Research Work

• Ph.D. Dissertation: “Quantifying seasonal variations in continental surface water storage using a catchment-based hydrology and routing model with explicit surface water bodies”-  We present a macro-scale hydrologic modeling system with an explicit representation of storage and movement of water in river channels and floodplains. The overall modeling system, called the Catchment-based Hydrologic And Routing Modeling System (CHARMS), is comprised of a  land surface model and a river routing model that operate on a network of hydrologic catchments (or watersheds). The land surface model in CHARMS is based on the National Center for Atmospheric Research (NCAR) Community Land Model (CLM). The river routing model in CHARMS generates river discharge by transporting runoff generated by the catchment-based CLM through the river network. The routing model uses information on channel cross-section geometry, derived from the 90 m SRTM DEM, to simulate river discharge and the associated flow depth and inundation width. CHARMS was implemented over the Wabash River basin in the Central United States (drainage area 72282 km2), and simulated streamflow was validated using daily observations. Simulated flow depth and inundation extent generally followed seasonal variations in observed flooding and droughts. Limitations of some of the assumptions and scaling factors used in this study and the issues that need to be addressed for a continental or global scale implementation of CHARMS are discussed. This paper serves as the foundation for a catchment-based, global land surface modeling framework that could incorporate spatio-temporal variations in surface water bodies, as well as satellite measurements of these variations.
  

• M.S.C.E. Thesis: “Effects of streamflow regulation and land cover change on the hydrology of the Mekong River basin”- The Variable Infiltration Capacity (VIC) hydrologic model was used to simulate rainfall-runoff processes as they are affected by land cover in the Mekong River Basin. The VIC model was implemented at a ¼ degree resolution, for the period January 1979 through December 2000, and was calibrated so that observed streamflow was reproduced to a reasonable extent at selected discharge measurement stations on the main-stem of the Mekong and its tributaries. Model calibration included scaling the precipitation data in parts of the Lower Mekong Basin where scarce meteorological station densities otherwise lead to significant underprediction of observed flows. A water management model (MWMM) was developed to simulate the effects of streamflow regulation by existing and planned major dams and reservoirs in the basin. The MWMM, which is driven by VIC simulated streamflow and assumed operating procedures, produces simulations of annual hydropower that are in approximate accord with observed (or designed) values for most of the dams. The overall effects of the dams in the MWMM on the monthly streamflow of the main-stem Mekong were found to be quite small (less than 3.5% of observed monthly streamflow). The VIC model and the MWMM were then used to evaluate the hydrologic effects of changes in monthly streamflow resulting from changes in land cover in different parts of the basin. The maximum predicted streamflow change for current relative to historic land cover conditions was an increase of 53 percent in mean annual streamflow for the Chi-Mun River, a tributary to the Lower Mekong Basin in which major conversions of forest to cropland have occurred over the last 50 years.
