Abstract: Sediment‐driven density currents exist in most secondary sedimentation basins and cause the usual hydrodynamic flow pattern in these basins to deviate substantially from uniformity. The mathematical model introduced here ...

Abstract: A mathematical model of sediment laden, density affected turbulent flows is presented. The finite element technique is used in conjunction with the Newton iterative method to solve the resulting partial differential ...

Abstract: A key parameter in modeling soil-venting systems is relative air permeability, determined as a function of liquid saturation. The focus of the present study was to characterize the relationship of the relative air permeability ...

Abstract: Geographic information systems (GIS) provide a digital representation of watershed characteristics used in hydrologic modeling. This paper summarizes past efforts and current trends in using digital terrain models and GIS ...

Abstract: This study develops a site-specific analysis of sediment transport for the in-the-wet construction of Olmsted Locks and Dam on the Ohio River using the HEC-RAS model. Results from the analysis are used to assess the frequency ...
