3d Hydrodynamic Model Development And Verification, Hussein A. M. Al-Zubaidi
3d Hydrodynamic Model Development And Verification, Hussein A. M. Al-Zubaidi
Civil and Environmental Engineering Master's Project Reports
A three-dimensional numerical model was developed to simulate hydrodynamic, temperature, and water quality distributions in rivers and lakes. In an attempt to get rid of the extra approximation and complexity, no coordinate transformation has been done and z-coordinate system has been employed. The governing equations are the continuity equation, free surface equation, momentum equations, and conservation equations of temperature and water quality. The model employs the time splitting technique which allows splitting the directions in which we end with two-dimensional governing equations and eventually the solution ends with a tri-diagonal matrix, which is easily solved by Thomas algorithm. The first …
A Study On The Current State Of Contaminants Of Concern Research, With A Focus On Biosolids And Regulations, Maren Mariah Fulton
A Study On The Current State Of Contaminants Of Concern Research, With A Focus On Biosolids And Regulations, Maren Mariah Fulton
Civil and Environmental Engineering Master's Project Reports
Wastewater treatment plants are a major source of contaminants of emerging concern, as these facilities are the main receptors of these products via household, commercial, and industrial drains, and transport via stormwater runoff. Biosolids are composed of numerous constituents, with a number of environmentally persistent and potentially toxic contaminants of emerging concern identified as present in large concentrations. Research is needed to understand the transport and fate mechanisms of these compounds in biosolids. Additionally, this research is needed to determine a new priority framework to regulate CECs, both on the national level and regional levels. Wastewater treatment plant influent and …
Management Plan For Western Painted Turtle (Chrysemys Picta Belli) At Fairview Creek Headwaters, Ashley Smithers
Management Plan For Western Painted Turtle (Chrysemys Picta Belli) At Fairview Creek Headwaters, Ashley Smithers
Environmental Science and Management Professional Master's Project Reports
Western painted turtles (Chrysemys picta belli) are found occupying Fairview Creek Headwaters (FCH) in Gresham, Oregon. This urban stream contains a large wetland with an adjacent butte, all managed by the City of Gresham. This management plan addresses the preferred habitat and population of turtles at the site. A habitat delineation of the site revealed specific locations where habitat improvements could take place as well as areas of already beneficial habitat. Two site plans were prepared showing areas of the site that could be enhanced with nesting habitat as well as additional aquatic habitat and basking habitat. A habitat study …
Mangrove Enhancement As A Climate Change Adaptation Strategy In The Republic Of The Marshall Islands (Rmi): Potential Ecosystem Service Shifts Following Colonization, Andrew S. Harwood
Mangrove Enhancement As A Climate Change Adaptation Strategy In The Republic Of The Marshall Islands (Rmi): Potential Ecosystem Service Shifts Following Colonization, Andrew S. Harwood
Environmental Science and Management Professional Master's Project Reports
The ability of Small Island Developing States (SIDS) and Pacific Island communities to adapt to the increasing sea-levels, storm surge, saltwater intrusion, and other threats posed by global climate change is critical to the survival of many of these local communities as well as their cultures (LivingIslands.org). One of the world’s most striking examples of a nation at great risk is the Republic of the Marshall Islands (RMI) in the central Pacific Ocean. Due to a combination of factors, including the country’s extremely low elevation above sea-level (an average of 2 meters) and lack of adequate structures to provide safety …
