The Impact of Tree Planting on Infiltration Dependent on Tree Proximity and Maturity at a Clay Site in Warwickshire, England

Nathaniel Revell et al.

Summary: This study investigates the impact of tree planting on infiltration and finds that proximity to trees and season have a significant influence. Infiltration rates are higher at a closer distance to trees and in summer compared to winter. There is no evidence of a relationship between infiltration and tree maturity at the study site.

Quantifying the effects of grass distribution patterns on the relative hydrodynamic parameters of overland flow

Hongyang Zhang et al.

Summary: The distribution pattern of grass plays a crucial role in soil erosion and hydrodynamic characteristics of overland flow. Different patterns have different effects on flow discharge and slope gradient. The vertical strip pattern and chequerboard pattern are the most effective in retarding flow. By parameterizing the grass distribution pattern, prediction models for relative flow velocity and relative Froude number can be established, which can inform optimal designs for water and soil conservation.

Experimental study on the effect of simulated grass and stem coverage on resistance coefficient of overland flow

Youdong Cen et al.

Summary: Vegetation plays a significant role in preventing desertification, conservation of soil and water. However, there is still uncertainty regarding the mechanisms of flow resistance caused by different vegetation covers. This study investigated the influence of synthetic grass and stems on overland flow resistance and found that the unit discharge is the key driving factor for the transition from laminar to transitional flow. A critical coverage threshold was identified, and the relationship between resistance coefficient and Reynolds number was specifically linked to each vegetation coverage. The linear superposition approach is not applicable to overland flows, and a model was developed to accurately predict flow resistance.

Response of interrill erosion to flow parameters of sand loess in regions with high and coarse sediment yields

Pu Li et al.

Summary: The study found that in the Loess Plateau, the interrill erosion mechanism of Shenmu soil can be classified into two types: detachment-limited erosion in the initial rainfall phase and transport-limited erosion in the subsequent rainfall, or transport-limited erosion throughout the entire rainfall. Among various flow intensity parameters, stream power was found to be the most reliable for predicting interrill erosion rate, with a satisfactory coefficient of determination (R-2). However, the erosion rate model based on stream power showed low prediction accuracy for the two types of soil. Additionally, a general flow intensity parameter was derived to predict interrill erosion rate, with a high model efficiency of 0.94.

Flow Resistance in Open Channel Due to Vegetation at Reach Scale: A Review

Antonino D'Ippolito et al.

Summary: This paper explores the impact of vegetation on water energy losses in riverbanks and flood areas, with computational models incorporating resistance coefficients and roughness evaluations. It reviews classical approaches and recent advancements in analytical methods for both rigid and flexible vegetation, highlighting drag coefficients and resistance laws. The study also briefly discusses the use of 3D numerical methods for assessing turbulence characteristics and the transport of sediments and pollutants, as well as the application of remote sensing for mapping riparian vegetation.

Flow dynamics and sediment transport in vegetated rivers: A review

Wen-xin Huai et al.

Summary: The significance of riparian vegetation on river flow and material transport is unquestionable. Adjustments to conveyance laws, sediment erosion and deposition, and element cycling are necessary to accommodate aquatic plants. The growth of vegetation is influenced by fluvial processes and river morphology, making the study of these interactions crucial for river restoration.

Geomorphic natural hazard on loess terrain: expansion on the gully sidewall

Yulei Ma et al.

Summary: The study shows that gravity erosion is the main driving force behind gully sidewall expansion, and the most significant factors affecting the change in slope gradient of the gully sidewall and retreat rate of the gully shoulder line are rainfall duration and intensity.
