Linking the Remote Sensing of Geodiversity and Traits Relevant to Biodiversity—Part II: Geomorphology, Terrain and Surfaces

open access: yesRemote Sensing, 2020
The status, changes, and disturbances in geomorphological regimes can be regarded as controlling and regulating factors for biodiversity. Therefore, monitoring geomorphology at local, regional, and global scales is not only necessary to conserve ...

GIS Application in Fluvial Geomorphology and Landscape Changes

open access: yes, 2020
The main purpose of this Special Issue of Water is to propose on overview of studies and researches, in which the use of GIS is functional to the representation of fluvial geomorphology and river dynamics, linear erosion processes, erosion rates, ancient

Using Trail Cameras to Monitor Culvert Connectivity in Wadeable Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Anthropogenic barriers in aquatic habitats have led to fragmentation and decreased fish diversity worldwide. Road crossing barriers such as culverts are a significant source of fragmentation and can impede aquatic organism passage (AOP). Many large extent efforts to inventory road crossing barriers and prioritize restoration efforts do not ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Experimental Fluvial Geomorphology

open access: yesEos, Transactions American Geophysical Union, 1988
This book brings together in one volume the results of experimental studies, begun in 1969, of drainage basin evolution and hydrology, river channel and valley morphology and behavior, and alluvial fan morphology and sedimentology. These studies were conducted at the Engineering Research Center of Colorado State University, Fort Collins, by the authors

Flood magnitude-frequency and lithologic control on bedrock river incision in post-orogenic terrain [PDF]

open access: yes, 2006
Mixed bedrock-alluvial rivers - bedrock channels lined with a discontinuous alluvial cover - are key agents in the shaping of mountain belt topography by bedrock fluvial incision.

Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

Fluvial Geomorphology, River Management and Restoration

open access: yes
This Special Issue follows a previous SI titled “Fluvial geomorphology and river management”, published in 2021, which addressed the role of fluvial geomorphology in landscape evolution and the impact produced by human activities on fluvial ...
