Restoring degraded landscape, managing soil and water resources are important for human well-being. Hillslope management and bioengineering, reforestation, and torrent control work using transverse structures, such as check dams and more recently open check dams, are becoming more common to mitigate soil erosion and torrential hazards. Such techniques are particularly important as they control the flux of water, sediments, nutrients, and other solutes from headwaters to downstream in any watershed management. The design and criteria of the check dams are also facing challenges due to complex hydrological, geological, and biological processes that affect water and sediment transport over a wide range of spatial and temporal scales. However, there are still lack of long term monitoring and sufficient understanding on the effects of soil and water conservation techniques on soil erosion processes, vegetation restoration, and torrential hazards control. Integrated watershed management also becomes increasingly crucial to mitigate the unprecedented impacts of environmental changes (e.g. climate, land-use changes). In this fourth consecutive year of organizing the session during EGU, we welcome studies that focus on soil conservation techniques from hillslopes to watershed scale. Any contributions to the understanding of soil erosion control and sediment transport management based on detailed field monitoring, high-quality laboratory works, mathematic models and effectiveness assessment methods are welcomed. In particular, we propose an approach to join and share scientific and technical studies from all around the world related to the legacy effects of check-dams and the potential of open check dams, highlighting the role of complex interactions between ecological elements, geomorphic processes and engineering activities.
