River restoration projects in gravel-bed rivers are becoming increasingly sophisticated and complex as river managers and scientists attempt to deliver the goals of catchment-scale ecosystem restoration. With increased sophistication, come the...

In fluvial-estuarine systems, three main physical processes zones can be identified: a) river-dominated; b) tide- dominated; and c) wave-dominated. In the river-dominated zone, water and sediment transport is directed seaward, whilst in the...

System-scale patterns of bed roughness exert a fundamental control on flow resistance, sediment transport and river ecological processes. While field techniques for the measurement of roughness are well established they are often invasive, labor...

Technological advances over the past two decades in remotely-sensed and ground-based topographic surveying technologies have made the rapid acquisition of topographic data in the fluvial environment possible at spatial resolutions and extents...

Advances in topographic survey and terrain modelling have enabled a revolution in the study in the fluvial morphodynamics in the last decade. Prior to the advent of electronic tacheometry in the 1990s, the analysis of channel dynamics was...

The sediments, morphological features and riverflows that define the hydrogeomorphology of natural river channels provide physical habitat diversity that sustains the aquatic biodiversity of river ecosystems. This simple concept underpins the...

A shortage of spawning habitat on dammed and regulated rivers has led to the popularity of gravel augmentation and spawning habitat restoration projects among river managers. Spatial complexity has been cited as an important feature of aquatic...

Existing approaches for performing environmental restoration either involve problem diagnosis and assessment with little implementation or ad hoc construction with little forethought. Environmental assessment is an important aspect of stewardship...

Using repeat ground-based topographic surveys and digital elevation model (DEM) differencing to infer reach-scale sediment budgets has become a popular monitoring tool in fluvial geomorphology. However, few studies have used DEM differencing to...

This report was sub-contracted by the Park City Municipal Corporation (PCMC) to provide recommendations for adoption of a Beaver Management Plan. The primary purpose of this report is to advise the PCMC on how best to manage beaver populations on...

Beaver (Castor canadensis) dam-building activities lead to a cascade of hydrologic, geomorphic and ecological effects that increase stream complexity, which benefits a wide-variety of aquatic and terrestrial species. Depending on biophysical and...

Salinity is a driving force for change in hypersaline community structure. The Great Salt Lake is populated at high salinities by the salt-tolerant brine shrimp (Artemia Franciscana) and brine fly (Ephydra gracilis), and lake management decisions...

Farmington Bay of Great Salt Lake has been studied extensively over the last two decades and observations indicate high levels of both nutrients and the toxic cyanobacteria Nodularia spumigena. During 2012-2013 we measured the physical, chemical,...

Farmington Bay is a hypereutrophic embayment of the Great Salt Lake. Monitoring of brine shrimp (Artemia franciscana Kellogg) populations had indicated that brine shrimp densities in Farmington Bay are only 61% of those in the Great Salt Lake....

The Great Salt Lake lies in a terminal basin, and thus accumulates nutrients and other pollutants produced in its watershed. With the growth of communities in the Wasatch Front, ever-increasing stress is being placed on the lake. Farmington Bay,...

Farmington Bay, is a large (100 mi2; 260 km2) and very shallow (mean depth ~3 ft) embayment at the SE corner of the Great Salt Lake, bordering greater metropolitan Salt Lake City. The embayment is largely enclosed by an automobile causeway so that...

Multiple sediment cores were used to address how metals contamination and eutrophication has changed over the last 200 years in the Great Salt Lake. The cores from Gilbert and Farmington Bay were sectioned in 0.5-cm intervals, and analyzed for...

In September 2012 the Aquatic Ecology Practicum class from Utah State University studied the 51km river continuum of the Little Bear River located in northern Utah (Figure 1). The relatively pristine headwaters of the river begin in the Wasatch...

Natural geography and causeways have divided the Great Salt Lake into four bays with limited, but important connections. Most pollutants from cities in Utah flow into Farmington Bay, and to a lesser extent, into Bear River Bay before entering...
