Abstract

In June and August 2023, the U.S. Geological Survey (USGS) conducted small Uncrewed Aircraft System (sUAS or drone) flights at five streamgages in the Upper Colorado River Basin, Colorado, USA. The objectives of this research were (1) compare maximum surface velocities and discharges derived from Space-time Image Velocimetry (STIV) and Particle Image Velocimetry (PIV) and (2) evaluate drone-based camera algorithms that rely on the entropy-based probability concept and mid-section method relative to standard discharge measurements.

基于熵的无人机摄像机放电概率概念和图像测速算法

2023年6月和8月，美国地质调查局（USGS）在美国科罗拉多州上科罗拉多河流域的五个河流进行了小型无人驾驶飞机系统（sUAS或无人机）飞行。本研究的目的是：(1)比较时空图像测速法（STIV）和粒子图像测速法（PIV）得出的最大表面速度和流量；(2)评估基于基于熵的概率概念和相对于标准流量测量的中段方法的无人机相机算法。

期刊介绍： The Journal of Hydrology publishes original research papers and comprehensive reviews in all the subfields of the hydrological sciences including water based management and policy issues that impact on economics and society. These comprise, but are not limited to the physical, chemical, biogeochemical, stochastic and systems aspects of surface and groundwater hydrology, hydrometeorology and hydrogeology. Relevant topics incorporating the insights and methodologies of disciplines such as climatology, water resource systems, hydraulics, agrohydrology, geomorphology, soil science, instrumentation and remote sensing, civil and environmental engineering are included. Social science perspectives on hydrological problems such as resource and ecological economics, environmental sociology, psychology and behavioural science, management and policy analysis are also invited. Multi-and interdisciplinary analyses of hydrological problems are within scope. The science published in the Journal of Hydrology is relevant to catchment scales rather than exclusively to a local scale or site.
