Web1 May 2015 · A common cause of erosion on hillsides with farming terraces is the collapse of stone walls and mass soil movement ( Fig. 6 ). On abandoned terraces, Freppaz et al. (2008) observed that such collapses started to be widespread after 12–15 years and leave the terrace riser completely unprotected and bare. Web20 May 2024 · At the same time, the downcutting and lateral erosion of the flowing water are strong, while the erosion resistance of the river terrace risers is weak.
