野火会导致拒水，并消耗植物树冠、地表植物和凋落物，以及土壤中增强结构的有机物质。土壤水分、结构和入渗的变化会加速地表径流、侵蚀、泥沙输送和沉积。强降雨以及一些土壤和地形条件可能会导致陆上径流和渠道内泥石流。有机物质的矿化、根系吸收的中断和遮荫的丧失会通过增加溪流温度和营养物质浓度而进一步影响水质。在野火异常巨大和严重的地方，分水岭效应可能会受到负面影响。
Wildfire can cause water repellency and consume plant canopy, surface plants and litter, and structure-enhancing organics within soil. Changes in soil moisture, structure, and infiltration can accelerate surface runoff, erosion, sediment transport, and deposition. Intense rainfall and some soil and terrain conditions can contribute to overland runoff and in-channel debris torrents. Mineralization of organic matter, interruption of root uptake, and loss of shade can further impact water quality by increasing stream temperatures and nutrient concentrations. Where wildfires are unnaturally large and severe, watershed effects are likely to be negatively skewed.
