Abstract
A sandbox test system and method for a karst aquifer based on tracer-hydraulic tomography inversion, including a visual sandbox apparatus, a karst conduit, a water flow control apparatus, a horizontal well, a data acquisition apparatus, and a data processing apparatus. The visual sandbox apparatus forms a sand layer packing space. The karst conduit is buried in a sand layer. The water flow control apparatus is a constant water head storage tank. A back plate is provided with a horizontal well mounting hole and tracer adding hole. The horizontal well is mounted in each horizontal well mounting hole. A monitoring well is connected to a seepage pressure sensor or an electrical conductivity sensor. A water injection and pumping well is connected to a peristaltic pump. The electrical conductivity sensor, seepage pressure sensor, and peristaltic pump connect to the data acquisition apparatus. The data acquisition apparatus connects to the data processing apparatus.
