| Description | Three quantitative tracer tests were performed in close surroundings of Suchdol municipality in Moravian Karst using fluorescein dye. In all three cases the water arrived into Konstantni přítok underground spring situated in Amateur Cave. Thus these tracer tests disproved former assumption that Suchdol ponors are drained into Štaiger Cave, which was based on single tracer test using carcoal cartridges. This shows the need to support the preliminary results based on carchoal by subsequent quantitative tracer tests. Based on tracer test and other data (volume of part of Konstantní přítok explored by divers) we suppose that roughly 2500 m long unknown cave segment between Suchdol and Konstantní přítok is formed either by stream with open surface (more probably) or by phreatic conduits with very small volume. To distinguish between these two possibilities we propose to make hydraulic head propagation test in the future. During one of the tracer test a new device (design by V. Kahle) for continuous sampling of fluorescent dye was successfully tested. Having very simple and cheap design and containing no moving parts it could be possibly applicable for sampling in hardly accessible parts of caves. |
