11. The Paraná.
E. A. S. Delachaux, "Los problemas geograficos del territorio Argentino" (Rev. Univ. Buenos Aires, 1906, v), includes a study of the floods of the Paraná.
The chief source is the memoir of Repossini, "Memoria sobre el rio Paraná" (Bol. Obras Publicas, vol. vi, 1912, pp. 141-168 and 254-264, vol. vii, 1912, pp. 31-48 and 163-186, and vol. viii, 1913, pp. 33-99). It contains on a reduced scale the map issued by the Ministry of Public Works, which is not available in France. The defect is supplied by the English Admiralty Charts, "Rio de la Plata," 1869 (No. 2544 in the Catalogue of Admiralty Charts), and "River Paraná," parts i, ii, iii, iv, v, and vi of 1905 (Nos. 1982/A and 1982/B).
There is an interesting economic summary in W. S. Barclay, "The River Paraná, an economic survey" (Geogr. Journal, xxxiii, 1909, pp. 1-10).
