- •
Surface temperatures were variable (averaging 238, 129, 327 °C at each burn).
- •
Heating durations were short (averaging 6 s for > 200 °C at the surface).
- •
High temperatures were associated with more water repellency, lower infiltration.
- •
Low intensity fire has heterogeneous hydrological and erosion impacts.
- •
Connectivity modelling is needed link point scale measures to larger scale impacts.
