Kinematics of the Columbia Hills Anticline and the Warwick Strike-Slip Fault, Yakima Fold and Thrust Belt, Washington, USA

Creator:

Woodring, Danielle N.

Abstract:

Discrete fault systems accommodate both N-S contraction and dextral shear in concert with clockwise rotational deformation of the North American plate above the Cascadia Subduction Zone. In Washington, the Yakima Fold and Thrust Belt (YFTB) accommodates N-S contraction as a series of ENE-WSW trending thrust faults and folds. NW-striking, predominantly...

Hydrogeologic field investigation and groundwater flow model of the southern Willamette Valley, Oregon

Creator:

Craner, Jeremy D.

Abstract:

Elevated groundwater nitrate (NO3 -) concentrations in the Southern Willamette Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to declare a Groundwater Management Area (GWMA) in Spring, 2004. To better understand direction of groundwater flow, groundwater age, and nitrate transport pathways of the SWV we developed a steady-state...
