LSU Doctoral Dissertations
The objective of this dissertation was to investigate the fate and transport of microorganisms in coastal subsurface. Two topics were studied: (1) evaluation of the performance of the Marshland Upwelling System (MUS) in removing fecal bacteria and the background recovery after it is shut down; (2) Investigation of the effects of salinity and soluble organic matter (SOM) on sorption of MS-2 and development of a model to describe the sorption and transport process. The MUS showed effective performance in removing fecal bacteria during its 32 month operation period at Bayou Segnette Site. The removal efficiency was increased with its operation …

Physical Modeling Of Flow And Sediment Transport Using Distorted Scale Modeling, Ryan L. Waldron
LSU Master's Theses
As coastal Louisiana's land loss problem continues to grow unabated, many different solutions have been proposed. One such solution is the concept of diverting fresh water and sediment from the river into the coastal wetlands. Louisiana State University has a Small Scale Physical Model (SSPM) for the study of the potential of such diversions; it is deisgned to study the bulk movement of sediment in the river and diversions. The model is a distorted scale model with a horizontal scale of 1:12,000 and a vertical scale of 1:500; this extreme distortion has brought into question the applicability of the model. …
