Description:

This paper is dealing with a detection of ground water flow in a granite massif. The flow was studied between boreholes of a testing polygon situated in a granite quarry. So called cross-hole (C-H) tests were used to detect fracture based connection between the boreholes. The tests were proceeded in steady-state ground water flow conditions. There were TV cameras used to detect a uranine tracer. The cameras were equipped by an orange filter and well defined blue light. A geometrical model of the fracture system in the area of interest was proposed according to C-H tests data. A hydrogeological model was calibrated using the very same data. Results pointed out subhorizontal fracture connection between the boreholes. Main advantages of the TV camera usage are possibil ities of accurate localization onto a structure, an immediate detection of tracer onset time and a continual data record., Karel Sosna, Milan Brož, Michal Vaněček and Michal Polák., and Obsahuje bibliografické odkazy
