The La Salada basin, with an area of 21,362 ha, is subsidiary to the La Picasa basin system. This area was severely affected by floods caused by heavy rains resulting from the Niño event of 1998-99, producing heavy economic losses due to the destruction of crops and pastures, and material damage to infrastructure, such as wire fences and buildings. However, it was observed that the impact of the meteorological phenomenon was not uniform, but that there was a diversity of situations produced by natural and anthropic factors. These factors are what make up the vulnerability of a territory. The general objective of this work is to develop an integrative methodology for risk management in the face of flood hazards, which makes it possible to evaluate and compare the vulnerability of different landscape units and homogeneous areas as a resource for managing the use of the landscape.
