Abstract: An underwater detector includes a sealed enclosure, inside an infrared sensor module is disposed. The module rotates around a spindle at a fixed angular velocity along a horizontal plane. An electronic compass disposed on the module. A bottom of the sealed enclosure connected to an indicator through a rotary shaft, and the indicator rotates around the rotary shaft on the horizontal plane. The indicator includes a head and tail fin. A light source emits a light beam vertically upwards on the tail fin. The module is configured to trigger, when receiving the light beam, the electronic compass records a real-time direction relative to the spindle, which is processed by a processor module to obtain a direction of the water flow. A spring connects between the head and tail fin. The infrared sensor module transmits a moment of receiving the light beam to the processor module to calculate the water flow.

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.
