Two Ecohydrology Research Assistantships at Arizona State University in Tempe, AZ. Two M.S./Ph.D. assistantships in hydrology/water resources are available starting in the Spring or Fall 2010. The assistantships can be either in the School of Sustainable Engineering and the Built Environment or the School of Earth and Space Exploration. The two projects will focus on: (1) Ecohydrology of grassland-shrubland transitions to identify controls of hydrologic connectivity at multiple scales; and (2) Seasonality effects on the ecohydrology of the North American monsoon region at the catchment to regional scale. Each assistantship will require data collection, numerical modeling and data synthesis efforts in field sites in Arizona, New Mexico or Sonora, Mexico. Preference will be given to highly-motivated Ph.D. students with strong quantitative skills. For inquiries, contact Prof. Enrique R. Vivoni (vivoni@asu.edu).
