“…This RV reduction is important since it has great influence on the final flow energy, thus, on its capacity to detach and transport coarse soil particles and aggregates (Lambrechts et al, 2013). In bare soil (BHR), the exponential model was weakly adjusted to the data and this treatment had the lowest efficiency to reduce RV due to its low soil aggregate resistance, resulting in fast flattening and sealing of soil surface, which accelerate and increase runoff flow energy, as reported for this soil condition by Bertol et al (2010).…”

“…On-site sediment trapping measures can trap sediment and thus limit sediment export from agricultural fields Lambrechts et al, 2014;Mekonnen et al, 2014b). Grass barriers are among the many on-site measures that play a significant role in trapping sediments from overland flow (Ritsema, 2003;Blanco-Canqui et al, 2004;McKergow et al, 2004;Stroosnijder, 2009;Wanyama et al, 2012).…”

Abstract. Vegetation buffers like vegetative filter strips (VFSs) are often used to protect water bodies from surface runoff pollution from disturbed areas. Their typical placement in floodplains often results in the presence of a seasonal shallow water table (WT) that can decrease soil infiltration and increase surface pollutant transport during a rainfallrunoff event. Simple and robust components of hydrological models are needed to analyze the impacts of WT in the landscape. To simulate VFS infiltration under realistic rainfall conditions with WT, we propose a generic infiltration solution (Shallow Water table INfiltration algorithm: SWINGO) based on a combination of approaches by Salvucci and Entekhabi (1995) and Chu (1997) with new integral formulae to calculate singular times (time of ponding, shift time, and time to soil profile saturation). The algorithm was tested successfully on five distinct soils, both against Richards's numerical solution and experimental data in terms of infiltration and soil moisture redistribution predictions, and applied to study the combined effects of varying WT depth, soil type, and rainfall intensity and duration. The results show the robustness of the algorithm and its ability to handle various soil hydraulic functions and initial nonponding conditions under unsteady rainfall. The effect of a WT on infiltration under ponded conditions was found to be effectively decoupled from surface infiltration and excess runoff processes for depths larger than 1.2 to 2 m, being shallower for fine soils and shorter events. For nonponded initial conditions, the influence of WT depth also varies with rainfall intensity. Also, we observed that soils with a marked air entry (bubbling pressure) exhibit a distinct behavior with WT near the surface. The good performance, robustness, and flexibility of SWINGO supports its broader use to study WT effects on surface runoff, infiltration, flooding, transport, ecological, and land use processes. SWINGO is coupled with an existing VFS model in the companion paper (Lauvernet and Muñoz-Carpena, 2018), where the potential effects of seasonal or permanent WTs on VFS sediment and pesticide trapping are studied.
