Project for improving the navigability of the 



River Uruguay 

 between the River Plate and Concordia 



OF H. E. THE 

 MINISTER. 



GENERAL REGIME OF THE RIVER 



As this Commission has finished the survey of the Hi- practicability 

 ver Uruguay between Concordia and Coneepcion del 

 Uruguay and has further made a recognizance of the 

 same between the latter town and its mouth, and though 

 the studies of its regime only exist in outline, as the 

 principal part of it, viz: — the precise levelling — by 

 which the numerous observations of velocities of the cu- 

 rrent, as well as the relative propagation of the hoods 

 and tides can be coordinated with accuracy — has not 

 yet been carried out, the Commission is however in a 

 jDOsition to present to the Superiority the results of the 

 works carried out up to the present moment, which prove 

 the practicability of the proyect of H. E. the Minister as 

 described in the Memory presented to the H. Congress 

 in 1899. 



The observations made at the different gauges, which 

 this Commission has placed in the River Uruguay, not 

 only have coroborated the vague opinion which existed 

 that some tides were felt in the Port of Coneepcion del 

 Uruguay, but have closely shown the importance of the 

 propagation of the tidal wave; not only as to the regu- 

 larity with which they occur, hut also as to their ampli- 

 tude. 



This circumstance — a direct levelling not existing - 

 has made it possible to utilise the tidal observations
