This study analyzes the manner in which the channel of the Rio Grande de Manati, located in north-central Puerto Rico, changes in cross section in both the downstream direction from its source waters to its mouth and at seven individual sites along the river. The basic parameters which were measured include the streams width, depth, velocity, bed material size, and size of drainage area. The kinds of bedrock over which the streams flow and the nature of the river bank materials were noted. These measurements were made to determine what changes occur in individual river reaches as flow conditions vary to resolve how the variables of width, depth, and velocity change in the downstream direction at a given frequency of discharge and to ascertain what is the hydraulic geometry of the Rio Grande de Manati and to see if the concept of dynamic equilibrium is valid in a humid tropical stream basin.
