Rill Erosion - an overview | ScienceDirect Topics
网页Rill erosion is the detachment of soil particles by surface flow, and it occurs in a series of rills, which are small, parallel channels a few tens of millimeters wide. Location of rills is determined by soil surface microtopography. Interrill erosion occurs on interrill areas, which is the space between rills.
Advancements and challenges in rill formation ... - ScienceDirect
网页2021年1月1日 · Rill erosion is a small-scale but universally occurring phenomenon. Given its potential to concentrate into larger-scale erosion and its non-negligible contributions to soil loss, substantial research has been dedicated to understanding its processes.
Mathematical method for physics-based rill erosion process using ...
网页2022年3月21日 · This study presents a mathematical method to determine a physics-based rill erosion process derived from the feedback relationship of transport capacity and detachment capacity.
Characterizing the rill erosion process from eroded morphology …
网页2023年2月20日 · The specific objectives of this study were to 1) investigate the spatial characteristics of the rill morphology at different rill erosion stages; 2) characterize the changes in soil and water loss and potential sediment connectivity associated with rill erosion processes under different upslope terrace areas; and 3) assess the rill erosion ...
A review on rill erosion process and its influencing factors
网页2013年8月7日 · Rills are frequently observed on slope farmlands and rill erosion significantly contributes to sediment yields. This paper focuses on reviewing the various factors affecting rill erosion processes and the threshold conditions of rill initiation. Six factors, including rainfall, runoff, soil, topography, vegetation and tillage system, are discussed.
网页The new method provides a useful and ecient way to quantify rill erosion processes. Rill erosion is closely related to serious soil erosion and therefore reinforcing soil degradation and...
Rill Erosion and Soil Quality in Forest and Deforested ... - MDPI
网页2020年11月5日 · Rill erosion generally turns into gully erosion with severe environmental impacts. Changes in land use and human activities can have heavy effects in rill formation, particularly in forests subject to deforestation; soil morphology plays a significant role in …
Experimental evidence that rill-bed morphology is governed by …
网页2022年12月13日 · Past experimental work found that rill erosion occurs mainly during rill formation in response to feedback between rill-flow hydraulics and rill-bed roughness, and that this feedback...
网页rill erosion process into four sub-stages: 1) downward incision and horizontal development along the wetted perimeter of a rill; 2) local erosion by the scarps in a rill; 3) collapses of rill walls; and 4) lateral migrations of a rill. The viewpoints about the reasons for the initiation and development of rill erosion are inconsistent due to
Sheet and Rill Erosion - SpringerLink
网页2021年9月30日 · In this chapter, multiple sets of data collected from both closed (with artificial boundaries) and open plots (without artificial boundaries) are used to investigate soil and water loss caused by sheet and rill erosion. In particular, the effects of slope gradients...
