Evaluating Hazus-Mh Flood Model Consequence Assessments Of Urban And Rural Coastal Landscapes Using Adcirc Generated Flood Data From Hurricanes Isaac And Laura, Katherine Faye Jones
Evaluating Hazus-Mh Flood Model Consequence Assessments Of Urban And Rural Coastal Landscapes Using Adcirc Generated Flood Data From Hurricanes Isaac And Laura, Katherine Faye Jones
LSU Master's Theses
Emergency managers rely on a variety on models and outputs, such as Hazards United States Multi- Hazard (Hazus-MH) and the Coastal Emergency Risk Assessment (CERA) visualization tool, to make decisions in the days leading up to and following hurricane events. This study focuses on using Hurricane Isaac (2012) and Hurricane Laura (2020).ASGS-CERA geoTIFFs, created from generated ADCIRC Prediction System data, in the Hazus-MH Flood Model to test using these two tools together in urban and rural areas. These ASGS-CERA integrated Hazus-MH studies were compared with Hazus-MH studies using the standard Hazus-MH surge methodology. They were tested for accuracy in both …
Quantifying Discharge On The Lower Mississippi River Physical Model, Taylor S. Cagle
Quantifying Discharge On The Lower Mississippi River Physical Model, Taylor S. Cagle
LSU Master's Theses
The Lower Mississippi River Physical Model (LMRPM) is a distorted, movable-bed physical model that replicates the hydraulics and bedload (sand) transport of the lower 195 miles of the Mississippi River. One year of flow and sediment transport on the prototype can be modeled in approximately one hour. With the ability to simulate long periods of time on the Lower Mississippi River in such a short time frame, the model can provide unique insight into subjects such as the potential effects from relative sea level rise on the lower river’s hydraulics and sediment transport. Quantifying discharge on the LMRPM is an …
Effects Of Historical Land-Use Change On Surface Runoff And Flooding In The Amite River Basin, Louisiana, Usa Using Coupled 1d/2d Hec-Ras–Hec-Hms Hydrological Modeling, Alexandre G. H. Cowles
Effects Of Historical Land-Use Change On Surface Runoff And Flooding In The Amite River Basin, Louisiana, Usa Using Coupled 1d/2d Hec-Ras–Hec-Hms Hydrological Modeling, Alexandre G. H. Cowles
LSU Master's Theses
The Amite River Basin is a largely rural watershed spanning parts of four counties in southern Mississippi and seven parishes in southeast Louisiana, with basinwide imperviousness increasing from 0.82% in 1938 to 3.85% in 2016. The Basin has been the subject of significant research interest since catastrophic flooding in 2016 caused 13 deaths and widespread damages. Rapid development in recent decades has led to an expansion of impervious surfaces in Baton Rouge and surrounding areas, encroaching on floodplains and wetlands. At the basin scale, differences in flooding due to impervious cover changes were found to be somewhat limited, particularly along …
Stream Power Analysis Of The Mid-Barataria Conveyance Channel Model, Jack Graham
Stream Power Analysis Of The Mid-Barataria Conveyance Channel Model, Jack Graham
LSU Master's Theses
Louisiana’s coast is disappearing at an alarming rate. Erosion, subsidence, sea level rise, and the devastating impacts from hurricanes have contributed to the loss of thousands of square miles of land that was once a thriving ecosystem. The Louisiana government is taking action to help protect and restore these coastal habitats, which are a home to some two million people and numerous species of animals, birds, and fish. The Mid-Barataria Sediment Diversion is a new type of project to help create land in Barataria Basin. Conceptually, the diversion is designed to use the available sediment and stream power provided by …

Operation Procedures Of Mid-Barataria Sediment Diversion Model To Reproduce Hydraulics And Sediment Transport, Chase Holston
LSU Master's Theses
The Lower Mississippi River Physical Model (LMRPM) is a distorted, movable bed model that simulates the hydraulics and sediment transport in the lower 195 miles of the Mississippi River. Carved into the model are both existing hydraulic structures, such as the Bonnet Carré Spillway, and proposed structures, such as the Mid-Barataria Sediment Diversion (MBSD). The MBSD will be the first sediment diversion built as part of Louisiana’s Coastal Master Plan, so incorporating the diversion in the LMRPM will be a useful tool to understanding how the diversion can impact the river hydraulics and bedload transport. The objective of this thesis …
