Stability Evaluation of Massive Landslides Using Ensembled Analysis of Time-Series InSAR and Numerical Simulation along the Yellow River, Northwestern of China

Geofluids, 2022
Loess landslides are a major geological disaster in the southeastern Qinghai Province, causing huge economic losses and casualties. The particularity of loess determines the disaster initiation mechanism, disaster mode, genetic mechanism, and complexity ...

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

River Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

River Research and Applications, EarlyView.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Mechanism of Structural Evolution of Limestone of Qinghai–Xizang Plateau Under Coupling Effect of Freeze–Thaw Cycles and Hydrochemical Erosion

Geofluids
The scientific understanding of the evolution of limestone structure under the combined action of freeze–thaw cycles (F-T cycles) and hydrochemical solutions is of great significance for revealing the mechanism of frost damage generation in cold ...

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch (Macquaria ambigua)

River Research and Applications, EarlyView.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch (Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin.

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

River Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

River Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

River Research and Applications, EarlyView.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.
