H34B:
Disturbance Hydrology: Assessing the Impacts of Abrupt Landscape Changes on Watershed Hydrology III


Session ID#: 10554

Session Description:
Environmental changes associated with human and natural disturbances have far reaching and long-lasting impacts on watershed response. Abrupt changes to land cover and catchment structure resulting from vegetation clearing, natural resources extraction, and extreme events such as volcanic eruptions, earthquakes, floods, and landslides all alter hydrological processes. Whereas research in watershed hydrology has focused largely on undisturbed settings, arguably the majority of terrestrial landscapes are disturbed, either episodically or regularly. Despite an increasing frequency of disturbances associated with population growth and climate change, our understanding of how disturbance regimes influence flow paths, rainfall partitioning, and storage dynamics remain limited. The goal of this session is to share recent scientific findings about the role of disturbances as the primary driver of hydrology, hydrologic regime, hydrogeomorphic processes, and hydrologic variability. We welcome investigations across spatial and temporal scales that use field measurements and experimentation, data analysis, and hydrologic modeling.
