Evaluación temporal de movimientos en masa asociados a la actividad fluvial del Río Monjas.

Abstract

The city of Quito presents several areas with significant geological hazards related to earthquakes, volcanoes and landslides, which have been studied over the years (Secretaría de Seguridad, MDMQ, 2016; Estacio,J. et al., 2013; D'Ercole et al., 2004; Peltre, P.,1989). However, climatic changes accompanied by disorderly population growth have caused a significant acceleration of morphoclimatic events in the last 50 years in the Monjas River watershed (Espinoza,2022), an extremely important area to analyze due to the large population peak that exists accompanied by a constant advance of urbanizations (Secretaría de Seguridad, MDMQ,2016). In the aforementioned context, the following curricular integration work aims to study the fluviomorphological threat brought by mass landslide phenomena, in order to support adequate risk management in the area. The following work will complement studies previously conducted in the area (Chamba,2022; Espinoza, 2022; Altamirano, 2022; Secretaría de Seguridad, MDMQ,2016) which show the urgency of understanding landslides associated with the fluvial activity of the Monjas River. In this sense, a multitemporal analysis of the area has been carried out to show the relationship between the morphological variation of the river, the occurrence of landslides and the urban growth of the DMQ over the years.
