Two main effects of wildfires on hydrology are increased runoff and decreased water quality. After a wildfire, there is a greater potential for flooding, erosion, and transport of sediment and increased nutrient and metal concentrations to public water supplies, leading to higher water treatment costs and potential to impact water availability, as well as stream habitat degradation. The StreamStats Fire-Hydrology workflow provides actionable intelligence to stakeholders in the wildland fire, local government, and science communities in a more streamlined fashion. The application integrates watershed delineation capabilities with fire perimeter and burn severity layers to calculate post-burn peak flows, as well as provides stream tracing to identify affected streams and stream gages.
Basic functionality covers the contiguous 48 states. Equations and basin characteristics are limited to source data availability. Behind the scenes, National Land Cover Data covers the whole conterminous US, but Atlas 14 precipitation frequency data is unavailable for the Pacific Northwest.
