AbstractPost‐spawning migrations of sea trout (Salmo truttaL.) in two northern Swedish river systems, Vindelälven and Piteälven, were studied. Telemetry was used to evaluate spawning locations, post‐spawning mortality, overwintering survival/habitat selection/location, partitioned natural mortality from dam passage mortality and overall survival from ...

Abstract Since the early 1980s, a water temperature management program has been in existence on the Nechako River system in central British Columbia, Canada. The program releases water based on anticipated meteorological conditions in an attempt to prevent temperature from exceeding a specified threshold of 20°C downstream during a ...

Regulation of Fluid Flow Behavior in Porous Media Based on Particle Migration
The particle migration phenomenon in porous media exhibits dual effects: it can both impede fluid flow and regulate the flow field. The temporary plugging effect induced by particle migration can delay the formation of preferential flow paths in waterflooding and enhance recovery efficiency.openaire +1 more source
