Document Summary
Fluvial refers to anything produced by the action of a river and to organisms that are found in rivers. Dynamics is a branch of physical science that is concerned with moving bodies and the physical factors that affect the motion: force, mass, momentum, and energy. Fluvial dynamics reference to water flow, sediment movement and to bedform features resulting from the interactions of flow and sediment transport in alluvial channels. Physical quantities needed to explain fluvial geomorphic processes. Work the product of the force and the displacement of the body in the direction of the force: units: joule. Energy the ability or capacity to do work. Power rate of doing work: p = w/t. Can be expressed by: malbtc, m = mass, l = length, t = time, and a, b, and c are integers, for dimensionless numbers, a=b=c=0, and the dimensional character is expressed as 1.
