The model QUAL2K represents a river as a series of reaches. These represent stretches of river that have constant hydraulic characteristics (e.g., slope, bottom width, etc.). The reaches are numbered in ascending order starting from the headwater of the river’s main stem. Finally, any model reach can be further divided into a series of equally-spaced elements.
