Descripción: The regime of floods and droughts in the Pantanal wetlands determines the distribution and abundance of the wildlife, vegetation and ecological processes. Cattle ranching and fisheries, the main economic activities in this floodplain, are extremely influenced by and depend on this regime. The aim of this work is to propose a Monitoring and Alert System, denoted SISMONPAN, of floods and droughts in the Pantanal for a better management, conservation and decision making, especially in the case of extreme events. A ten years time series, from 2000 to 2009, of estimated satellite precipitation, river stages and flood mapping derived from MODIS surface reflectance bands processed by the unmixing spectral model was analyzed. The main hydrological compartments and their relationships were defined using previous knowledge in the region as well as correlation statistical models derived from upstream - downstream water fluxes. The power and time lag of the correlations between the water fluxes in the hydrological compartments were determined. These data, flood maps and obtained relationships were organized in a database to be used by the monitoring and alert system for the Pantanal region. The SISMONPAN was developed in PHP language using TerraView and TerraLib libraries in its architecture. The system will be available on the Internet, allowing any stakeholder to simulate possible scenarios of floods and droughts based both on the predetermined upstream-downstream water flux relationships and previous events stored in the database.
