Estudio preliminar del régimen hidráulico del Puerto de Mazatlán, Sinaloa, México

Abstract

Hydraulic parameters have been estimated in the Harbor of Mazatlan, Sinaloa, Mexico. The calculated values are: The harbor channel resistance to the water flow or impedance, 12.3; the Manning number, 0.09; the Darcy-Weisbach friction factor, 0.20; The discharge, 36 m3/seg; and the tidal prism, 6.32 x 106 m3. O’Brien and Clark’s (1973) method has been applied to obtain the three former parameters and Mehta et al. (1977) techniques has been used to evaluate the latter parameters. Bathymetric charts and tidal elevations and velocities data, obtained at select points of the channel as a function of time, were used. In addition surface currents have been measured at a station network spread over the harbor. Basically the harbor hydrodynamics is governed by the ocean tide. The greater velocities were found in the harbor navigation channel, which confines the water circulation, yielding an one-dimentional flow.
