El Salvador in spite of being a small country, it is frequently affected by natural phenomena as hurricanes, droughts and earthquakes that add to the chain of natural and environmental events, that they have meant in terms of losses and damages, a constant wear of the efforts of development and growth that El Salvador has come realizing.
With the creation of the National Service of Territorial Studies it is tried to contribute to the prevention and reduction of the risk of disaster, for what it is of its competition the relative to the investigation and the studies of the phenomena, processes and dynamics of the nature, the environment and the society, that they have direct and indirect relation with the probability of occurrence of disasters and, therefore of losses and economic, social and environmental damages.

The catchment area of the Lempa river is about 18,246 square kilometers. For modeling purposes the river basin has been divided in 15 segments corresponding to each point of monitoring in real time. These points of monitoring include the four hydro power plants as well as hydrometric gauging stations.
