Direct Solution to Problems of Open Channel Transitions

*Existing methods of solving problems of open channel transitions involve trials-and-error solution of higher degree equations and no direct solutions are available in technical literature....*

Three-Dimensional Open Channel Flow

*An open channel flow is usually three-dimensional consisting of the primary and secondary flows. The primary flow is defined herein as the flow component in the longitudinal direction...*

Forced Plumes in a Stratified Reservoir

*A comprehensive two or three-dimensional model for a forced plume is described in which there are no restrictions necessary in the choice of cross-sectional velocity or density profiles,...*

Effect of Channel Meanders on Flood Stage in Valley

*Results of this study indicate that for a meandering channel in a valley there is an interaction between the channel flow and valley flow. The nature of the interaction varies with stage,...*

Experiments on Surface Buoyant Jet

*An experimental investigation of a surface buoyant jet is presented. The densimetric Froude number and the Reynolds number of the discharge channel were 3.6 and 33,000, respectively. Longitudinal...*

Inelastic Section Response by Tangent Stiffness

Cross-Sectional Imperfections and Column Stability

*A method to determine the elastic buckling strength of imperfect closed polygon columns has been developed. A set of eight equilibrium equations was developed but was reduced to a set...*
