H13S:
Understanding the Extent and Impacts of Land Use/Land Cover Change on Hydrology II


Session ID#: 10640

Session Description:
Land-use and land cover change have the potential to drastically alter the hydrologic cycle and alter the spatiotemporal movements of water resources. The emerging challenges of land system changes from a natural resource perspective are (1) Observing/estimating land-use and land-cover change and (2) Quantifying/predicting subsequent hydrologic impacts. This session invites submissions that use emerging geospatial techniques to quantify hydrologically-relevant landscape change and/or examine land-use and land-cover impacts on: (i) Regional water balance/water resource change (ii) Changing land-atmosphere water fluxes (iii) Regional climate/drought characteristics (iv) Land degradation and subsequent hydrological change.  We also welcome studies exploring hydro-chemical fluxes and those dealing with uncertainty in selection of land cover datasets, assimilation of observed vegetation characteristics, modeling, or statistical methods.
