levels were established for the driest month recorded. the conceptual model improved the understanding of the groundwater flow and the influence of the geological setting.
