Creator:: Kasahara, Tamao
Abstract:: Simulations of stream-subsurface water exchange (hyporheic exchange) using a three-dimensional steady state groundwater flow model and a particle tracking model in unconstrained and constrained reaches of small (2nd-order) and intermediate (5th-order) mountain streams were conducted to estimate the effects of geomorphic features on the extent, volume and residence time of...

Creator:: Sharps, Diana E.
Abstract:: This study was undertaken to evaluate the spatial and temporal characteristics of riparian groundwater tables adjacent to beaver ponds. The research was conducted in two parts; in the first portion a two-dimensional, finite-difference computer model was developed and utilized to simulate groundwater elevations through time in pond-adjacent aquifers. Two types...

Creator:: Zhang, Wenqian
Abstract:: Contamination of ground water by non-aqueous phase liquids (NAPLs) has received increasing attention. The most common approach to numerical modeling of NAPL movement through the unsaturated zone is the use of the finite difference or finite element methods to solve a set of partial differential equations derived from Darcy's law...

Creator:: Healy, Robert Peter
Abstract:: This thesis presents a hydrogeologic study of the Parrett Mountain Region, located approximately 20 miles south of Portland, Oregon. The aim of the study was to investigate the impacts of Columbia River Basalt on the regional groundwater system, to expand our understanding of flow through fractured basalt, to improve management...

Creator:: Scherberg, Jacob N.
Abstract:: The Walla Walla basin lies in an arid region of Eastern Washington and Oregon. A large portion of the area is devoted to agricultural production, relying on irrigation water diverted from the Walla Walla River and underlying aquifers occurring within Quaternary and Mio-pliocene era gravel deposits, as well as a...
