Detailed bathymetry data are collected on short reaches and are usually not available for the entire stream network at a regional scale. By using the field data collected for a reach along the Brazos River in Texas, a geographic information system (GIS) framework for describing river channel bathymetry at regional-scale is presented. The framework is based on deriving relationships among differ...

An efficient and high-fidelity design approach is proposed by combining global and local optimization methods for wing planform and surface design. For enhanced design results, aerodynamic shape optimization process is carried out via 2-stage with different optimization strategy. In the first stage, global optimization techniques are applied to planform design with a few geometric design variab...

Direct numerical simulation is used to investigate the transition induced by threedimensional isolated roughness elements in a supersonic boundary layer at a free stream Mach number of 3.5. Simulations are performed for two different configurations: one is a square planform roughness and the other is a diamond planform roughness. The mean-flow calculations show that the roughness induces counte...
