Defining stream channels in a watershed is important for assessing freshwater habitat availability, complexity, and quality. However, mapping channels of small tributary streams becomes challenging due to frequent channel change and dense vegetation

The smallest hydrodynamic length scales in two-phase turbulence are located at the interface between phases, or fluids, as a result of two-way coupling phenomena. Typically, these interface-generated scales are several times smaller than the dissipat

One hundred and eight Holstein calves (225 ± 1.1 kg and 187 ± 5.2 d) were used to evaluate the physiological and performance recovery after 14 h transportation or feed restriction. Calves were distributed into 6 pens (2 pens/treatment) according to

Constructed wetlands are a widely adopted technology for the treatment of wastewater in small communities. The understanding of their internal functioning has increased at an unprecedented pace over recent years, in part thanks to the use of mathemat
