Droughts Dynamics under the Impacts of Climate, Vegetation and Their Interactions
Session ID#: 83575
Session Description:
The initialization, expansion and recession of drought are controlled by the climate variations, vegetation dynamics and their interactions in both natural and managed hydrological-systems. For instance, Nature/Human-decision making influences on the hydrologic-regimes results in hydrologic variations which impose tangible impacts on the climate-soil-vegetation interactions. Likewise, vegetation nonlinearly regulates the propagation of climate variability through hydrologic-systems. Understanding of drought-processes within complex hydrological-systems can be gained either by focusing on individual catchments with detailed account for human-influence, ecological and hydrologic processes (Newtonian) or emergent nature/human induced spatial/temporal patterns of ecological/hydrological behaviors from a population of catchments (Darwinian). Corresponding research tools can range from simplistic functional relations to sophisticated physically-based eco-hydrological models. This session invites contributions on data analysis and modeling of, i) drought propagation from atmosphere to soil moisture then to rivers in natural/managed hydrologic-systems, ii) the linkage between hydrological and ecological droughts in natural/managed systems, and iii) Ecohydrology of water-limited ecosystems.
