Assessing SWAT model sensitivity to fire-related soil organic carbon changes using digital soil mapping products

"Biomass burning is one of the main causes of carbon loss in the soil and could lead to increased erosion and runoff. SWAT models can be used to predict long-term impact of land use change on catchment flow and water quality as well as testing “what-if” scenarios. Fire in water catchments needs to be dealt with on a case-by-case basis so land managers can chose the best options to increase the mass of carbon in soil and retain water in the system. The availability and application of suitable models to test changes in water quality and quantity is essential to provide better management options." - Dr. Felipe Aires NSW National Parks and Wildlife Service
