H24B:
Ecohydrology of Disturbed Environments II


Session ID#: 10627

Session Description:
Climate and land-use impacts on disturbance regimes are driving major changes in linked ecologic-hydrologic systems from regional to global scales. Landscape disturbance events include vegetation dieback, wildfire, invasive species encroachment, extreme hydrometeorology, and land-use change.  This session focuses on ecohydrological processes and shifts related to disturbed landscapes, including dieback, encroachment, vegetation type conversion, and impaired vegetation recovery.  Research topics include (but are not limited to): 1) effects on hydrologic cycling and water storage, 2) alterations to biogeochemical cycles, and 3) recovery timescales and trajectories of geomorphic and ecohydrologic processes.  We invite work reaching across spatial scales from plot to global in scope and applied techniques from laboratory, field, and numerical modeling investigations.
