  • Consolidation characteristics of sand-clay mixtures

    Creator:
    Anderson, Donald G. (Donald Gordon)
    Abstract:
    Combinations of cohesive and cohesionless soils are often encountered when evaluating the engineering properties of soils. The stress-volume characteristics of the mixed soil are found to vary according to the proportion of each component. If the cohesive soil composes more than a certain fraction of the material, the magnitude of...

  • Disposal of sandy pipeline dredge spoils by end dumping

    Creator:
    Pyles, Marvin Russell
    Abstract:
    Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

  • Behavioral thresholds in mixtures of sand and clay

    Creator:
    Simpson, Daniel Corder
    Abstract:
    Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

  • Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

    Creator:
    Converse, Jordan D.
    Abstract:
    With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...

  • Nitrate and pesticide transport under pear production in clay and sandy soil

    Creator:
    Cao, Weidong
    Abstract:
    Groundwater contamination on irrigated land is of concern in this nation and around the world. In order to reduce the potential of groundwater contamination by agricultural practices such as irrigation, fertilizer and pesticide application, vadose-zone monitoring and sampling are needed. The main objective of this study was to evaluate impacts...

  • New Simulation and Fusion Techniques for Assessing and Enhancing UAS Topographic and Bathymetric Point cloud Accuracy

    Creator:
    Slocum, Richard K.
    Abstract:
    Imagery acquired from unmanned aircraft systems (UAS) and processed with structure from motion (SfM) – multi-view stereo (MVS) algorithms provides transformative new capabilities for surveying and mapping. Together, these new tools are leading to a democratization of airborne surveying and mapping by enabling similar capabilities (including similar or better accuracies,...

  • Munition Mobility in Mixed Grain (Sand and Cobble) Environments

    Creator:
    Paskoski, Jessica
    Abstract:
    Nearly 24% of Formerly Used Defense Sites (FUDS) containing military munitions are in the nearshore coastal zone with approximately 30% of those sites containing heterogeneous sediment compositions of gravel-sand. Previous exploration in munition mobility was performed on beaches of sandy or muddy bottoms leaving the influence of heterogeneous sediment properties...

  • Beach Dune Subsurface Hydrodynamics and the Formation of Dune Scarps

    Creator:
    Bond, Hailey G.
    Abstract:
    The formation of beach scarps is a challenging morphodynamic phenomenon that the coastal community has yet to capture in coastal change models. Understanding scarp formation is crucial to accurately predicting coastal erosion and vulnerability during extreme events, as models without parameters for scarp formation and development severely underpredict total erosion...

  • Cyclic triaxial testing of low- to moderate-plasticity silts

    Creator:
    Butler-Brown, Jason J.
    Abstract:
    This project report presents a laboratory investigation of the dynamic behavior of saturated alluvial silty soils from sites in Oregon and Washington. The focus of the study was to document the liquefaction susceptibility, post cyclic strength, and volumetric strain behavior of the silt soils based on cyclic, undrained triaxial compression...

  • 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...
