Resiliency Of Levee-Protected Power Networks To Flooding In A Changing Climate Integrating Environmental Justice, Seyed Saeed Miraee-Ashtiani

Theses and Dissertations

Electric power system (EPS) is an integral part of infrastructure systems. Ensuring its resiliency to extreme weather events and natural hazards is crucial to protect the safety, economy and public health. Recorded and projected data show an increase in the frequency and severity of extreme weather events and natural hazards attributed to a changing climate. It is critical to ensure the integrity of the aging infrastructure systems and to promote environmental justice by shrinking the energy-equity gap to lower power outages in disadvantaged communities.

An important aspect is the resiliency interdependency of EPS to other critical infrastructure systems, an aspect …

Practical Issues In Floodplain Mapping Over Large Regions, James Eric Braden

Electronic Thesis and Dissertation Repository

Flooding events are among the costliest and most frequent natural hazards occurring in Canada. Floodplain mapping is a non-structural flood management strategy that involves the formulation of hydrologic and hydraulic models to produce maps which predict extent and depth of floods. Practices and availability of floodplain mapping vary across Canada. The current state of floodplain mapping across Canada has been identified and reviewed. Vast areas of flood prone regions across Canada have been identified as not having floodplain maps or lacking updated ones. Large region floodplain maps have been recently introduced and can cover national and global regions. Limitations of …

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 …

Modeling Distributed Source Control Infrastructure At Neighborhood Scale For Mitigating Flood Risk In Amite River Watershed, Ahmad Amin Shefai

LSU Master's Theses

Flooding has always been a major threat to mankind. This is particularly true in urban areas due to urbanization-induced increasing impervious areas and subsequent increasing urban surface runoff, causing an increasing flooding risk to urban areas in spite of the fact that extensive flood control infrastructure has been constructed. The overall goal of this thesis is to present a distributed source control infrastructure-based approach for mitigating the flood risk. The new flood mitigation approach is demonstrated through the model implementation of a series of distributed source control infrastructure systems in the city of Denham Springs at a neighborhood scale. The …

Floodplain Analysis, Kyle Michael, Bryce Vollrath, Aaron Steele

Scholar Week 2016 - present

The village of Watseka, Illinois has experienced several 100-year floods over a short period of time and needs a solution to solve its flooding problem. The goal of the project is to come up with multiple solutions that could reduce flooding. All designs were intended to ensure that the wastewater treatment plant stays operational during flood conditions. To do so, analysis of the wastewater treatment plant was completed. Then, designs that focused on reducing river flood stages were analyzed. By preventing the river from reaching and cresting at it’s flood stage, the town’s risk of flooding is greatly reduced.

Calculation Of The Placement Of Vertical Drainage Wells Near An Open Water Source In The Conditions Of Waterlogging Of Built-Up Areas, B.K. Saliev

Irrigation and Melioration

The article discusses the methodology for calculating the intercepting drainage well that reveals the upper layer of the multilayer horizon, and presents analytical dependencies based on the hydrodynamic theory and formulas for approximate calculation of the location of the axial line of the blocking drainage between the source of flooding and the protected built-up area from flooding. In particular, mathematical methods have been improved to solve the forecast problems of flooding in conditions of different pressure, based on the relationship between the depressions and the incoming flow of pressure water into the drainage well. The presence of underground pressure water …

The ability to predict and plan for the impacts of superstorms on transportation infrastructure is key to mitigate future damages and losses. This study analyzed 51 combinations of future projections for representative concentration pathways (RCP) 4.5 and 8.5 scenarios, which were used …

Modeling Nature-Based Solutions For Climate Resilience, Mason Saleeba

Environmental & Water Resources Engineering Masters Projects

Riparian wetlands can serve as nature-based infrastructure that slow the rapid movement of water during high flow events. As the recurrence of high flow events increases due to global climate change, an improved understanding of the potential of wetland landscapes to provide flood mitigation is needed. This research addresses both the impacts of climate change and land cover on extreme flow events in the Otter Creek watershed in Vermont. The upstream portion of the basin is modeled with the Soil and Water Assessment Tool (SWAT) to investigate the impacts of climate change on extreme flow events. A Hydrologic Engineering Center's …

Flood Inundation Mapping For Huron Creek, Houghton County, Michigan, Sarah Washko

Dissertations, Master's Theses and Master's Reports

The 2018 Father’s Day Flood rattled the Houghton County, MI community. Thousands of dollars in damage to public and private property were incurred due to slope failure, scour and stagnant water. Though the flood was billed as a once-in-a-lifetime event, hazard mitigation planning has become essential, as extreme weather events are expected to become more frequent with a changing climate. While Federal Emergency Management Agency funding will provide detailed flood hazard maps in the future, mapping is expected to be several years out. To aid the City of Houghton community with immediate flood hazard mitigation planning, a hydraulic-based flood depth …

This study used in-depth interviews of permanent residents on Grand Isle, Louisiana, a remote barrier island, to better understand their perceptions of structural flood measures, non-structural responses to flooding and hurricanes, and perceptions of vulnerability to flooding, hurricanes, and climate change on a remote barrier island-Grand Isle, Louisiana. Residents' perceptions regarding the various structural measures implemented by the federal, state, and local government appeared mixed. Non-structural responses to flooding risks implemented at the household, community, state, and federal level continue to strengthen resiliency on Grand Isle. According to interviewees, aspects of environmental, rural, and economic vulnerability on Grand Isle impact …

Prediction Of Flood Hydrograph In Small River Catchments Using System Modelling Approach, Ahmed Nasr, Zeinab Bedri, Loreta Ramanauske

Conference papers

Floods remain to be one of the natural catastrophic disasters with serious adverse social and economic implications on individuals and communities all around the world. In Ireland, frequency of flood events have increased dramatically during the last forty years and is expected to continue to rise primarily due to changes in rainfall and temperature patterns as a result of the global climate change. Small river catchments are usually vulnerable to different types of flooding particularly those associated with “monster” rainfall events, which are characterised by short durations and high intensities. Therefore accurate prediction of flood hydrographs resulting from these rainfall …

Surface Water Flooding, Groundwater Contamination, And Enteric Disease In Developed Countries: A Scoping Review Of Connections And Consequences, L. Andrade, J. O'Dwyer, E. O'Neill, Paul Hynds

Articles

Significant volumes of research over the past four decades has sought to elucidate the social, infrastructural, economic, and human health effects of climate change induced surface flooding. To date, epidemiological and public health studies of flooding events have focused on mental health effects, vector-borne diseases, and infectious enteric disease due to floodwater contact (i.e. typically low consumption rates). The inherent nature of groundwater (i.e. out of sight, out of mind) and the widely held belief that aquifers represent a pristine source of drinking water due to natural attenuation may represent the “perfect storm” causing direct consumption of relatively large volumes …

Weighting The Perceived Importance Of Minimising Economic, Social And Environmental/Cultural Risks In Flood Risk Management, Zeinab Bedri, John O'Sullivan, Mark Adamson

Conference papers

In 2006, the Office of Public Works (OPW) began the National Catchment-based Flood Risk Assessment and Management (CFRAM) Programme through a series of pilot studies. A Multi-Criteria Analysis (MCA) Framework was developed through the CFRAM pilot studies that integrated a range of objectives related to human health and society, the environment and cultural heritage and the economy into the core process of selecting suitable flood risk management measures for a given area or location, and then for prioritising national investments for different schemes and projects. In support of this MCA framework, UCD, was commissioned to undertake a collaborative study with …

Restoring Floodplains In The Connecticut River Basin: A Flood Management Strategy, Abigail Ericson

Environmental & Water Resources Engineering Masters Projects

This research investigates how changes to floodplains in the Connecticut River Basin impact flood events. Climate impacted flows and increased development within the floodplain could lead to worsening flood events and less habitat availability for threatened species. Potential future conditions are evaluated through a wide range of scenarios to assess the range of possible impacts using a HEC-RAS 2D model. Three different flood events, 1-yr, 10-yr, and 100-yr, are evaluated for each scenario. Five metrics, Discharge, Depth, Time of Arrival, Flooding Duration, and Number of Buildings Flooded, are tracked for each scenario. These metrics are compared to select the ideal …

Use Of Sacrificial Embankments To Minimize Bridge Damage From Scour During Extreme Flow Events, Matthew Willi Brand

Graduate College Dissertations and Theses

The leading cause of bridge failure has often been identified as bridge scour, which is generally defined as the erosion or removal of streambed and/or bank material around bridge foundations due to flowing water. These scour critical bridges are particularly vulnerable during extreme flood events, and pose a major risk to human life, transportation infrastructure, and economic sustainability. Climate change is increasing the intensity and persistence of large flow events throughout the world, further straining bridge infrastructure. Retrofitting the thousands of undersized and scour critical bridges to more rigorous standards is prohibitively expensive, and current countermeasures inadequately address the core …

Weighting The Perceived Importance Of Minimising Economic, Social, And Environmental/Cultural Risks In Flood Risk Management, Zeinab Bedri, John O'Sullivan

Reports

A new national flood policy adopted in Ireland in 2004 set out that a range of flood-related impacts should be taken into account in planning flood risk management strategies and projects, including impacts on people, properties, the environment and cultural heritage. This was reinforced by the 2007 EU 'Floods' Directive that is aimed at the reduction of adverse consequences of flooding for human health, the environment, cultural heritage and economic activity.

In 2006, the Office of Public Works (OPW) began the National Catchment-based Flood Risk Assessment and Management (CFRAM) Programme through a series of pilot studies. A Multi-Criteria Analysis (MCA) …

Morphological Response Of Sand Bed Streams To Unsteady Flow Events: An Experimental Study, Etta Haley Gunsolus

Electronic Thesis and Dissertation Repository

Changes in riverine discharge, such as those due to reservoir flushing, seasonal variation or extreme precipitation events, can alter sediment transport rates and morphology of the stream bed. Experimental research investigated the effect of unsteady flow event hydrographs on stream bed morphological response. Laboratory experiments were conducted in a 5.0 m-long sediment transport flume with a bed comprised of a medium sand. Experimental hydrographs were composed of antecedent (base-flow), unsteady event (flood) and post- flood (return to base-flow) stages. Three distinct series of experimental laboratory runs were conducted to systematically investigate the effect of three characteristics of unsteady flow event …
