A Conceptual Framework For Phase-Dependent, Composite Flood Risk Index (Fri) Curves Based On The Relationship Between Temporal Probability Of Flood Occurring (Ph) And Flood Vulnerability Index (Fvi) Along With Maps Of Fvi Within The Amite River Basin Based On The August 2016 Flood., Austin S. Guerin Mr.
LSU Master's Theses
Efforts directed at determining community vulnerability to flooding are limited and only include economic (dollar damages) and public safety impacts and do not consider the phase dependency of the system, i.e., pre-, during- and post-storm, both critical shortcomings for more broadly assessing community risk and developing comprehensive plans and mitigation strategies. This thesis first develops a framework based on a Flood-Vulnerability Index (FVI) approach and then demonstrates its usefulness, at the census tract level of detail, for three parishes in the Greater Baton Rouge, LA area, based on the August 2016 flood. FVI’s indicators are multidimensional and phase dependent: “Pre-Flood” …
Historical Changes In Planform Geometry Of The Amite And Comite Rivers And Implications On Flood Routing, Kathleen E. Harris
Historical Changes In Planform Geometry Of The Amite And Comite Rivers And Implications On Flood Routing, Kathleen E. Harris
LSU Master's Theses
The Amite River Basin is a 2,220 square-mile basin spanning from southwest Mississippi through southeast Louisiana, encompassing Baton Rouge and its suburbs. In response to historic flooding in August 2016 and other major flood events in the past several decades, the basin has been the subject of a number of studies to quantify the impacts of changes in land-use and reduction in river length and sinuosity. However, there have yet to be relationships defined between the changes in the historical river planform and the resulting flow, stages, and subsequent flood depths. River lengths and sinuosity were measured from the 1930s …
Composite 1-Dimensional Modeling Of The Expanded Small Scale Mississippi River Model, Benjamin Joseph Hartman
Composite 1-Dimensional Modeling Of The Expanded Small Scale Mississippi River Model, Benjamin Joseph Hartman
LSU Master's Theses
Stream wise 1-dimensional numerical modelling couples well with long term, large domain physical modelling because of its ability to perform simulations quickly. The downsides are limitations in replicating some complex hydrodynamics and sediment transport behavior. In this study, a 1-dimensional model of a section of the Expanded Small Scale Physical Model (ESSPM) is developed using the USACE HEC-RAS software with a goal of investigating the ability of a 1-dimensional model to accurately replicate hydraulics at ESSPM time scales. Additional simulations are conducted to examine the impact of varying distortion scales, non-frictional energy losses and synthetic sediment on hydraulic behavior. The …
