Hydrodynamic Analysis of the Jaruco-Aguacate Aquifer; Analisis hidrodinamico del acuifero Jaurco-Aguacate

Abstract

The paper shows the hydrodynamic analysis of the Jaruco-Aguacate aquifer using an unsteady groundwater flow mathematical model. The simulation includes conditions before and after pumping from a well filed, called El Gato, which is considered, as the most important water source for Havana city. The system is closed to the sea and conformed by an unconfined karstic aquifer with a well defined storage zone; its natural discharge flows through two spring groups. Results obtained with the model for the main spring discharge are near to the measured values, i. e. around 5 m{sup 3}/dec as the mean value for the period without main pumping station. Flow is reduced to 2.5-1.5 m{sup 3}/sec during pumping period but there are no data to confirm this result. Besides, a detailed study of the open boundary of the system is done when piezometric head variation in time is known. The mathematical modelling has been able to simulate the aquifer in its most general conception, in its regional as well as local representation, with a mean deviation of simulated head from observed values less than one meter in both analysed simulated periods.

[Spanish] El objetivo del trabajo fue realizar un analisis hidrodinamico del acuifero Jaruco-Aguacate antes y despues de la puesta en marcha del acueducto el Gato, una de las fuentes de abasto mas importantes de la ciudad de La Habana, Cuba, basado en un modelo matematico de simulacion de flujo subterraneo transitorio bidimensional. El acuifero es una llanura carstica cerrada al mar y libre; hacia su centro, la zona de almacenamiento esta bien definida; el sistema de descarga natural realiza por medio de dos grupos de manantiales. El resultado obtenido para el gasto del manantial coincide con los valores aforados para un valor medio de 5 m{sup 3}/seg en el periodo analizado antes del funcionamiento del acueducto, pero su valor se reduce, variando desde 2.5 a 1.5 m{sup 3}/seg, en el periodo posterior, sin embargo, no existe informacion para confirmar este ultimo resultado. Ademas, se estudia con detalle el comportamiento de los contornos abiertos del sistema, analizados como contornos de carga conocida en el tiempo. El modelo matematico ha simulado al acuifero en su concepcion mas general y los resultados demuestran que la informacion disponible y su procesamiento han sido adecuadas, con una desviacion promedio de las cargas simuladas menores de un metro en ambos lapsos de simulacion analizados.}
