Research in the Eltahir group is recognized for defining the role of land surface hydrology in shaping the climate system at regional scales. We seek to improve understanding of natural hydrologic phenomena, motivated by several environmental problems related to the impacts of deforestation, desertification and climate change. We develop state-of-the-art numerical models that are suited for simulation of climate processes at the regional scale. We test these models against satellite observations and archived data sets of hydrologic and atmospheric variables, as well as data collected in our own field campaigns.

Current research in the Eltahir group focuses on two general areas: (1) Regional climate studies of Africa, Southwest Asia and Southeast Asia; and (2) Development of a new class of environmental, hydrological and entomological models of infectious disease transmission (including malaria and dengue fever), which can be used for planning of environmental management interventions and prediction of the impact of climate change on disease transmission.

Past research investigations have included:

  • role of vegetation and soil moisture in the climate system; 
  • impact of deforestation on climates of the Amazon and West Africa;
  • predictability of hydrological floods and droughts in the Nile basin; and
  • impact of global climate change on the hydrology of the American Midwest agricultural region.
