  abstract = {{T}errestrial vegetation has numerous positive effects on the main regulating services of agricultural channels, such as seed retention, pollutant mitigation, bank stabilization, and sedimentation, and this vegetation acts as a porous medium for the flow of matter through the channels. {T}his vegetation also limits the water conveyance in channels, and consequently is frequently removed by farmers to increase its porosity. {H}owever, the temporal effects of these management practices remain poorly understood. {I}ndeed, the vegetation porosity exhibits important temporal variations according to the maintenance schedule, and the water level also varies with time inside a given channel section according to rainfall events or irrigation practices. {T}o maximise the impacts of vegetation on agricultural channels, it is now of primary importance to measure vegetation porosity according to water level over a long time period rather than at a particular time. {T}ime series of such complex vegetation characteristics have never been studied using remote sensing methods. {H}ere, we present a new approach using the {S}tructure-from-{M}otion approach using a {M}ulti-{V}iew {S}tereo algorithm ({S}f{M}-{MVS}) technique to construct time series of herbaceous vegetation porosity in a real agricultural channel managed by five different practices: control, dredging, mowing, burning, and chemical weeding. {W}e post-processed the time series of point clouds to create an indicator of vegetation porosity for the whole section and of the surface of the channel. {M}owing and chemical weeding are the practices presenting the most favorable temporal evolutions of the porosity indicators regarding flow events. {B}urning did not succeed in restoring the porosity of the channel due to quick recovery of the vegetation and dephasing of the maintenance calendar with the flow events. {T}he high robustness of the technique and the automatization of the {S}f{M}-{MVS} calculation together with the post-processing of the point clouds should help in handling time series of {S}f{M}-{MVS} data for applications in ecohydrology or agroecology.},
