The influence of geomorphic change on ecohydraulics has traditionally been difficult to quantify. With recent improvements in surveying technology, high‐resolution, repeat and topographic surveys have become a common tool for estimating fluvial sediment budgets and documenting spatial patterns of net erosion and net deposition. Using a case study from a spawning habitat rehabilitation (SHR) project on California's Mokelumne River, some new DEM‐differencing analytical tools and ecohydraulic… 

Coupled geomorphic and habitat response to a flood pulse revealed by remote sensing

Despite a growing consensus on the importance of floods in structuring river ecosystems, predicting the geomorphic and habitat response to specific flood pulses across a range of scales remains

Chinook salmon rearing habitat–discharge relationships change as a result of morphodynamic processes

Relationships between fluvial aquatic habitat availability and discharge are often assumed to remain static when used with hydrologic datasets to analyze changes in habitat availability over time.

Hydrogeomorphic controls on spatial pattern of fish habitat in a mountain stream

Spatial heterogeneity and arrangement of physical habitat strongly influence streamdwelling organisms. A primary objective of this dissertation was to examine how hydrogeomorphic controls – channel

The impact of discharge change on physical instream habitats and its response to river morphology

The impact of climate-induced discharge change on fish habitats, based on 1951–2008 time series, was investigated within the crystalline catchment of the Grosse Mühl River in Northern Austria. A

Modelling approach for interstitial sediment dynamics and reproduction of gravel-spawning fish

The complexity and dynamic nature of ecosystem processes impose high requirements on the approaches, methods and modelling techniques applied to support ecological assessments of rivers. Particularly

The relative contributions of ecology and hydraulics to ecohydraulics

A national meeting of the British Hydrological Society held at Loughborough University (UK) focused on process interactions between lotic organisms, flow and sediment at scales relevant to organisms.

Flood‐driven topographic changes in a gravel‐cobble river over segment, reach, and morphological unit scales

Regulated rivers generally incise below dams that cut off sediment supply, but how that happens and what the consequences are at different spatial scales is poorly understood. Modern topographic



Sediment budget for salmonid spawning habitat rehabilitation in a regulated river

Application of a 2D hydrodynamic model to design of reach‐scale spawning gravel replenishment on the Mokelumne River, California

In‐stream chinook salmon (Oncorhynchus tschawytscha) spawning habitat in California's Central Valley has been degraded by minimal gravel recruitment due to river impoundment and historic gravel

Use of habitat heterogeneity in salmonid spawning habitat rehabilitation design

A shortage of salmonid spawning habitat on dammed and regulated rivers has led to the popularity of spawning habitat rehabilitation projects. Habitat heterogeneity is thought to be an important

Effects of gravel augmentation on macroinvertebrate assemblages in a regulated California River

Enhancement projects within anadromous salmonid rivers of California have increased in recent years. Much of this work is intended as mitigation in regulated streams where salmon and steelhead


ABSTRACT: Magnetically tagged particles were used to investigate the effects of sockeye salmon (Oncorhynchus nerka) and floods on the dispersion of coarse bed material in the Stuart‐Takla region,

Monitoring and modelling morphological change in a braided gravel‐bed river using high resolution GPS‐based survey

Recent research in fluvial geomorphology has emphasized the direct monitoring of channel topography as a useful tool to better understand the interrelationship between river form and process, and in

Reach‐scale sediment transfers: an evaluation of two morphological budgeting approaches

This paper compares two approaches used to derive measures of annual sediment transfers within a 1 km long piedmont reach of the gravel‐bed River Coquet in Northumberland, northern England. The

Spawning habitat rehabilitation ‐I. Conceptual approach and methods

Abstract Altered sediment and flow regimes in regulated rivers limit available spawning habitat for many fishes, especially salmonids. Mitigation efforts include spawning habitat rehabilitation and

Evaluation of a Spawning Habitat Enhancement Site for Chinook Salmon in a Regulated California River

Abstract An evaluation of the effectiveness of a project to enhance spawning habitat for Chinook salmon Oncorhynchus tshawytscha was conducted in the Mokelumne River, a regulated stream in

Use of slope creation for rehabilitating incised, regulated, gravel bed rivers

Gravel‐bedded channels often become incised and degraded below dams. Gravel can be added to the channel to rehabilitate hydrogeomorphic conditions, including those promoting salmon spawning. When
