Integración de la incertidumbre natural temporal y espacial asociada al coeficiente de rugosidad Manning en modelos bidimensionales de inundaciones rápidas Alfonso Mariano Ramos-Cañón Lady Carolina Castro Malaver Nicolás Escobar-Castaneda Ingeniería inundación rápida amenaza por inundación coeficiente de rugosidad Propagación de la incertidumbre Contexto: La variabilidad natural (incertidumbre) espacial y la temporal de los insumos que intervienen en la modelación hidrodinámica, para la evaluación de la amenaza y la delimitación de las zonas potencialmente inundables, se propagan en las variables de salida de los modelos. En la práctica, suele considerarse la variabilidad natural temporal en términos de periodo de retorno, pero poco se ha analizado la propagación de la incertidumbre espacial del coeficiente de rugosidad. Metodología: En este trabajo se presenta el análisis de la propagación de la incertidumbre a través del método primer orden segundo momento del coeficiente de rugosidad de Manning, en las variables de salida de profundidad, velocidad e intensidad de flujo del modelo numérico de aguas someras, implementado en HEC RAS 2D. Se analizó una inundación súbita simulada en el municipio de Mocoa (Putumayo) y la correspondiente probabilidad de alcanzar un nivel de daño para diferentes periodos de retorno, a propósito de los eventos ocurridos en marzo de 2017.Resultados: Se obtiene un procedimiento aplicable a la evaluación de la amenaza de inundación, en el que se integra la variabilidad natural temporal asociada a las hidrógrafas con diferentes periodos de retorno, y la variabilidad natural espacial relacionada con el coeficiente de rugosidad de Manning. Conclusiones: La propagación de la incertidumbre establece una relación directa entre el aumento del caudal (periodos de retorno) y el aumento de la incertidumbre en la evaluación del indicador de amenaza por inundación. 2023 artículo científico 0123-921X https://www.redalyc.org/articulo.oa?id=257077928001 https://www.redalyc.org/journal/2570/257077928001/ https://www.redalyc.org/journal/2570/257077928001/html/ https://www.redalyc.org/journal/2570/257077928001/257077928001.epub https://www.redalyc.org/journal/2570/257077928001/movil https://doi.org/10.14483/22487638.19676 es http://www.redalyc.org/revista.oa?id=2570 Tecnura application/pdf Universidad Distrital Francisco José de Caldas Tecnura (Colombia) Num.77 Vol.27
