Using Groundwater Modeling To Assess Groundwater And Stream Connectivity In A River Restoration Application, John Joseph Lunzer Apr 2019

Using Groundwater Modeling To Assess Groundwater And Stream Connectivity In A River Restoration Application, John Joseph Lunzer

Graduate Theses & Non-Theses

Historic placer mining operations along the Middle Fork John Day River (MFJD) north of Galena, Oregon have left the MFJD channel straightened, incised and lacking in riverbed structure. This lack of riverbed structure makes this stretch of the MFJD poor habitat for trout and migrating salmon. In order to restore this stretch of the MFJD to better serve aquatic species, Inter-Fluve Inc. (IF), United States Forest Service (USFS) and The Freshwater Trust (TFT) will be performing restoration to both the MFJD channel as well as Bear Creek, a tributary of the MFJD. The proposed restoration work will consist of re-routing …


Raspberry Pi Cluster For Parallel And Distributed Computing, Ngoc Ha Apr 2019

Raspberry Pi Cluster For Parallel And Distributed Computing, Ngoc Ha

Graduate Theses & Non-Theses

Parallel and distributed computing have become an essential part of the ‘Big Data’ processing and analysis, especially for geophysical applications. The main goal of this project was to build a 4-node distributed computing cluster system using the Raspberry Pi single-board computers for educational and research purposes. After assembling together the system, a standard test was performed to check the system functionality. A Monte Carlo simulation to calculate π (pi) was used to demonstrate the advantages and drawbacks of parallelization and distribution of tasks and data within the cluster. Challenges encountered during installation of the software and testing phase, and their …


The Geology And Geochemistry Of The Golden Chest Gold Deposit, Murray, Idaho, Alexander Brown Apr 2019

The Geology And Geochemistry Of The Golden Chest Gold Deposit, Murray, Idaho, Alexander Brown

Graduate Theses & Non-Theses

The Golden Chest Au-W Mine has been intermittently mined since the 1880’s. Mineralized quartz veins have been deposited into the Upper Prichard Formation of the Proterozoic Belt Supergroup. The Golden Chest is located in the Summit Mining District within the Murray Gold Belt region of the greater Coeur d’Alene (CdA) Mining District. A modern geochemical study of the Golden Chest has never been conducted at the Golden Chest.

This thesis investigates, with the collaboration of New Jersey Mining Company (NJMC), the paragenesis of ore forming minerals, the mineralogy of the deposit and the genesis of the ore forming processes. A …
