Abstract

This study presents techniques based on the use of fluorescent quinine as a visual tracer for surface flows, to assess surface flow velocities in channels and streams under low luminosity conditions. Fieldwork was conducted in three open channels, with different hydraulic characteristics. A quinine solution, in both liquid and solid (ice cube) forms, was applied on the water flow surface and an Unmanned Aerial System (UAS) was used to record the movement of the fluorescent quinine. The results were compared to the velocities estimated using the thermal tracer technique and flowmeter-based velocity maps. The findings show that the quinine solution, in both liquid and solid forms, can be used to estimate open-channel surface flow velocities under low luminosity conditions. While the solid form of the quinine tracer was applied in a smaller volume than the liquid tracer, its fluorescence effect persisted longer. By comparison, the liquid tracer had the advantage of continual availability and was devoid of the constraint of melting.

基于荧光奎宁的跟踪技术在低亮度条件下使用UAS测量明渠表面流速
本研究提出了基于使用荧光奎宁作为表面流动的视觉示踪剂的技术,以评估低亮度条件下通道和溪流中的表面流速。现场工作在三个具有不同水力特性的明渠中进行。将液体和固体(冰块)形式的奎宁溶液应用于水流表面,并使用无人机系统(UAS)记录荧光奎宁的运动。结果与使用热示踪技术和基于流量计的速度图估计的速度进行了比较。研究结果表明,液体和固体形式的奎宁溶液都可以用来估计低光度条件下明渠表面的流速。虽然固体形式的奎宁示踪剂比液体示踪剂应用的体积小,但其荧光效果持续的时间更长。相比之下,液体示踪剂具有持续可用性和不受熔化限制的优点。

期刊介绍: Hydrology Research provides international coverage on all aspects of hydrology in its widest sense, and welcomes the submission of papers from across the subject. While emphasis is placed on studies of the hydrological cycle, the Journal also covers the physics and chemistry of water. Hydrology Research is intended to be a link between basic hydrological research and the practical application of scientific results within the broad field of water management.
