Abstract

Through this scientific paper it will be analyzed the main factors regarding the flooding occurred in Colombian especially during the second semester of 2010 and first semester in 2011. It was used information from different sources, especially with the main institutions in charge of climate changes in Colombia. This assignment will give a vision of how flood managements must be correlated with the Eco systemic procedures and management of resources of water all over the world.

Colombia has had different events in when has been affected by La Niña phenomenon, but the one happened in 2010 is by far the most critical event in history of the country. During this report, it will be necessary to identify the causes and effects of this

The event La Niña 2010- 2011, ranks as the second most critical in 51 years, from the Multivariate ENSO Index (MEI) (Wolter & Timlin, 1993, 1998, 2011)
In the other hand, deforestation, waterproofing, drainage of wetlands and agricultural expansion are factors that increase the risk of flooding, because they contribute to increased runoff into rivers, the deposition of sediment in riverbeds and destabilization of saturated soils, that can generate damming and subsequent torrential floods affecting populations and road infrastructure. Nationally, the estimated annual deforestation rate in the period 2000-2007 was 336,000 ha, placing Colombia in eighth place among the countries with the highest deforestation in the world (D,
