Assessment And Optimization Of Environmental Systems Using Data Analysis And Simulation., Milad Ebrahimi
Assessment And Optimization Of Environmental Systems Using Data Analysis And Simulation., Milad Ebrahimi
Electronic Theses and Dissertations
For most environmental systems, specifically wastewater treatment plants and aquifers, a significant number of performance data variables are attained on a time series basis. Due to the interconnectedness of the variables, it is often difficult to assess over-arching trends and quantify temporal operational performance. The objective of this research study was to provide an effective means for comprehensive temporal evaluation of environmental systems. The proposed methodology used several multivariate data analyses and statistical techniques to present an assessment framework for the water quality monitoring programs as well as optimization of treatment plants and aquifer systems. The developed procedure considered the …
Performing A Steady-State Seepage Analysis Using Seep/W : A Primer For Engineering Students., Matthew R. Broaddus
Performing A Steady-State Seepage Analysis Using Seep/W : A Primer For Engineering Students., Matthew R. Broaddus
Electronic Theses and Dissertations
This thesis is comprised of five independent modules that were developed to provide a primer to understanding groundwater seepage. These modules serve as the template to conduct steady-state seepage analyses through embankments utilizing SEEP/W, a finite element seepage modeling program. Module 1 and 2 are more theoretical in nature to provide the background knowledge necessary to conduct a steady-state seepage analysis, while Modules 3, 4, and 5 focus more on the application of seepage models and how they can be used to solve various groundwater seepage problems. Supplementary material, including PowerPoint presentations, handouts, and a manual on how to utilize …
Three Dimensional Modeling Of Wekiva Springshed With Wash123d, Sandeep Paladagu
Three Dimensional Modeling Of Wekiva Springshed With Wash123d, Sandeep Paladagu
Electronic Theses and Dissertations
This thesis presents a three-dimensional groundwater modeling of Wekia springshed in central Florida using a numerical model, WASH123D. Springs have historically played an important role in Florida's history. The Wekiva River is a spring-fed system associated with about 19 springs connected to the Floridan aquifer. With increased urbanization and population growth in this region, there has been an increased strain on the water levels of Floridan aquifer which is a major source of potable water. Maintaining groundwater recharge to the aquifer is a key factor of the viability of the regional water supply as well as Wekiva ecosystem. Hence, the …
A New Paradigm Of Modeling Watershed Water Quality, Fan Zhang
A New Paradigm Of Modeling Watershed Water Quality, Fan Zhang
Electronic Theses and Dissertations
Accurate models to reliably predict sediment and chemical transport in watershed water systems enhance the ability of environmental scientists, engineers and decision makers to analyze the impact of contamination problems and to evaluate the efficacy of alternative remediation techniques and management strategies prior to incurring expense in the field. This dissertation presents the conceptual and mathematical development of a general numerical model simulating (1) sediment and reactive chemical transport in river/stream networks of watershed systems; (2) sediment and reactive chemical transport in overland shallow water of watershed systems; and (3) reactive chemical transport in three-dimensional subsurface systems. Through the decomposition …
