The influence of woody debris on channel morphology and aquatic habitat has been recognized for many years. Unlike sediment, however, little is known about how wood moves through river systems. We examined some dynamics of wood transport in streams through a series of flume experiments and observed three distinct wood transport regimes: uncongested,(More)
Rivers carved into uplifted plateaus are commonly disrupted by discrete events from the surrounding landscape, such as lava fl ows or large mass movements. These disruptions are independent of slope, basin area, or channel discharge, and can dominate aspects of valley morphology and channel behavior for many kilometers. We document and assess the effects of(More)
[1] Debris flows have typically been viewed as two-phase mixtures of sediment and water, but in forested mountain landscapes, wood can represent a sizable fraction of total flow volume. The effects of this third phase on flow behavior are poorly understood. To evaluate whether wood can have a significant effect on debris flow runout in small mountainous(More)
principle of multiple use management of the Nation's forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research, cooperation with the States and private forest owners, and management of the national forests and national grasslands, it strives—as directed by Congress—to provide increasingly greater(More)
Young basalt terrains offer an exceptional opportunity to study landscape and hydrologic evolution through time, since the age of the landscape itself can be determined by dating lava fl ows. These constructional terrains are also highly permeable, allowing one to examine timescales and process of geomorphic evolution as they relate to the partitioning of(More)

Large ̄oods can have major impacts on riparian forests. Here we examine the variability and spatial distribution of riparian forest responses along eight thirdto ®fth-order streams following a large ̄ood ( 100 year recurrence interval) in the Cascade Mountain Range of Oregon. We categorized disturbance intensity (physical force) exerted on riparian trees(More)

Geomorphic models have a wide range of capabilities in terms of prediction, and this range is part of the reason for this volume. Haff [1996] pointed out that landscape-scale geomorphic models are fundamentally ill-suited to precise prediction and that reductionism is ill-suited to landscapescale problems. Geomorphic models run the gamut of spatial and(More)
