Item Contribución para el conocimiento del escenario de riego mediante el análisis multitemporal de imágenes satelitales del río Cauca en el sector de Villa Paz, municipio de Jamundí(Universidad Santiago de Cali, 2020) Guevara Garcés,Angie Vanessa; Melo Vargas, Andrés FelipeThe Cauca River is characterized by being sinuous and alluvial, which implies a great mobility of its channel; The sinuosity of a channel is the mechanism by which a river adjusts its slope when the valley through which it flows is greater than necessary, during its floods they favor the occurrence of floods of the lands used for socioeconomic activities and established villages that are in the banks of the river causing damage to the territory. (López JD, 2011) A contribution was made to the identification of risk setting, risk analysis and evaluation in the village of Villa Paz, and contributed to the Risk Awareness process that feeds the risk reduction and risk reduction processes. Disaster management, a research work is presented, the general objective of which was to analyze the dynamics of the Cauca River in the village of Villa Paz, Jamundí municipality, through the multitemporal observation of satellite images to identify risk setting. To do this, using current remote sensing techniques incorporated into geographic information systems, thematic maps were created with information from NASA satellite images and aerial photographs from the United States Geological Survey USGS; from sensors such as Modis, Globe and Landsat, obtained through the Google Earth Pro platform, and an analysis of the dynamics of the Cauca River was carried out in different periods of time, measuring the ranges and rates of annual displacement of its banks, and Establishing the movement vectors for the displacement of the riverbed, an analysis was also carried out on the threat of flooding in the study area. The results obtained in this work open very positive perspectives for the application of remote sensing in the orientation of strategies for risk monitoring and in the processes of formulating, executing, monitoring and evaluating risk management
