Abstract:
... Monoculture farming pollutes the environment by increasing the use of inputs, accelerating soil erosion, polluting water resources, raising carbon level in the atmosphere, and decreasing biodiversity. Therefore, farmers are advised to implement diversified farming systems such as crop rotation. However, crop rotation, i.e., planting more than one crop in the same field over a given year, may also ...

Abstract:
... Increases in pore water pressure affect the effective stress state of loess soil, resulting in deformation and even soil erosion. However, it is still unclear how the mechanical behaviours and microstructures of soil are influenced by the rate of increase in pore water pressure (RIPWP). To better understand the mechanical failure process and properties of soil under different RIPWPs, a series of c ...

Abstract:
... Aside from the many services that soil provides, it also stores water and makes it available to crops, which is critical for food security. However, the necessity of further studies for overcoming the existing gap in relation to the role of soil in the water, energy, and food nexus system has been preoccupying the experts and specialists around the world for some time. In this sense, the balance b ...

Abstract:
... Soil erosion strongly threatens the sustainability of natural ecosystems over the world, especially in the Loess Plateau in China, where has suffered severe soil erosion along with extensive land reclamation and deforestation from the 1950s to the 1970s. The large-scale vegetation restoration practices are supposed to be effective for reducing soil erosion, but the quantitative evaluation of soil ...

Abstract:
... Subsurface water flow, considered as a specific hydrological condition, can couples with overland flow, which likely lead to notable effects on soil detachment process in rills. Clarifying the change in soil detachment rate under different subsurface flow conditions is beneficial to understand the mechanisms of soil erosion and improve process-based erosion model. In this study, the maximum sedime ...
... We responded to the comment by Chen and Huang (2022). We found that the formula of R factor originally quoted was wrong. We replaced it with a new formula suitable for the Loess Plateau, and corrected the errors in the article. ...

Abstract:
... Process‐based model ling has long been used as a well‐suited tool to simulate soil erosion. Despite a large number of scientific articles that emphasize the role of compacted tramlines for soil erosion and surficial nutrient transport, no study exists that integrates these artificial structures into process‐based modelling at catchment scales. Thus, this study aims to quantify the effects of traml ...

Abstract:
... Soil erosion has been recognized as a significant environmental issue in the United States for over 200 years. Numerous attempts have been made to predict and quantify the phenomenon, yet significant issues remain that hinder the accuracy and effectiveness of such models. This article describes the application of the new generation Unit Stream Power Erosion and Deposition (USPED) model that estima ...
... The earth observation data and CMIP6 models were used to predict plausible soil loss from the Ghaghara river basin. The decadal prediction of soil loss (28.64 ton/ha/year) was found high for SSP585 of CanESM5 during 2015–2025. However, the lower value was reported as 21.71 ton/ha/year for SSP245 of MRI-ESM2-0 during 2035–2045. The century level future rainfall erosivity factor was found lowest for ...

Abstract:
... Soil erosion is the most important soil degradation process threatening semi-arid and arid areas. In this study, the change in the RUSLE-K soil erodibility values due to changed climatic conditions over a 10-year period was used as a tool to investigate soil erosion potential with Sequential Gaussian Simulation (SGS) method in the Mogan catchment in Turkey. For this purpose, soil erodibility value ...
... Soil erosion by water from arable land poses a serious threat to on-field agricultural productivity and the wider environment through off-site damage. Multiple studies show that climate change will worsen the impacts of soil erosion in various regions. However, these studies are limited by (1) the lack of any thorough evaluation process in applying climate scenarios to drive soil erosion models, a ...

Abstract:
... Sediment transport rates are widely used in studies of soil erosion, hydrological simulation, and regional ecological assessment. Although traditional field hydrological stations can provide a global sediment transport rate for observation areas, quantifying sediment transport rates in space is still challenging. This study presents a work frame for monitoring and modeling sediment transport in sp ...

Abstract:
... The transport of particulate organic carbon (POC) through rivers from land to sea affects the redistribution of global organic carbon. However, because of the limitation of the quantity and quality of monitoring data, the POC magnitude, scale and global distribution pattern of land-sea migration are still not well understood. Therefore, based on an updated GEMS-GLORI database and other reanalysis ...

Abstract:
... PURPOSE: In recent decades, soil erosion has been recognized as a serious environmental problem in many countries of the world and the impacts of climate change have focused attention on potential changes in erosion rates that could further increase such problem. These impacts are documented by a general decrease of annual precipitation and a corresponding increase in the number of heavy rainfall ...

Abstract:
... Cover Crops (CC) are increasingly appreciated in vineyards because they can provide ecosystems services, such as preventing soil erosion and compaction, increasing soil organic matter or, controlling weeds. Many species from different botanical families can be used depending on the final purpose of the CC, but their successful establishment in Mediterranean semiarid conditions of NE Spain can be c ...

Abstract:
... PURPOSE: The ¹³⁷Cs tracing technique has strong potential to monitor and evaluate soil loss in complex karst geomorphology regions. However, ¹³⁷Cs might move downward with soil fine particles under adequate rainfall conditions. This is critical because it directly affects accuracy of using the ¹³⁷Cs conversion model to evaluate soil erosion. Thus, the objectives of this study were to explore wheth ...

... AIMS: With the wide application of ⁷Be (Beryllium-7) in soil erosion investigations, retention and interception of ⁷Be by vegetation plays an important role in documenting soil ⁷Be redistribution, with a large impact on the interpretation of ⁷Be measurements. However, the dynamic and temporal changes in plants and the relationship with soil ⁷Be concentration remain unclear, and the significance of ...

Abstract:
... The study of gully characteristics is one of the most effective ways to explore the loess landform development in the Loess Plateau of China. However, current studies mostly focus on gullies’ overall characteristics and ignore the different composition of the whole gully system. Therefore, a new perspective is provided in this paper for exploring loess landform development from the population char ...
