Stream Restoration for the Spawning of Trout: How to Enhance the Egg to Fry Survival and to Monitor the Spawning Efficiency?

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Today, salmonid management is largely based on river restoration. One of the fundamental elements is the creation of functional spawning sites. Key values of sedimentological characteristics must be defined in terms of granulometry, permeability, and oxygen concentration to ensure the best possible success of the operations.

Fine Sediment Depositional Patterns and Fish Habitat Following Wildfire and Debris Flow

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The 2020 Cameron Peak wildfire burned part of the Poudre River catchment in Colorado, USA. The river flows through a high‐gradient canyon before entering a lower‐gradient transition zone with modified channel morphology and flow regime. Widespread post‐fire erosion introduced fine sediment (< 2 mm) to the river, causing sediment deposition and

Making Waves: The Effects of Whitewater Parks on Fish Passage in Colorado

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Instream structures have fragmented riverine habitats throughout much of the world, including the Western USA. Whitewater parks (WWPs) are relatively new instream structures designed to create hydraulic waves for recreational boating and surfing by constricting flows into a steep chute or drop.
