Determination and Prediction of Products of Trace Metal Removal in Laboratory and Field Scale Vertical Flow Bioreactors
(2016-05)
Mine drainage is characterized by elevated concentrations of dissolved iron, sulfate, and trace metals and generally exhibits an acidic pH. These constituents, particularly trace metals, can pose serious risks to both ...
Development and evaluation of a hydrological and hydraulic coupled flood prediction system enabled by remote sensing, numerical weather prediction, and deep learning technologies
(2021-05-14)
Floods triggered by extreme precipitation are the most frequently occurring and disastrous natural hazards in the world. However, it is still challenging to provide accurate and flood mapping, flood damage estimation, and ...
The Impact of a Private Water Enterprise on Household Water Services in Rural Ghana
(2020-05-08)
The goal of this dissertation is to investigate the effectiveness and sustainability of a private water service delivery model in a rural, developing context. Recent studies have found evidence for greatly increased ...
Effectiveness of impermeable barriers for retardation of pollutant migration /
(1983)
This paper presents the results of the analysis of the movement of contaminated ground water under or through an imperfect barrier. The first phase of the analysis consists of the development of an analytical solution for ...
Assessing Impacts of Precipitation and Parameter Uncertainty on Distributed Hydrologic Modeling
(2013)
Distributed hydrologic models, based on conservation laws, simulate the flow of water over and through the land surface in response to forcing from precipitation, transpiration, and evaporation. Conservation laws provide ...
Design of a general methodology for the evaluation and categorization of an environmental program with special reference to Costa Rica.
(1982)
This research essentially consists of two parts. In the first part, methodological studies were prepared as the basis for the development of the general methodology by which each government or institution can adapt and ...
Air quality cumulative effects assessment for United States Air Force bases.
(1998)
An air quality CE significance rating procedure was developed through adaptation of existing EIA significance evaluation methods combined with expert opinion and professional judgment. The procedure includes 18 factors for ...
Designing and Characterizing Surfactant Formulations for Detergency of Oily and Solid Non-Particulate Soils
(2020)
Laundry detergency is a complex process at the nexus of soil, surfactant, solid substrate, and wash condition. This dissertation contains the following two major topics. The first topic focused on developing surfactant ...
UNDERSTANDING ULTIMATE SHEAR BEHAVIOR OF PRESTRESSED CONCRETE GIRDER BRIDGES AS A SYSTEM THROUGH EXPERIMENTAL TESTING AND ANALYTICAL METHODS
(2017-07)
A prestressed concrete bridge is a complex system. The interconnectivity of several girders, a deck, and secondary elements such as diaphragms makes their behavior difficult to represent. Additionally, the shear behavior ...
