Verification of a Generalized Mudflow Model
This paper presents the results from recently completed studies verifying the accuracy and applicability of a generalized one-dimensional model for dynamic routing of mudflows. Numerical...
An Efficient, Accurate Technique for Navier-Stokes Solution
Solution of the Navier-Stokes equations for a Newtonian, incompressible fluid (such as water) requires both accuracy in the assuring conservation of mass and efficiency of convergence....
Calibration of an Evapotranspiration Model Using Eddy Correlation Methods
An evapotranspiration (ET) prediction model was developed by calibrating the H. L. Penman equation for an alfalfa reference crop in the southwestern Oklahoma region. Evaporative flux for...
Wind Tunnel Investigation of a Twin Deck Suspension Bridge
Wind tunnel measurements of the response of a twin deck suspension bridge to dynamic wind loads are presented. The investigation was concerned with the determination of the deck response...
Sunshine Skyway Ship Collision Criteria
The 'new' crossing of Sunshine Skyway was born, not only to replace the previous crossings and improve the regional economy but also with increased clearances...
