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 ...

In recent years, there has been a lack of empirical work devoted to the explanation of migration patterns into the European Union with the exception of country specific studies. At the same time, migration theories have undergone a considerable renewal, which has led to the development of new variables for explaining migration decisions. Three of them

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
