Sandbars along the Colorado River in the Grand Canyon are a fundamental part of the landscape - creating habitat for native plants and animals, providing camping beaches, and supplying sediment needed to protect archaeological resources. The Glen...

Beaver (Castor canadensis) dam-building activities lead to a cascade of aquatic and riparian effects that increase the complexity of streams. As a result, beaver are increasingly being used as a critical component of passive stream and riparian...

High resolution DEMs created from high precision instruments (e.g. total station, LiDaR) have become ubiquitous in the field of fluvial geomorphology. They allow a diverse range of spatially explicit analyses including 2D hydraulic models,...

The incised and degraded habitat of Bridge Creek, tributary to the John Day River in central Oregon, is thought to be limiting the local population of ESA-listed steelhead trout (Oncorhynchus mykiss). Restoration efforts for this watershed are...

We quantified all components of a fluvial sediment budget for a discrete flood on an aggrading gravel bed river. Bed load transport rates were measured at the upstream and downstream ends of a 4 km study area on the Provo River, Utah, during a...

The Logan River and its tributaries in northern Utah sustain a significant population of the imperiled Bonneville cutthroat trout (Oncorhynchus clarki Utah) as well as invasive brown trout (Salmo trutta). In general, the upper reaches of the...

The Yampa River, a tributary to the Green River, is the last undammed major tributary in the upper Colorado River Basin. The Yampa River at Deerlodge is actively braiding in an unconfined park valley setting, just upstream of the confined Yampa...

Glen Canyon Dam has fundamentally changed the source, supply, and caliber of sediment carried by the Colorado River through Glen, Marble, and Grand Canyons. The first survey of the thalweg over the 225 river miles (365 km) within these three...

Availability of Bonneville cutthroat trout (BCT - Oncorhynchus clarki Utah) habitat continues to decline in the Great Basin due to a lack of stream connectivity, over allocation of water resources, and detrimental land use practices. The Logan...

Vegetation plays a fundamental role in controlling channel form and influencing channel processes. Experimental work has shown that stem density, stem spacing, relative submergence, and stem flexibility are key indicators of the effectiveness of...

The high-density of airborne LiDaR and even higher-density of ground-based LiDaR data now facilitates the production of incredibly rich digital elevation and terrain models (DEMs and DTMs), which have transformed how geomorphologists can describe...

Closure of a sediment mass balance - successfully resolving the difference between inputs and outputs with measured changes in storage - is a frequently touted goal of fluvial sediment budgeting, but is rarely achieved. In the rare case when all...

A study of the influences of climate changes in water resource in Salmon River Basin (SRB) is presented. The Salmon River starts in high elevation, mountainous, forest headwaters as an unimpaired river system. Accelerated Climate models for the...

Beavers (Castor canadensis) are frequently referred to as ‘ecosystem engineers’ in part because of the profound influence their dams and associated networks of dens, side-channels and pools have on habitat heterogeneity and the complexity of the...
