Wildfire is a landscape‐scale disturbance that changes the rate and magnitude of many earth surface processes. The impacts of fire on earth surface processes can vary substantially from place to place depending on a variety of site‐specific conditions, including topography, fire severity, regional climate, vegetation type, and soil type. This variation makes it critical to bring together scientists studying fire and earth surface processes from different perspectives and in different parts of the world. This special issue pulls together studies that present cutting‐edge research addressing the geomorphic and hydrologic impacts of wildfire across a range of spatial and temporal scales, including advances in managing some of the negative, short‐term effects of wildfire. Contributions to this collection cover the following themes: insights from field measurements, sediment and carbon redistribution, insights from process‐based modeling, post‐fire debris flows, and post‐fire mitigation. The work presented in this special issue will help to advance the capabilities of scientists and land managers to observe, simulate, and anticipate changes to earth surface processes following fire.
