AB  - Gully erosion leads to the formation of deep and wide channels that increase the risk of soil loss, flooding, and
water pollution. In addition, this process reduces the productivity and viability of agricultural land and natural
ecosystems. Preventing gully erosion is critical for maintaining ecological balance and preserving natural resources in certain areas. This paper presents a methodology integrating remote sensing and nuclear techniques to
study gully erosion. The morphometric characterization of gullies using 360-degree camera photogrammetry was
introduced as a new method in erosion research. This approach aims to investigate the suitability of unmanned
aerial vehicle and terrestrial photogrammetry for modeling gullies, to study the variability of erosion processes in
gullies at a small scale, and to compare the differences in erosion intensity between nearby gullies. The study’s
objectives include identifying the effective and economical method for gullies monitoring and providing a
starting point for controlling and safeguarding gullies. Mainly erosion process was detected in the studied gullies,
while deposition was identified at only 2 out of 39 sampling locations. The results showed an average soil
redistribution rate of 16.2 t ha− 1 yr− 1 and coefficients of variation of 32%, 59%, and 91% for three investigated
gullies. It was determined that aerial photogrammetry methods were not practical under the conditions prevailing in the study area. Highly detailed 3D models of the gullies were created using 360-degree photogrammetry. It was confirmed that the micro-relief obtained by photogrammetric modeling is an essential contribution
to erosion research. The 360-degree camera photogrammetry serves as a reliable tool for analyzing the
morphology of gullies and, in perspective, tracking changes in gully systems over time or monitoring the
effectiveness of the applied protection measures.

AB  - The gully erosion is one of the most significant land degradation processes. Although gully erosion significantly threatens agricultural productivity and natural ecosystems, European land management strategies frequently need more reliable data on environmental conditions governing this process. This study presents a methodology that integrates remote sensing and nuclear techniques for examining gully erosion (Đokić et al., 2023). It introduces a novel approach to erosion research by employing 360-degree camera photogrammetry to characterize gullies morphometrically. The main objectives of this approach are to evaluate the applicability of unmanned aerial vehicles and terrestrial photogrammetry for modeling gullies, to study small-scale erosion processes within gullies, compare erosion intensity between adjacent gullies, and determine the most effective and cost-efficient method for monitoring gullies. A total of 39 soil samples were taken in three studied gullies. The results revealed an average soil redistribution rate of 16.2 t ha−1 yr−1 and coefficients of variation of 32%, 59%, and 91% for the gullies. The estimated erosion rate varies from a minimum of 0.1 t ha−1 yr−1 to a maximum of 34.3 t ha−1 yr−1. Soil deposition was identified at only two sampling sites, 1.1 and 2 t ha−1 yr−1. Highly detailed 3D models of the gullies were created using 360-degree photogrammetry. The micro-relief obtained through modeling proved to be an essential aspect of advanced erosion research.

AB  - Hilly terrains characterized by the looseness of the surface soil layer and the slope of the topographic surface are subjected to diverse erosion processes, which could greatly impact forest management. An erosive process was identified along the unstable slopes in most of the Crveni potok catchment in the southeastern part of Serbia. The results of this study indicate two erosion types of variable intensity, dominated by weak and moderate erosion, while severe erosion is identified at several locations. Water pressure in the pores of loose soil in the Crveni potok catchment generates gully erosion in parts of the catchment that are geologically predisposed by the composition of the parent substrate. The paper discusses the factors influencing gully erosion, such as soil density, the slope of the topographic surface, rainfall (precipitation amount, annual distribution), and vegetation characteristics. The set of used methodologies, including remote sensing, nuclear, and geospatial ones, provided an integrated assessment of factors affecting erosion in unstable forest areas. The soil erosion rates in the study area are estimated from inventories of fallout radionuclide 137 Cs using conversion models. Airborne photogrammetry, terrestrial Structure-from-Motion 360-degree camera photogrammetry, and Terrestrial LiDAR Scanning (TLS) are used to model complex geomorphological features of forest terrain. These techniques are found to be convenient for the quantification of the existing state of erosion (length, width, volume, and density of the gully systems) in the forest gullies. The remote sensing techniques provided an insight into the physiographic characteristics of the studied area important for determining its parts affected by erosion. The models obtained using different techniques are compared, techniques are evaluated, and their advantages and disadvantages are pointed out. This approach enables the identification of priority targets for soil conservation and site-specific remediation measures to foster sustainable forest management.
