SSS2.9/GM6.11Seeking a better understanding of gully erosion (co-organized)
|Convener: Carlos Castillo | Co-Conveners: Javier Casalí , Rafael Giménez , Robert Wells , Erkan Istanbulluoglu , Johannes B. Ries|
Gully erosion is, undoubtedly, one of the major processes of land degradation worldwide, producing sizeable economic losses in agricultural and urban landscapes. It is also an important process for transient landscape evolution. Being a highly complex phenomenon, this type of soil erosion process poses challenging questions to the scientific community. There still exist knowledge gaps that need to be addressed, despite recent advances. This session intends to stimulate discussion and knowledge transfer among researchers seeking new perspectives to understand gully erosion. The main topics of the session will be:
1. Monitoring: Strategies and methodologies for improved data collection.
2. Controlling factors: How can anthropogenic activities (e.g., tillage and road construction) effect gully erosion processes? Differences between natural and anthropogenic gully erosion characteristics.
3. Modelling: How can models and/or prediction technology improve the knowledge base and impact conservation design?
4. Processes: Gully specific flow hydraulic and sediment transport mechanics.
5. Integration: Interaction between gully erosion and other land degradation processes.
6. Gully restoration: Cost-effective measures and tools for gully control.
