Floodplains are complex systems which include a wide number of socio-economic activities like agriculture, freshwater fisheries, electricity from power plants and others. They have often highly dynamic property, due to the alternation of fluvial processes, floods, and ongoing sediment transport, as well as of environmental specifics and natural or anthropogenic processes. In the context of the investigation of soil pollution with heavy metals in the riverine floodplains, the availability of geomorphological maps a...

Two independent sources of information on intra-field heterogeneity of crop productivity were investigated. Field verification of both sources of information was carried out. The first source is a map of stable intra-field heterogeneity of soil fertility. This source is obtained by analyzing large satellite data for decades (1984 - 2020). The second source is a crop yield map for a particular year. The map was obtained according to the results of yield measurements from the sensors of the John Deere combine. A map...

In recent years, a range of UAV photogrammetry applications, such as long-range corridor mapping, has increased significantly [4]. However, in photogrammetry linear configuration of the flight is considered to be problematic, due to geometric distortions creating ?bowl effect? and a high correlation between focal length and flight altitude. Thus, it is important to investigate how factors like georeferencing method and camera calibration affecting final accuracy. The aim of the article is to determine if the direc...

The research is aimed at studying the quantitative laws of the morphological pattern dynamics for alluvial plains. Basing on the random process theory - the renewal process theory, we substantiate that in the course of the development despite constant changes such as generating new packages, erasing old packages, changing of the number of a package, some features of the morphological pattern remain the same. They are the length distribution of the arrows for the preserved (non-erased) package fragments, the durati...

The Karabai tract was selected as an object of study, which is a monoculturally planted pine forest with predominance of Rhinus sylvestris L. and P. pallasiana D. Don, located on the territory of Kherson region, Ukraine. This forestry is known for one of the largest forest fires in Ukraine, which...

The Shchuchinsko-Borovskaya system, consisting of seven large lakes, was studied. Lakes of tectonic origin are located at different absolute levels within the granite massif. The water in the lakes is fresh, less often brackish, and previously has been widely used for agricultural and drinking purposes. Based on monitoring data and analysis of a long-term series of satellite images over the past 30 years, a significant decrease in the level of the lakes and water resources has been revealed. This has affected the ...
