(Objetivo): Evaluar la evolución espacio-temporal del nivel freático utilizando datos de niveles de agua subterránea medidos en la red de pozos de monitoreo del acuífero Valle de Sébaco.  (Metodología): Se evaluó durante la época seca del 2010 al 2018 (9 años) la fluctuación de los niveles de agua subterránea, a partir de datos de niveles de agua medidos en la red de pozos de monitoreo del acuífero Valle de Sébaco. El enfoque geoestadístico que se empleó en este conjunto de datos, para revelar los modelos predictivos, fue el método kriging empírico bayesiano (EBK), que obtuvo una representación espacial de la superficie freática del acuífero y, posteriormente, fue utilizado para calcular la velocidad y aceleración del nivel freático.  (Resultados): Durante el período analizado los mapas de aceleración del nivel freático mostraron valores medios de -0.52 m/año2. Estos valores sugieren que una parte del acuífero está experimentando un descenso en los niveles freáticos. Este podría verse agravado rápidamente con los fenómenos climáticos y el aumento de la demanda del recurso.  (Conclusiones): El enfoque utilizado para la evaluación cuantitativa de los niveles de agua subterránea es adecuado para países que carecen de base de datos de parámetros hidráulicos específicos de un acuífero.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  (Introduction): Georeferenced environmental information from environmental institutions is the basis for improving environmental management and sustainability in the Latin American and Caribbean region.  (Objetive): To evaluate the spatio-temporal evolution of the water table using groundwater level data measured in the network of monitoring wells of the Sébaco Valley aquifer.  (Methodology):  The fluctuation of groundwater level was evaluated during the dry seasons from 2010 to 2018 (9 years), based on data on water levels measured in the network of monitoring wells of the Sébaco Valley aquifer. The geostatistical approach applied to this dataset, to reveal the predictive models was the Empirical Bayesian Kriging (EBK) method. This method obtained a spatial representation of the phreatic surface of the aquifer and was subsequently used to calculate the velocity and acceleration of the water table.  (Results): During the period analyzed, the water table acceleration maps showed mean values of -0.52 m/year2. These values suggest that part of the aquifer is experiencing a decline in water table levels that could be rapidly aggravated by climatic events and increased demand for the resource.  (Conclusions): The approach used for quantitative assessment of groundwater levels is suitable for countries lacking a database of aquifer-specific hydraulic parameters.]]></p></abstract>
