摘要：In this paper, in a karst fissure well with a large water depth, the flow velocity and flow direction of the monitoring wells at different depths (239m, 157m) were measured using The AquaVISION Colloidal Borescope produced by Geotech, USA. The results showed that, the flow direction of 239m deep karst water was 322.73°(37.27°North West), the flow velocity was 1496.60 μm/s. The flow direction of 157m deep karst water was 309.18°(50.82°North West), the flow velocity was 1032.0 μm/s, the flow direction of groundwater was Northwest, and the flow velocity gradually decreased from deep to shallow.
