That victor tube is the single phreatic sub-conduit among the many that potentially exist on a given bedding plane (or fracture plane) that is the first to reach a diameter capable of establishing turbulent-flow conditions. following this breakthrough the victor tube tends to enlarge more rapidly than other branching or subparallel alternatives and eventually captures much of the drainage within its field of influence [9].?

An assessment of the applicability of the heat pulse method toward the determination of infiltration rates in karst losing-stream reaches
Abstract:
Quantifying the rate at which water infiltrates through sediment-choked losing stream reaches into underlying karstic systems is problematic, yet critically important. Using the one-dimensional heat pulse method, we determined the rate at which water infiltrated vertically downward through an estimated 600 m by 2 m sediment-choked losing-stream reach in the Devils Icebox Karst System of Central Missouri. The infiltration rate ranged from 4.9 3 1025 to 1.9 3 1026 m s21, and the calculated discharge through the reach ranged from 5.8 3 1022 to 2.3 3 1023 m3 s21. The heat pulse-derived discharges for the losing reach bracketed the median discharge measured at the outlet to the karst system. Our accuracy was in part affected by significant precipitation in the karst basin during the study period that contributed flow to the outlet from recharge areas other than the investigated losing reach. Additionally, the results could be improved by future studies that deal with identifying areas of infiltration in losing reaches and how that area varies in relation to changing flow conditions. However, the heat pulse method appears useful in providing reasonable estimates of the rate of infiltration and discharge of water through sediment-choked losing reaches.
