Characterization of hydrologic parameters and processes in shrink-swell clay soils

Creator:

Stewart, Ryan D.

Abstract:

Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...

Development and decommissioning of small dams : analysis of impact and context

Creator:

Kibler, Kelly Maren

Abstract:

Management of small dams may have profound implications for the health and integrity of small rivers and freshwater diversity. Global indicators suggest future growth in the small hydropower sector, particularly in developing countries. As a renewable energy source, it is often presumed that small hydropower entails fewer and less severe...

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...

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)...
