Spatial and Temporal Landscape Responses to Progressive Tectonic Forcing along California Fault Systems

Creator:

Manopkawee, Pichawut

Abstract:

Understanding the degree to which topography of erosional landscapes in active mountain belts encode the rates and patterns of active deformation in the upper crust is a primary goal in the field of tectonic geomorphology. In particular, the convolved influence of variations in rock mass quality and the erodibility of...

Dissertation
Geomorphic Evidence for Differential Rock Uplift Across the Southern Cascadia Forearc

Creator:

von Dassow, Wesley

Abstract:

The nature of upper plate deformation along the Cascadia subduction zone (CSZ) is poorly understood. Systematic covariation among topographic relief, geodetically determined uplift rates, decadal to millennial erosion rates, and the frequency of episodic tremor and slip (ETS) along the Cascadia forearc suggest a genetic association between forearc topography and...

Debris flows in glaciated catchments : a case study on Mount Rainier, Washington

Creator:

Legg, Nicholas T.

Abstract:

Debris flows, which occur in mountain settings worldwide, have been particularly damaging in the glaciated basins flanking the stratovolcanoes in the Cascade Range of the northwestern United States. This thesis contains two manuscripts that respectively investigate the (1) initiation processes of debris flows in these glaciated catchments, and (2) debris...

Masters Thesis
Contrasting geomorphic responses to climatic, anthropogenic, and fluvial change across modern to millennial time scales, Clackamas River, Oregon

Creator:

Wampler, Peter J.

Abstract:

Geomorphic change along the lower Clackamas River is occurring at a millennial scale due to climate change; a decadal scale as a result River Mill Dam operation; and at an annual scale since 1996 due to a meander cutoff. Channel response to these three mechanisms is incision. Holocene strath terraces,...

Stream channel response to peak flows in a fifth-order mountain watershed

Creator:

Faustini, John M.

Abstract:

This investigation explored how the magnitude, style, and frequency of channel adjustments vary spatially and over time within a 5th-order mountain watershed. Historical data sets, including repeated cross section surveys spanning up to 20 years at five sites on 2nd to 5th-order channels and streamflow records spanning up to 50...

Dissertation
The role of rock resistance and rock uplift on topographic relief and river longitudinal profiles in the coastal mountains of Oregon and a landscape-scale test for steady-state conditions

Creator:

VanLaningham, Sam J.

Abstract:

Analysis of topographic and river morphometric parameters was conducted using digital elevation models (DEMs) and field observations in order to determine the role of variable rock resistance on topographic relief, to examine how spatially and temporally variable rock uplift rates relate to river morphology, and to address the degree to...

Masters Thesis
Sediment transfer and storage in headwater basins of the Oregon Coast Range : transit times from 14C dated deposits

Creator:

Underwood, Emily F.

Abstract:

In steep headwater basins of the Oregon Coast Range (OCR), debris flows episodically deliver material from low-order tributary basins to larger catchments. Much of this material is stored in valleys and gradually removed by fluvial processes. Quantifying the transfer of material from hillslopes to mainstem channels is essential in understanding...
