      Fundamentals of Open Channel Flow outlines current theory along with clear and fully solved examples that illustrate the concepts and are geared to a first course in open channel flow. It highlights the practical computational tools students can use to solve problems, such as . Our ability to detect these advantages in contrast to earlier EIS follow-up studies may be due to our longitudinal assessment model that provided periodic assessment over the full five-year study.

Hack's law is an empirical relationship between the length of streams and the area of their L is the length of the longest stream in a basin, and A is the area of the basin, then Hack's law may be written as = for some constant C where the exponent h is slightly less than in most basins.

h varies slightly from region to region and slightly decreases for larger basins (>8, mi² Bedforms: Ait, Antidune, Dune, Current ripple. Longitudinal Elevation Profiles of Rivers: Curve Fitting with Functions Predicted by Theory. Studies of Longitudinal Stream Profiles in Virginia and Maryland.

Recurring (intermittent) streams have water in the channel for at least part of the year.A stream of the first order is a stream which does not have any other recurring or perennial stream feeding into it.

When two first-order streams come together, they form a second-order stream.
