Measuring and Correcting the Electrical Resistivity of Concrete Pore Solution in Fresh Mixtures

Creator:: Biever, Joseph H.
Abstract:: A vital aspect of concrete construction is quality assurance and control (QA/QC). Engineered structures must meet pre-determined and agreed-upon strength and durability requirements. Concrete falls into a specific category of infrastructure material because in most cases, these strength and durability requirements cannot be found until the material has at least...

Are watershed management plans selected and preferred by stakeholders considering current climate conditions robust against climate change scenarios? A sensitivity study of stakeholders spatially-explicit preferences

Creator:: Cannady-Shultz, Kenneth R.
Abstract:: In the light of the changing climate, the importance of designing effective watershed management plans that are likely to be implemented is becoming ever more important. This research introduces a new concept, consensus, for incorporation into stakeholder-guided interactive optimization of watershed management plans. User preferences were mathematically simulated based upon...

An Experimental Study on Violent Geysers in Vertical Shafts

Creator:: Elayeb, Ibrahem S.
Abstract:: A Geyser in a stormwater (SW) and combined sewer system (CSS) is an oscillatory and violent release of a mixture of air and water through vertical shafts. Violent geysers are highly destructive. In the case of combined sewer systems, many municipalities operate their systems at a fraction of their maximum...

Interactive Genetic Algorithms for watershed planning : an investigation of usability and human-centered design

Creator:: Piemonti, Adriana Debora
Abstract:: Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...

Evaluation of Low-Impact Development (LID) Treatment Train at OSU-Benton County Green Infrastructure Facility

Creator:: Saduova, Alisha
Abstract:: Urban stormwater runoff with a high impervious area can significantly impact pollution concentrations of receiving water bodies. The use of low impact development (LID), which mimics the hydrological properties of the site before development, has been studied in an increasing number of studies, and the available database has shown to...

On Undular Bores and Solitary Waves in Variable Depth

Creator:: Knowles, Jeffrey N.
Abstract:: Numerical results are presented using a higher-order pseudo-spectral method in order to solve the Zakharov-Craig-Sulem formulation of the Euler model. We study the effects of variable bathymetry on weakly-dispersive, weakly-nonlinear, shallow water waves. Improved predictions on wave amplitude and shoaling behavior are developed by analytical means in the context of...

Assimilation of Multi-Sensor Data into Numerical Hydrodynamic Models of Inland Water Bodies

Creator:: Javaheri, Amir
Abstract:: Numerical models are effective tools for simulating complex physical processes such as hydrodynamic and water quality processes in aquatic systems. The accuracy of the model is dependent on multiple model parameters and variables that need to be calibrated and regularly updated to reproduce changing aquatic conditions accurately. Multi-sensor water temperature...

Wave-by-wave Forecasting of Sea Surface Elevation for WEC Applications Utilizing NARX Neural Networks

Creator:: Gillespie, Alice
Abstract:: Forecasting of ocean waves over a short duration on the order of tens of seconds was approached with the optimization of wave energy conversion in mind. This study outlines the development of an artificial neural network model, specifically the Nonlinear Autoregressive Network with Exogenous Input (NARX), to predict a wave-by-wave...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Experimental Investigation of the Effects of Embedded Rebar, Cracks, Chloride Ingress and Corrosion on Electrical Resistivity Measurements of Reinforced Concrete

Creator:: Morales, Monica
Abstract:: The effects of steel reinforcement, chloride-induced corrosion initiation, cracking and delamination on the electrical resistivity measurements using the Wenner probe technique were studied experimentally on custom-designed reinforced concrete slabs. Investigation parameters included (1) probe configurations with respect to rebar mesh, (2) rebar density, (3) epoxy coating on the rebar, (4)...
