Abstract: 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.
