The water protection zone of the Tsimlyansk reservoir was chosen as the object of research. The subject of the study was the assessment of the intensity of manifestation of dangerous coastal processes of the reservoir: abrasion-latency, erosion activity. A method for monitoring erosion processes in water protection zones of water bodies using a software and hardware complex based on unmanned aerial vehicles and GIS technologies has been developed and tested. The optimal type of digital elevation models has been determined for assessing the density of the erosion net-work, determining the types of banks and the intensity of manifestation of abrasion and landslide processes, measuring the morphometric characteristics of erosional landforms. The types of erosional landforms were determined and the zoning of the territory of the water protection zone of the Tsimlyansk reservoir was carried out according to the density of the erosional dissection of the relief. Studies have shown that the predominant erosional forms of the relief of the water protection zone of the Tsimlyansk reservoir are ravines and gullies. The maximum average value of the density of the erosional network of the relief within the boundaries of the administrative districts of the reservoir coast falls on the Surovikinsky district. In the Kalachevsky district, the maximum value of the density of the erosion network is noted within the water protection zone of the Tsimlyansk reservoir.

Protection Area

The nature and intensity of erosion processes are an important parameter for monitoring water protection area of water body. A technique, based on field and office studies, which were carried out with the use of unmanned aerial vehicles (UAVs) (Phantom 4 Pro and Phantom 4 Advanced), was worked out and the intensity of the manifestation of erosion processes in the water protection area of the Tsimlyansk reservoir was assessed (on the example of Dubovsky district). In our research, the comparative-geographic method was used. That allowed us very accurately to identify erosional objects on the ground, and to determine their morphological and morphometric characteristics. Cameral works processed the data obtained by using UAVs. The tools of the Agisoft Metashape Professional program and the tools of the ArcGIS program were used during the work. These programs make it possible, without labor-intensive instrumental field research, to draw up orthophotoplans for gullies and determine their areas, steepness of slopes, length and width of slopes, depth of gullies, make longitudinal and transverse profiles of gullies, measure the volume of gullies and a number of other parameters. This method gives us a complete picture of the gullying network within the water protection area. In addition, a comparison of survey materials for different periods makes it possible to identify trends in the development of individual erosional forms, as well as the entire gullying network within the water protection area as a whole.

The author pays a particular attention to solving the problems of monitoring the water protection zone of the Belgorod reservoir, especially the status and regime of use of water protection zones and changes in the morphometric features of water bodies or their parts and their water protection zones using UAVs. UAVs are considered depending on the design. The author made a conclusion about the necessary type of UAV for monitoring the condition of the coast and water protection zones of the Belgorod reservoir. The main technical characteristics of the recommended aircraft UAVs are presented in this paper as well.

In the article, the degree of displaying dangerous exogenetic geological processes (abrasion, landslide, erosion) of the Tsimlyansk Reservoir at the present stage of reforming its shores is assessed. A new original methodology for monitoring morphological and morphometrical characteristics of different shore types of the reservoir, using unmanned aerial vehicles (UAV) and Agisoft Photoscan tooling is proposed. For a number of shore sections of the Tsimlyansk reservoir, assessment of consequence for stirring up abrasion activity being expressed in stepping back the edge of shore steeps and reducing land fund is carried out. In the automated information system of water bodies state monitoring, a compulsory index is monitoring of erosion dismemberment. Methods to carry out erosion processes monitoring in water protection zones (WPZ) of water bodies using software and apparatus complex, created on the base of UAVs and GIS-technologies are developed and tested, an optimal type of digital elevation models (DEM) for assessing erosion network density is determined. Based on series of photographs carried out by UAVs by the DEMs and orthophotomaps, created using Agisoft Photoscan software, the relief erosion forms are determined. Morphometrical characteristics of the relief erosion forms are also measured, the erosion network density (K) for a number of plots in the water protection zones of the Tsimlyansk Reservoir coast is determined. In the protection zone of the Tsimlyansk Reservoir, comprehensive analysis is carried out, assessment of demographic load on the coastal area of the reservoir is conducted. Territorial zoning according to the degree of demographic load is carried out and it will allow in the future to organize planning timely measures for protecting coastal zones. The results obtained in the course of work allowed to make conclusions for the sections of the reservoir water protection zone most subject to anthropogenic activity and to propose a package of measures for its reducing.

Automated Information System

Determining value of erosion network density in the water protection zone is the compulsory index in the automated information system of water bodies state monitoring. The authors of the article developed and tested when studying the Tsimlyansk reservoir water protection zone recommendations for determining erosion network density by materials of distant inspections carried out using pilot-less aircraft (PLA) and tools of geographic information systems (GIS). In the article assessment of erosion network density for the Belgorodsk reservoir water protection zone carried out using given recommendations is presented. Such inspections are especially actual for the banks where regular observation benchmark network is lacking or they have low transport accessibility. Based on series of photographs made by pilotless aircrafts using Agisoft Photo Scan programme relief numerical models and orthophotomaps of the water protection zone are constructed. By direct and indirect signs position of tolwegs for the relief linear erosion forms of different orders—from furrows and grooves to brooks and small rivers. According to the recommendations developed by the authors, the water protection zone is divided into elementary segments and for every of them the value of erosion network density determined using GIS tools. Assessment of erosion network density showed that on the background of general low degree of the relief horizontal dismemberment for the Belgorodsk reservoir water protection zone the reservoir right-bank within Shebekinsky municipal region was distinguished noticeably. The erosion network density of this plot by 5–7 times exceeds the value of this parameter for the whole water protection zone of the reservoir. And only here relief erosion forms fully located within the water protection zone predominate noticeably, that is not characteristic for the rest part e the reservoir cost.

Unmanned aerial vehicles (UAV) have long been well established as a reliable way to construct highly accurate, up-to-date digital elevation models (DEM). However, the territories which were modeled by the results of UAV surveys can be characterized as very local. This paper presents the results of surveying the Sarycum area of the Dagestan Nature Reserve of Russia with an area of 15 sq. km using a DJI Phantom 4 UAV, as well as the methodological recommendations for conducting work on such a large territory. As a result of this work, a DEM with 0.5 m resolution as well as an ultrahigh resolution orthophotoplane were obtained for the first time for this territory, which make it possible to assess the dynamics of aeolian processes at a qualitatively different level.
