“…Vegetative filter strips (VFS) play an important role in reducing the impact energy of rainfall, reducing the detachment capacity of overland flow, trapping sediment, and controlling non‐point source pollution (D. Pan et al, 2018; Wainwright et al, 2008; F. Yang, Yang, Li, & Cao, 2015). Therefore, VFS have been widely used as best management practices (Blanco‐Canqui, Gantzer, Anderson, Alberts, & Thompson, 2004; Carluer, Lauvernet, Noll, & Munoz‐Carpena, 2017; Reichenberger, Sur, Kley, Sittig, & Multsch, 2019). The sediment‐trapping effect in a VFS is mainly caused by the resistances of vegetation stems, litter, bed micro‐topography, and grain, which consume energy and reduce the sediment transport capacity of overland flow (Comiti, Cadol, & Wohl, 2009; Luo, Pan, & Liu, 2020a; C. Pan, Ma, Wainwright, & Shangguan, 2016; Prosser, Dietrich, & Stevenson, 1995).…”

Particle selectivity plays an important role in clarifying sediment transport processes in vegetative filter strips (VFS). 10-m long grass strips at slopes of 5 and 15 were subjected to a series of sediment-laden inflows experiments with different particle sizes to investigate the sediment transport and its response to overland flow hydraulics. The inflow sediments came from local soil, riverbed sand, and mixed, with median particle size d 50 of 39.9, 207.9 and 77.4 μm, respectively. Three independent

“…The Vegetative Filter Strip Modeling System (VFSMOD) is a field‐scale, mechanistic, storm‐based numerical model that has been used in the design of VFSs (Carluer et al, ; Munoz‐Carpena & Parsons, ). The VFSMOD simulates the hydrological and sediment transport processes in VFSs (Munoz‐Carpena & Parsons, ; Pan et al, ) and reliably matches field observations in most cases (Carluer et al, ; Munoz‐Carpena & Parsons, ; Reichenberger & Sur, ).…”

Vegetative filter strips—Effect of vegetation type and shape of strip on run‐off and sediment trapping

et al. 2018

Vegetative filter strips (VFSs) are a common type of off-site method used to enhance the sustainability of catchment systems by promoting desirable soil and landscape functions. The transport of water run-off and sediment to downstream reaches can be restricted by VFSs in the flow path. The adoption of VFSs is increasing because they have been demonstrated to be effective for trapping run-off and sediment. Thus, an optimized design procedure for developing VFSs is required. To further understand the roles of both vegetation type and geometric size in the design of VFSs, global sensitivity analysis (GSA) within the Vegetative Filter Strip Modeling System was conducted using a traditional elementary effect test and a novel density-based method called PAWN. The analysis involved both a uniform and a concentrated flow scenario.The GSA outcomes indicated that the inputs related to vegetation type were vital for the VFS design, especially in terms of the run-off reduction function of the VFS, irrespective of the scenario that was used. The vertical saturated hydraulic conductivity was the main input responsible for the influence of vegetation type. The inputs related to vegetation type had limited influences on the sediment trapping performance of the VFS, which was shown to be mainly controlled by the length of the VFS. The role of vegetation type in the design of VFSs must be fully considered, especially in cases in which VFSs are established primarily for flood control or run-off reduction purposes.

“…These compounds contribute 1% and 23% tot total DP and PP transport, respectively. The borders and interrow area of the orchard were covered with grass, which has a reducing effect on soil erosion and a filtering and buffering effect on the transport of pesticides (Muñoz-Carpena et al, 2018;Reichenberger et al, 2019;Yu et al, 2019). During field observation, no signs of erosion were recorded from the apples.…”

Agriculture on sloping lands is prone to processes of overland flow and associated soil detachment, transportation, and deposition. The transport of pesticides to off-target areas related to runoff processes and soil erosion poses a threat of pollution to the downstream environment. This study aimed to quantify transport of pesticides both dissolved in water and in the particulate phase in transported sediments. Particulate phase transport of pesticides on short temporal time scales from agricultural fields is scarcely studied. During two growing seasons (2019 and 2020) rainfall—runoff events were monitored in a catchment of 38.5 ha. We selected 30 different pesticides and one metabolite based on interviews with the farmers on the application pattern. Concentrations for these 31 residues were analyzed in runoff water (dissolved phase–DP) and sediment (particulate phase–PP) and in soil samples taken in the agricultural fields. In all runoff events active substances (AS) were detected. There was a clear difference between DP and PP with 0–5 and 8–18 different AS detected in the events, respectively. Concentrations in PP were higher than in DP, with factors ranging from 12 to 3,700 times. DP transport mainly occurs in the first days after application (69% within 10 days), and PP transport occurs over the long term with 90% of transported mass within 100 days after application. Potato cultivation was the main source of runoff, erosion, and pesticide transport. Cereals and apples with grassed inter-rows both have a very low risk of pesticide transport during overland flow. We conclude that for arable farming on sloping lands overland transport of pesticide in the particulate phase is a substantial transport pathway, which can contribute to pollution over longer time periods compared to transport in water. This process needs to be considered in future assessments for pesticide fate and environmental risk.
