This paper aims to assess the trend of river morphological evolution and changes in the Danube riverbed sector, i.e., Ceatal Izmail, using GIS techniques. The sector is located on the Danube at Mile 43, where the river branches into Chilia and Tulcea tributaries. Therefore, three monitoring topo-bathymetric profiles (2018 and 2019) were performed on Danube (Mm 43), Chilia (Km 114) and Tulcea (Mm 42.5), under circumstances of high and low water levels. On the Danube (Mm 43), an asymmetry of the valley (right bank) ...

Smart farming usually includes elements of precision farming. In turn, in precision farming, differentiated application of chemicals is often used. It can be realised using two types of different techniques: by installing of vegetation state sensors on agricultural machinery or on the basis of task maps. Task maps are formed, as a rule, from third-party independent data sources, prior to the entry into the field of the machinery of differential impact on agricultural land. The aim of our work is the comparative an...

Modern professional geographic information systems (GIS) include a wide range of well-tuned powerful algorithms for processing and analyzing spatial data, but their use is hampered by the specifics of the information environment in which the GIS data operate. At the same time, web technologies can provide an information environment that will allow users to access GIS software from anywhere in the world. The integration of GIS and web technologies provides greater opportunities for collecting, accumulating and proc...

The issue of suitability the territory for agricultural use has always been an important for rational land use organization. One of the factors in this assessment is the slope of the territory as an indicator of its suitability for growing crops. For instance, in Ukraine, the law prohibits plowing slopes steeper than 7 degrees. Traditionally, the method of assessing the suitability of the territory for agricultural use includes several stages: 1) identification of zones with different slope steepness and degree of...

Our paper describes a case study, on a 27 km-long section of the Moldova River in Romania, on which floods often occur. Floods are some of the most disastrous phenomena caused by combined factors: atmospheric and hydrological with significant repercussions on the environment, with great material damage and loss of life. According to this application, GIS technology is a remarkable solution that can solve rationally, intelligently and efficiently the increasingly difficult problems related to these phenomena, to th...

For the territory of the Crimean Peninsula, no morphometric analysis of the entire terrain relief has been carried out using common methodology. This makes it impossible to compare the results obtained. When performing a morphometric analysis, researchers pay inadequate attention to the choice of an operational unit to be studied. This is the reason why the results obtained using the same materials differ significantly. Therefore, the purpose of the work was to conduct a morphometric analysis of the Crimean terrai...

The ecological movement emergence in the Federal Republic of Germany and its subsequent, rapid politicization, on which wave the Green Party is institutionalized, was due to a reasons complex set for socio-economic, political and spiritual origin, passed through the relationships existing system prism between human society and the environment. These reasons? combination initially gave the ecological movement a specific features number, which presence greatly complicates its socio-political essence knowledge, since...
