Determination of velocity and direction of ground water flow in san andres island by means of radiotracers

The injection of radiotracers in 10 boreholes in San Andres island allowed the determination of direction and velocity of ground water flow. The basis of the technique relates to the application of a relationship existing between the observed concentration decrease of a radio tracer solution introdu...

La rápida o lentadesaparición del trazador indica velocidades altas o bajas respectivamente, las cuales pueden evaluarse en forma cuantitativa. El cambio de posición del trazador con el tiempo, indica la dirección del flujo subterráneo que lo arrastra en solución. Las técnicas esbozadas representan un método sencillo, económico y rápido de gran utilidad en la evaluación de parámetros importantes en cualquier estudio de aguas subterráneas.application/pdfspaDepartamento de Geocienciashttp://revistas.unal.edu.co/index.php/geocol/article/view/30404Universidad Nacional de Colombia Revistas electrónicas UN Geología ColombianaGeología ColombianaGeología Colombiana - An International Journal on Geosciences; Vol. 9 (1975); 51-64 Geología Colombiana; Vol. 9 (1975); 51-64 2357-3767 0072-0992Rodríguez N., César O.
