“…Using this dataset, we calculated performance metrics to assess the tracking approach at the reach‐scale and compare both interpolation methods. The coefficient of determination R2 and the root mean squared error RMSE have been used in similar settings (e.g., Arseni et al, 2019; Bandini et al, 2023; Dietrich, 2017; Islam et al, 2022; Javernick et al, 2014; Kinzel et al, 2021; Rishikeshan et al, 2014). We calculated both metrics comparing manual measurements once to MA estimates and once to IDW estimates.…”

“…Manual surveys with traditional survey rods are labor‐intensive and time‐consuming. Recently, Real‐Time Kinematic (RTK) Global Navigation Satellite System (GNSS) technology has been used to obtain instantaneous, high‐precision altitude measurements at cross‐sectional measurement points (e.g., Bandini et al, 2023; Kasvi et al, 2019; Kinzel et al, 2021; Woodget et al, 2015), requiring each point to be approached individually, though. More sophisticated remote‐sensing technologies become increasingly available and can be suitable over a wide range of scales (Carrivick & Smith, 2019; Smith & Vericat, 2014; Tomsett & Leyland, 2019).…”

This article investigates the performance and accuracy of continuous Real‐Time Kinematic (RTK) Global Navigation Satellite System (GNSS) position tracking for hydromorphological surveys, based on a comprehensive river restoration monitoring campaign. The aim of the research was to assess the method's suitability for efficient data collection in turbid, wadable rivers with sparse canopy conditions, and responds to the water management sector's increasing demand for efficient, low‐cost, and robust survey techniques. The methodological approach involved comparing manual, cross‐sectional water depth measurements to water depth estimations obtained by applying different interpolation methods to the continuous tracking data. The results demonstrate good agreement between both datasets (R2 = 0.77, RMSE = 0.13 m). When using a local standard deviation filter to remove noisy RTK‐GNSS measurements, estimation performance increased significantly (R2 = 0.96, RMSE = 0.06 m). The filter's influence on the hydromorphological habitat statistics mean water depth and coefficient of variation was limited but proved to be relevant for reach‐scale assessments of hydromorphological diversity. Based on a correlation analysis of >106 RTK‐GNSS position logs, we furthermore assessed the impact of tree canopy on RTK‐GNSS measurement accuracy and observed a strong influence within 6.5 m from the canopy border. Estimated accuracy deteriorated noticeably when canopy penetration exceeded 1 m, and accuracies >1 m were common beyond 4 m penetration. The study highlights the efficiency gains achieved with RTK‐GNSS tracking, and showcases its potential for hydromorphological surveys and streamgaging applications in challenging conditions, making it a promising alternative to traditional methods and remote sensing techniques.

This article aims to present the results of a bibliometric analysis of relevant literature and discuss the main research streams related to the topic of risks in drone applications. The methodology of the conducted research consisted of five procedural steps, including the planning of the research, conducting a systematic review of the literature, proposing a classification framework corresponding to contemporary research trends related to the risk of drone applications, and compiling the characteristics of the publications assigned to each of the highlighted thematic groups. This systematic literature review used the PRISMA method. A total of 257 documents comprising articles and conference proceedings were analysed. On this basis, eight thematic categories related to the use of drones and the risks associated with their operation were distinguished. Due to the high content within two of these categories, a further division into subcategories was proposed to illustrate the research topics better. The conducted investigation made it possible to identify the current research trends related to the risk of drone use and pointed out the existing research gaps, both in the area of risk assessment methodology and in its application areas. The results obtained from the analysis can provide interesting material for both industry and academia.
