Terra Cubes Design Final Technical Report: Design of a Modular Bioretention System for Nitrate, Phosphate and Herbicide Treatment

Creator:: Evans, Lucas, Larson, Lars, Debell, Thomas, and Dunstan, Nicholas
Abstract:: Plant nurseries comprise the largest agricultural sector in Oregon at nearly $1 billion per year. Even at this scale, individual nurseries and greenhouses do not have clear water quality standards set by the EPA. Watershed-level total maximum daily loads (TMDLs) have been set for excess nutrients and herbicides due to...

Introducing the OPEnS HUB 2.0 - A Versatile, In situ, Remote, Sensor Hub

Creator:: DeBell, Thomas C., Goertzen, Luke, Selker, John, and Udell, Chet
Abstract:: Research in geoscience often requires transmission of significant amounts of data from remote locations. The emergence of microcontrollers and open-source sensors are allowing connectivity to affordable, distributed in-situ monitoring. This report describes the OPEnS Hub, a modular data hub orders of magnitude cheaper than commercial dataloggers when scaled to multiple...

Processing 3D Models of Large Instream Wood for Hydraulics Applications – Structure- from-Motion Workflow Documentation

Creator:: Tutka, Michał
Abstract:: Estimating how large instream wood (LW) may impact local hydraulics is critical both for mitigating flood hazards and for ensuring intended habitat benefits of the LW are produced. In practice, the design of forms such as LW is limited by a lack of mechanistic tools for estimating how LW features...

Understanding Aquifer Water Retention Dynamics Using Groundwater Head Relaxation Time

Creator:: Jimmie, Jordan A.
Abstract:: Diking and channelizing in the Toppenish Creek basin, associated with irrigated agricultural development, has altered its natural ecosystem function and hydraulic processes. We seek to answer two research questions: if surface waters are diverted for aquifer recharge in the winter, will this water be available for ecosystem function in the...

Modeling the Influence of Wildfire Management Networks in Social-Ecological Systems

Creator:: Avila, Colton C.
Abstract:: Wildfire management networks allow for collaborative intervention in mitigating the ever-present risk of major wildfire events. This thesis consists of two manuscripts that explore the topology and characteristics of wildfire management networks and their ability to influence wildfire severity in social-ecological systems. The first manuscript focuses on the characteristics of...

A land application treatment strategy for landfill leachate and water reclamation

Creator:: White, Steven G.
Abstract:: The objective of this study is to evaluate the potential of removing organic carbon and inorganic nitrogen contaminants, and metals from the leachate prior to any land application. New guidelines are needed to ensure the environment and our health is not put at risk. The cost of installation, operation and...

Development of a Statistical Emulator of US Crop Yields via a Deep Neural Network Approach

Creator:: Proctor, Kyle W.
Abstract:: Agricultural systems are inherently complex; understanding these systems requires knowledge of climatology, plant physiology, soil physics, economics, and the human psychology of the farmers themselves. Decision support tools strive to leverage existing data to help guide stakeholders towards the best policies and practices for their situation. Quantitative crop simulation models...

Opening Pandora’s Box: Machine learning applications for chemical forensics and non-target chemical analyses

Creator:: Davila-Santiago, Emmanuel
Abstract:: Water bodies act as chemical data loggers that contain tens of thousands of molecules that represent the sum of the biological, chemical, and physical processes occurring within a watershed. We hypothesize that unique chemical signatures present within a water sample can be informative of upstream processes. By extracting non-polar organic...

Enhancing Hydrogen Production using Single Chamber Microbial Electrolysis Cells by Tackling Hydrogen Scavengers

Creator:: Wang, Luguang
Abstract:: Biological hydrogen production from renewable feedstocks was reckoned as a promising method for sustainable energy production. Bioelectrochemical hydrogen production using microbial electrolysis cells (MECs) demonstrated superiorities over the conventional methods for hydrogen production. The introduction of the membrane-less single chamber design further improved the feasibility of MECs for practical application,...
