Fault Box Modeling Of Dip Slip Faults: A Framework For Fault Box Design And Future Studies, Hailey Pressnell Jan 2025

Fault Box Modeling Of Dip Slip Faults: A Framework For Fault Box Design And Future Studies, Hailey Pressnell

Master's Theses

The behavior of soils during surface fault rupture is a serious concern in the planning and design of infrastructure that may be located within or near a fault zone. Challenges associated with developing mitigation measures for surface fault rupture include the uncertainty of fault rupture and the variability of fault behavior. Current analytical procedures define surface fault rupture according to the type of fault movement (strike slip, normal or reverse), the amount of displacement on the fault, and the mechanics of the material overlying the fault. The purpose of this thesis is to reconfirm analytical solutions and gain a better …


Moon Rocker: Eva Sample Bag And Dispenser, Birk D. Smith, Albert J. Kasinski, Christian Clephan Jun 2022

Moon Rocker: Eva Sample Bag And Dispenser, Birk D. Smith, Albert J. Kasinski, Christian Clephan

Mechanical Engineering

NASA’s next mission to the moon (Artemis) requires a device to dispense bags for holding and collecting rock samples on the lunar surface. The device must be lightweight, easy to use with an astronaut suit, and capable of withstanding the moon’s harsh environment. Our team has designed and revised several prototype dispensers to accomplish this challenge. Through testing and observations made while building our structural prototype, changes were made to build a more durable and usable dispenser. This led to our verification prototype, which was constructed with a carbon fiber frame and aluminum, or 3D printed smaller components. After manufacturing …


Tholos - Eva Sample Location Calibration Device, James Verheyden, Kat Gipson, Julia Rios, Ben Trust Jun 2022

Tholos - Eva Sample Location Calibration Device, James Verheyden, Kat Gipson, Julia Rios, Ben Trust

Mechanical Engineering

To support NASA’s upcoming Artemis missions, an extravehicular activity (EVA) photometric calibration scale was developed to replace the Apollo-era Gnomon device. The Gnomon was a gimbaled stadia rod mounted on a tripod which provided color and reflectivity photo calibration, vertical orientation, and solar shadow direction, to include in photos of lunar geologic samples and features. With over 50 years of innovation since the first Gnomon deployment on Apollo 11, this redesign of the photometric calibration scale will support NASA’s missions in the modern day. The Tholos™, named after the ancient Greek repository of standardized measures, consists of a quadrupedal design …


Modeling The Groundwater Basin In The Northern Cities Management Area, Allyson Swain Jun 2021

Modeling The Groundwater Basin In The Northern Cities Management Area, Allyson Swain

Master's Theses

A model was developed to simulate the groundwater of 8,300 acres of the Northern Cities Management Area (NCMA), which encompasses the northern portion of the Arroyo Grande Watershed and a small subset of the Santa Maria Valley Groundwater Basin. This watershed and groundwater basin is located on the coast and contains Oceano and the Cities of Arroyo Grande, Grover Beach, Pismo Beach. Groundwater in the NCMA is used heavily for agricultural irrigation in the southern portion and municipal applications in the northern portion. Up to 18 of these municipal wells and over 50 irrigation wells are drawing groundwater at any …

Effects Of Using Clay Nanoparticles As A Soil Amendment To Remove Nitrate From Stormwater, Megan P. Abutin Jun 2018

Effects Of Using Clay Nanoparticles As A Soil Amendment To Remove Nitrate From Stormwater, Megan P. Abutin

Master's Theses

Development of urban areas continues to increase, disrupting the natural ecosystem and the pathways for water to drain into downstream water bodies. As the amount of impervious area increases, pollutants can accumulate on the surface and enter the water cycle by stormwater. In most cities, the stormwater flows into a storm drain that is discharged into a water body. Low Impact Development technology has been developed to treat stormwater prior to discharge downstream. A bioretention cell is used to treat stormwater pollutants such as nitrate, phosphorus, total suspended solids, and metals. Past research has indicated that the removal efficiency of …


A Study Of Marine Terrace Formation Along The California Central Coast, Mary C. Devlin Nov 2017

A Study Of Marine Terrace Formation Along The California Central Coast, Mary C. Devlin

Natural Resources Management and Environmental Sciences

Marine terrace formation is in many instances attributed to wave action, and shore platforms are often called “wave-cut”. However, alternative models for marine terrace formation suggest that other types of physical and chemical weathering have a more central role in the formation of marine terraces than is widely acknowledged. Roering and Retallack (2012) concluded that the roles of subaerial physical and chemical weathering are significant, and played a major role in the formation of the terraces. In this study, weathering of beach cliffs and shore platforms associated with marine terraces at eight sites in two different locations along the central …

Depth To Bedrock Estimations Using The H/V Spectral Ratio In The San Joaquin Valley, Tyler A. Morelli Aug 2013

Depth To Bedrock Estimations Using The H/V Spectral Ratio In The San Joaquin Valley, Tyler A. Morelli

Natural Resources Management and Environmental Sciences

Basin depth is a fundamental parameter in many types of geologic studies such as resource exploration and regional tectonic mapping. The Horizontal-to-Vertical Spectral Ratio (“H/V”) method has been successfully applied to estimating of basin depths up to several hundred meters. In this study the H/V method is applied to the deep basins on the western side of the San Joaquin Valley to determine the thickness of the sedimentary layers and depth to bedrock. Microtremor data from Earthscope Seismic Array stations are ideal to test the accuracy of the H/V method on deeper basins because the data is of high-quality and …
