Evaluation Of Water Resources And Hydraulic Influences In The Restoration Of The Western Part Of The Mesopotamian Marshlands, Ali Kareem Al-Quraishi

Graduate Theses and Dissertations

The purpose of this study is to assess the water resources and water conveyance system of the western part of the Mesopotamian marshes (Al-Hammar marsh) as well as develop a water conveyance system to distribute water throughout the western Al-Hammar marsh. These processes are significant to identify the current restoration problems and help to create restoration strategies for the marsh. Also, proper management strategy to the Al-Hammar marsh is necessary to preserve the marsh ecosystem, irrigate lands, and provide domestic necessities in the villages.

The overall project is divided into three main chapters which address the current ecological and hydrological …

A Numerical Investigation Of The Implications Of Altered Channel-Floodplain Connectivity On Hydrodynamic Flood Wave Processes, Colin F. Byrne

Civil Engineering ETDs

With severely altered rivers throughout the developed world, hydrodynamic processes and floodplain connectivity have changed drastically. The research presented here focuses on quantification of two hydrodynamic processes: flood wave attenuation and channel-floodplain fluxes. Objectives of the three research chapters were to (1) evaluate how the ecosystem service of flood wave attenuation has changed with the implementation of river engineering practices as well as contemporary river restoration efforts, (2) describe the sensitivities of flood wave attenuation to contemporary and altered conditions, and (3) characterize channel-floodplain connectivity through lateral flux metrics. All chapter objectives were met using high-resolution, two-dimensional hydrodynamic modeling techniques …

Spatial And Temporal Study Of Heat Transport Of Hydrothermal Features In Norris Geyser Basin, Yellowstone National Park, Ruba A. M. Mohamed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monitoring thermal activity in Yellowstone National Park is required by the United States Congress to maintain the safety of the visitors and park service personnel and to protect the integrity of the park. This dissertation is part of a study initiated in the early 2000s to monitor the thermal activity in the park with focus on Norris Geyser Basin, the hottest geyser basin in the park. The study is considered the first multiple-year study in the basin which took place between August 2008 and October 2013. In this study, at least one thermal infrared image was acquired every year using …

Wave Energy Assessment In Southern Central Java Island And Control Method For Maximizing The Captured Power In Wave Energy Converters, Fatima Sultan Ghdayer Ali Alaryani

Theses

This thesis discusses the wave energy potential of the Indian Ocean on the south coast of Central Java Island, where no previous known similar study has been conducted. A control technique that involves a dynamic electrical model was established. The following objectives were achieved. The first was to determine the ideal location to implement wave energy conversion (WEC), and the second objective was to simulate the significant wave height by using the novel control method.

To achieve these goals, the following steps and procedures were implemented. Wave energy assessment was conducted for the Indian Ocean on the south coast of …
