- Abstract:
-
The layout of dam system project in Niejiahe Watershed took the existing key projects as skeleton. All levels of channel laid small and medium warping dams and key projects from upstream to downstream, as well as emplaced rainfall, sediment retaining and transport monitoring sites in its typical warping dam of demonstration dam system. The monitoring results showed that dam system raised the erosion baseline, stabilized the gully, controlled gully bed scour and gully bank expansion, and enhanced soil and water conservation capacity, so that the project could block sand, control soil erosion, protect farmland, and reduce sediment into the Yellow River effectively, which played an important role in ensuring the safety of downstream river.
