“…Only 12% of the active gullies occurred in cropland. Likewise, in Italy [98,99], more gullies have been observed in grazing lands than croplands [18,65]. Valley bottom gully incision seldom commences in forest lands.…”

Valley bottomland provides diverse agricultural and ecosystem benefits. Due to concentrated flow paths, they are more vulnerable to gully erosion than hillslope areas. The objective of this review was to show what caused valley bottoms gullies and to present deficiencies in existing rehabilitation measures. From the literature review, we found the following general trends: watershed characteristics determine location of valley bottom gullies; an increase in water transported from the watershed initiates the formation of gullies; the rate of change of the valley bottom gullies, once initiated, depends on the amount of rainfall and the soil and bedrock properties. Especially in humid climates, the presence of subsurface flow greatly enhances bank slippage and advancement of gully heads. Valley bottom gully reclamation measures are generally effective in arid and semi-arid areas with the limited subsurface flow and deep groundwater tables, whereas, for (sub) humid regions, similar remedial actions are not successful as they do not account for the effects of subsurface flows. To ensure effective implementation of rehabilitation measures, especially for humid regions, an integrated landscape approach that accounts for the combined subsurface and surface drainage is needed.

“…The most significant influence of the morphometric properties of the relief appeared to be the relationship between the slope and the vertical (normal) curvature of the relief. Based on the works of [41][42][43][44][45], slopes with a slope greater than 3 • show susceptibility to soil erosion. Therefore, our focus has been on the 3-12 • slopes.…”

Water erosion and its processes are the most widespread and serious degradation phenomena in Slovakia (occurring in about 37% of the agricultural land). Given the increasing use of precise land management, it is necessary to have more detailed databases, especially in erosion-accumulation areas. The aim of the research was to identify in detail the areas of erosion-accumulation processes induced by water erosion, which can be considered as highly heterogeneous. In the territory of the Nitra upland the field survey methodology and grid mapping were used, the results of which were verified through soil erosion models. The mapping was done at the topic level and was verified using the USLE and ERDEP soil erosion models in ArcGIS. A comparison of the results of the potential model and real field parameters of soil erosion in the Nitra upland enabled us to generate dominant factors, respectively identify areas prone to soil erosion, and provided a detailed database for precise farming. At the same time, the results became the basis for a review of the current classification by erosion endangered soils. Overall, the methodology is suitable as a basis for developing sustainable management proposals in agricultural land affected by soil erosion risk.

Ravines and gullies, a review about impact valuation

et al. 2023

View full text Add to dashboard Cite

Gullies and ravines affect human lives and the environment in many countries worldwide, however, few studies have assessed the impacts of the damage caused by these large linear erosions and clarified their influencing parameters. This work systematizes available information about the variables relevant to analyze the impacts of ravines and gullies on socioeconomic conditions and ecosystem services. Based on keyword searches performed in the Scopus, Web of Science and Dimensions databases, more than 120 articles from 27 countries were identified that addressed and valuated these different types of impacts. Although many studies discuss the impacts of ravines and gullies, few studies have performed valuations of these impacts. We compiled the impacts in urban and rural areas, considering the changes caused by ravines and gullies throughout a hydrographic basin. The results allowed for the elaboration of a theoretical model of the possible impacts of gullies and ravines and how they can be valued. The results demonstrate that the most significant impacts, according to the literature, are in South America, Africa, China and India, which are related to disordered land occupation. In some cases, the lack of capacity to respond to environmental and social problems aggravates the scenario and leads to significant losses. Implementing the evaluation is challenging due to the high number of different forms of possible impacts, in the short, medium and long term, related to environmental, economic and social changes.
