Monitoring river restoration using fiber optic temperature measurements in a modeling framework

Creator:: Huff, Julie A.
Abstract:: The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...

Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

Creator:: Hale, Abigail E.
Abstract:: Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

A study of stream temperature using distributed temperature sensing fiber optics technology in Big Boulder Creek, a tributary to the Middle Fork John Day River in eastern Oregon

Creator:: Arik, Aida D.
Abstract:: The Middle Fork John Day Basin in Northeastern Oregon is prime habitat for spring Chinook salmon and Steelhead trout. In 2008, a major tributary supporting rearing habitat, Big Boulder Creek, was restored to its historic mid-valley channel along a 1 km stretch of stream 800 m upstream of the mouth....

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...

Evaluation of stream temperature spatial variation using distributed temperature sensing

Creator:: O'Donnell, Tara
Abstract:: Water temperature in rivers and streams is an important factor for aquatic ecosystem health. Measurement of stream temperature has traditionally been accomplished by point temperature measurements, continuous point temperature loggers, and more recently, airborne remote sensing techniques such as Forward-Looking Infrared Radar (FLIR) or Thermal Infrared Radiometry. While each of...

Make it Rain : A Lagrangian Approach to Investigate Land Surface Controls on Moisture Recycling in the Columbia River Basin

Creator:: Tai, Leah Chung-Mei
Abstract:: Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...

Infiltration and temperature characterization of a wastewater hyporheic discharge system

Creator:: Stewart, Ryan D.
Abstract:: The Clean Water Act imposes Total Maximum Daily Load (TMDL) limits on pollutant concentrations within wastewater effluent; in Oregon, thermal discharge is one of the pollutants subject to regulation. The City of Woodburn, Oregon, funded a series of pilot scale studies to investigate the utility of natural systems to reduce...

A predictive model for time domain reflectometry soil water content and salinity measurements

Creator:: Flugstad, Benjamin A.
Abstract:: Soil water content and water potential are two important parameters in determining the status of water in the soil. Improvement in the ability to measure these parameters by way of increased speed, accuracy, resolution, imaging volume, ease of automation, as well as reduced calibration requirements and reduced soil disturbance would...

Temperature and infiltration characterization of a constructed wetland for wastewater treatment

Creator:: Gregory, Christopher T.
Abstract:: The City of Woodburn, Oregon's Wastewater Treatment Plant (WWTP) has been investigating several natural alternatives for improving effluent quality. Based on its current National Pollution Discharge Elimination System (NPDES) permit, the WWTP will require additional reduction of temperature and ammonia levels in the summer, especially in the critical month of...

Optimizing Placement of Weather Stations: Defining and Testing a Meaningful Objective for Multi-Variable Weather Monitoring Networks

Creator:: Snyder, Amelia M.
Abstract:: As the number of weather stations declines globally, ensuring that meteorological monitoring networks efficiently and effectively monitor weather variables becomes increasingly important. Multi-variable weather sensors are becoming more widely available and make monitoring weather phenomena more economical. However, when seeking an optimal spatial distribution of these stations, choosing an objective...
