ORTIZ-VERA, Oswaldo. Hydraulic Similarities among the High Andean Hydrological Systems and Transfer of Hydrometeorological Information. Tecnol. cienc. agua [online]. 2015, vol.6, n.4, pp.25-44. ISSN 2007-2422.

The objective of this work was to determine the laws governing hydraulic similarities among the high Andean hydrological systems. To this end, dimensionless hydrological parameters and physical hydraulic models play an important role. The study finds that the Gravelius index, the convergence ratio and the orographic coefficient are necessary and sufficient conditions to determine hydraulic similarity. The parameters obtained from the dimensionless analysis along with conditions of similarity enable exchanging information among similar hydrological systems. Given the dimensionless morphometry on which this methodology is based, its application can be generalized to hydrological systems in other regions, among regions within countries as well as internationally.

Keywords : Andean hydrological systems; hydraulic similarity; transfer; hydrometeorological information.
