CASTILLO, Robinson  and  ESPITIA, Jeniffer C.. Characterization of risk zones by low flow river rises, for the implementation of an early warning system (SAT) with LoRa and LoRaWAN technology. Inf. tecnol. [online]. 2020, vol.31, n.2, pp.47-54. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642020000200047.

This document presents the design of a community Early Warning System (SAT), focused on small and medium-sized rivers. These small bodies of water, generally in Colombia, are not monitored by the state hydrometereological surveillance entity. However, during the rainy season (March-April and October-November) they have the greatest effects on the communities located around their watersheds. The design of the system is based on the analysis of the behavior of rivers near the area of study (Tobia-Cundinamarca), the performance of hydraulic simulations (Ras-MAPPER and HecRAS®), the determination of areas of constant flooding, and subsequently the possible areas of location of the SAT system, which allow safe times for the evacuation of the population. It is concluded that the proposed methodology for small and medium-sized rivers, as well as the design of the community SAT system can be implemented and adapted to any zone that may be exposed to floods or other types of natural events.

Keywords : early warning; flow analyze; hydraulic simulation; Ras-MAPPER; HecRAS; LoRa, LoRaWAN.
