Utilization of Signal Global Navigation Satellite System (GNSS) for Meteorological [PDF]
International Journal of Environment, Agriculture and Biotechnology, 2021 In this study, I show that microwave signals emitted from satellites and received by the GNSS system can be utilized for meteorological purposes, such as heavy rain in Indonesia, using open-source software goGPS. Comparison of the gradient of the North and East atmospheric delays between goGPS, IGS, and UNR. The correlation of the results of goGPS with

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring
River Research and Applications, EarlyView.ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam
River Research and Applications, EarlyView.ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.
