Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

Creator:: Jensen, Robert E.
Abstract:: Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...

A Multivariate Comparison of Drone-Based Structure from Motion and Drone-Based Lidar for Dense Topographic Mapping Applications

Creator:: Simpson, Chase H.
Abstract:: Unmanned aircraft systems (UAS), also known as drones, are an increasingly popular method of collecting surveying and mapping data. Two common drone-based mapping techniques are lidar and structure from motion (SfM) photogrammetry, and a frequently-heard (yet nearly impossible to answer) question is: “which is better?” The most common metric for...

An Efficient Workflow and Accuracy Assessment for ICESat-2 and Multispectral Imagery Fusion for Bathymetric Mapping

Creator:: Babbel, Benjamin J.
Abstract:: Interest in mapping bathymetry from multispectral satellite imagery has grown steadily since the 1970s. Notwithstanding the significant advancements made during this time, one limitation is that the group of algorithms collectively referred to as Satellite Derived Bathymetry (SDB) generally require “seed depths,” hindering their use for areas lacking reliable reference...

Fate of THMs in Columbia River basalts during aquifer storage and recovery

Creator:: Bertrand, Danelle
Abstract:: Use of basalt aquifers for aquifer storage and recovery (ASR) systems is increasing in the Pacific Northwest due to the large aerial extent of the Columbia River Basalt Group and the suitability of basalts as ASR reservoirs. However, the degradation of trihalomethanes (THMs), potentially carcinogenic disinfection by-products present in the...

Observations of cross-shore sediment transport and formulation of the undertow

Creator:: Guannel, Gregory E.
Abstract:: A new set of data from a large-scale sand bar migration experiment is presented. During this experiment, two sandbars were generated. One of the bar was generated by the action of undertow, and sediment moved offshore. The other bar was generated by the shoreward movement of sediment coming from the...

The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

Creator:: Streebin, Leale E.
Abstract:: The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

The effect of organic sorbent concentration on sorption kinetics

Creator:: Dolan, Mark E.
Abstract:: Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations in the liquid were sampled with time and analyzed by electron capture detector gas chromatography. Sorption was found to be a two stage process characterized by a rapid initial uptake followed by a extended...

Of Planes and Plumblines: Map Projections and Differential Leveling in a GNSS-based 3D Geodetic Framework

Creator:: Dennis, Michael L.
Abstract:: Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...

Evaluation of desktop learning modules in civil engineering classrooms to promote inductive and interactive learning

Creator:: Buker, Kamilah E.
Abstract:: Students in undergraduate engineering programs typically do not synthesize content learned from disparate course work until the end of their final terms of college. As an example, in undergraduate civil engineering programs, transportation engineering concepts (e.g., geometric alignment, asphalt design procedures) and geotechnical engineering concepts (e.g., shear strength of soils,...
