Research Interests

• Mathematical modeling of water flow, solute and heat transfer in porous/fractured media
• Multiphase and multicomponent flow and transport in the vadose zone and groundwater system
• Numerical and analytical methods
• Estimating mass transfer parameters from laboratory or field measured water and solute distribution data
• Simulation of overland flow and stable isotope transport in runoff

• Develop a model for runoff flow and stable isotopes transport, using the diffusive wave approach with depression storage
• Develop a 1-D model for water flow and solute transport in swelling-cracking soils
• Inverse problem solution to identify parameters of the unsaturated soil
• Develop a 1-D model to simulate evaporation from bare soil
