Effects of an engineered log jam on flow structure and complexity

Creator:

L'Hommedieu, William J.

Abstract:

The installation of engineered log jams (ELJs) is a common river restoration practice, implemented to modify flow structure and increase hydraulic complexity for the benefit of streambank protection and fish habitat. However, few studies have directly assessed the effects of ELJs on flow structure and complexity. This study presents a...

Empirical Analysis of Processes Affecting Drainage Flows and Inversions in a Forested Mountain Landscape

Creator:

Malek, Ali

Abstract:

The objective of this dissertation was to understand the physical mechanisms affecting inversion events in a complex forested mountain landscape. This work was motivated by the long-term studies of climate at the Andrews Forest, short-term studies of vertical temperature, light, wind, and moisture gradient in old-growth trees, and interest in...

A Novel Approach to Process-based River Restoration in Oregon : Practitioners’ Perspectives, and Effects on In-stream Wood

Creator:

Bianco, Stephanie R.

Abstract:

The widespread fragmentation, channelization, and simplification of river ecosystems has had acute environmental impacts, including degradation of water quality and habitat and biodiversity loss (Vörösmarty et al., 2010). These concerns have incited an increased focus on reestablishing ecological and hydrogeomorphological functions and improving habitat that has been lost in riverine...

The historic and contemporary ecology of western Cascade meadows : archeology, vegetation, and macromoth ecology

Creator:

Highland, Steven A.

Abstract:

Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...
