Combine Effects Of Heavy Storm, Sea Level Rise, And Wind-Induced Surge On Flooding In A Low-Gradient Coastal Watershed In Eastern Virginia, Rutvik Rajendrabhai Patel
Combine Effects Of Heavy Storm, Sea Level Rise, And Wind-Induced Surge On Flooding In A Low-Gradient Coastal Watershed In Eastern Virginia, Rutvik Rajendrabhai Patel
Civil & Environmental Engineering Theses & Dissertations
This dissertation examines and presents mechanisms of flooding in a low-gradient coastal watershed, located in Virginia Beach, Virginia, USA. The watershed comprises the North Landing River watershed and the West Neck Creek watershed, both characterized by a low topographic gradient. The analysis relied on examining simulations generated using one-dimensional and two-dimensional HEC-RAS models. These models were developed using a 1-m digital elevation model (DEM) obtained from the U.S. Geological Survey (USGS). To calibrate and validate the models, unsteady flows resulting from historical hurricanes (e.g., Matthew, Sandy, and Isabel), southern winds, and/or rising sea levels were utilized. Some flows were caused …
Demystifying Utility Coordination: Understanding The Basics, Josshe I. Palm
Demystifying Utility Coordination: Understanding The Basics, Josshe I. Palm
Purdue Road School
This session will explain utility coordination to non-utility coordinators. It will help educate others about the role and responsibilities of a utility coordinator, an OSA, easy UC and design mistakes to avoid, scope and design considerations, items commonly overlooked, when to coordinate SUE, and how to work with your UC to request a letting adjustment. We will also highlight UC submittals and allow time for questions about the UC’s role in a project’s success.
Containerization Of Seafarers In The International Shipping Industry: Contemporary Seamanship, Maritime Social Infrastructures, And Mobility Politics Of Global Logistics, Liang Wu
Dissertations, Theses, and Capstone Projects
This dissertation discusses the mobility politics of container shipping and argues that technological development, political-economic order, and social infrastructure co-produce one another. Containerization, the use of standardized containers to carry cargo across modes of transportation that is said to have revolutionized and globalized international trade since the late 1950s, has served to expand and extend the power of international coalitions of states and corporations to control the movements of commodities (shipments) and labor (seafarers). The advent and development of containerization was driven by a sociotechnical imaginary and international social contract of seamless shipping and cargo flows. In practice, this liberal, …
Statistical Analysis For Water Quality Data Using Anova (Case Study- Lake Burullus Influent Drains), Mohamed Hussein Hegazy
Statistical Analysis For Water Quality Data Using Anova (Case Study- Lake Burullus Influent Drains), Mohamed Hussein Hegazy
Civil Engineering
Lake Burullus is considered one of the most valuable northern lakes in Egypt due to its unique ecological system and special location. Over the past four decades, the lake has suffered from high contamination levels due to expansion in fish farming and increasing of agricultural drainage water entering the southern side of the lake through eight influent drains. This research aims to assess the current situation of the lake’s influent drains. For this purpose, two types of statistical analysis, Mean average method, and Analysis of Variance (ANOVA) were used. The water quality conditions for six major drains (Therah (Tira), Nashart, …
Development Of Erosion Functions For Micp-Treated Beach Sand, Saeed Booshi
Development Of Erosion Functions For Micp-Treated Beach Sand, Saeed Booshi
UNF Graduate Theses and Dissertations
This thesis investigates the effectiveness of microbially-induced calcium carbonate precipitation (MICP) using the recently introduced bioslurry treatment method via surface percolation. To simulate realistic water forcing conditions, a piston-style erosion rate testing apparatus, specifically the Florida Department of Transportation Sediment Erosion Rate Flume, was used. Initial tests conducted at a high shear stress of 42 Pa revealed that a combination of 15% bioslurry and 85% cementation solution exhibited the strongest erosion resistance when compared to other ratios between bioslurry and cementation solution. Subsequent experiments focused on separating the specimen into a "loose" part and a “surface crust,” with shear stresses …
