ARREGUIN-CORTES, Felipe I.; RUBIO-GUTIERREZ, Horacio; DOMINGUEZ-MORA, Ramón  e  LUNA-CRUZ, Faustino de. Analysis of Floods in the Tabasco Plains from 1995-2010. Tecnol. cienc. agua [online]. 2014, vol.5, n.3, pp.05-32. ISSN 2007-2422.

The factors that influence floods in the plains of Tabasco are analyzed, including the lack of adequate land planning, deforestation of the upper basins, and a mistaken idea about decreases in the hydrological regime associated with the construction of large dams in the Grijalva River and climate change. A review of precipitation, runoff, management of dams in the Grijalva River basin and floods was conducted for the period 1995 - 2010. The actions taken to reduce flood risks for the population during that period are presented, including the Comprehensive Flood Control Program and the Tabasco Comprehensive Water Program. The conceptual differences between these are indicated. The objective of the present article is to describe the evolution of approaches to reduce flood disasters in the Tabasco plains, the management of reservoirs and a proposal for land management based on the application of a two-dimensional numerical hydraulic model and a nomogram for prevention of rollovers.
