Science and Products
Characterizing high-resolution soil burn severity, erosion risk, and recovery using Uncrewed Aerial Systems (UAS)
The western United States is experiencing severe wildfires whose observed impacts, including post-wildfire floods and debris flows, appear to be increasing over time.
Identifying the Risk of Runoff and Erosion in Hawaiʻi’s National Parks
Haleakalā National Park (HNP) and the surrounding landscape spans many different land cover types, some of which are undergoing vegetation changes that can reduce the amount of water that infiltrates into soil. Decreased soil infiltration can lead to the erosion of terrestrial habitats, increases in the amount of sediment entering aquatic habitats, and flooding of downstream areas as runoff incre
