Dynamics of Erosion and Deposition in a Partially Restored Valley-Bottom Gully

Gullies are sources and reservoirs of sediments perform as efficient transfers runoff sediments. In recent years, several techniques technologies emerged to facilitate monitoring gully dynamics at unprecedented spatial temporal resolutions. Here we present a detailed study valley-bottom in Mediterranean rangeland with savannah-like vegetation cover that was partially restored 2017. Restoration activities included check dams (gabion weirs fascines) livestock exclosure by fencing. The specific objectives this work were: (1) analyze the effectiveness restoration activities, (2) erosion deposition before after using high-resolution digital elevation models (DEMs), (3) examine role micro-morphology on observed topographic changes, (4) compare current channel previous studies conducted same area through different methods spatio-temporal scales, quantifying medium-term changes. Topographic changes were estimated multi-temporal, DEMs produced structure-from-motion (SfM) photogrammetry aerial images acquired fixed-wing unmanned vehicle (UAV). performance satisfactory control erosion. Check effective favoring sediment reducing lateral bank Livestock promoted stabilization headcuts. implemented measures increased notably deposition.
