- •
Agents of landscape disconnectivity are assessed for a semi-arid watershed in Brazil
- •
Controls on pulsed bedload transport are appraised
- •
Within-catchment variability in low, moderate and high magnitude events is shown
- •
ECA for low, moderate and high magnitude events are 34, 62 and 71% respectively
- •
Discontinuous sediment flux is important for watershed management in dryland settings
