Abstract
La cuenca del Río Tahuando se encuentra a lo largo de la cordillera oriental de la sierra norte del Ecuador, constituye una zona de influencia socioambiental debido a que sus aguas atraviesan varios asentamientos rurales y urbanos dentro de la provincia de Imbabura, frente a esta problemática, este estudio busca caracterizar la geomorfología y conocer la dinámica de escurrimiento de aguas de la cuenca e identificar zonas de amenaza o riesgo dentro de esta, a través de mapas temáticos haciendo uso de un Sistema de Información Geográfica (ArcGIS 10.7.1). Para el presente estudio se analizaron las propiedades de forma, físicas y de red hídrica de la cuenca hidrográfica, cuyos resultados permitieron conocer sus características geomorfológicas y comprender el funcionamiento de su red de drenaje, como resultado final se obtuvo que el escurrimiento de aguas dentro de la cuenca se produce de forma moderada, siendo así que se trata de una cuenca en equilibrio o fase de madurez lo cual indica un bajo nivel erosivo y sedimentario, con respecto a la amenaza ante riesgos, se observó que, las zonas de mayor grado ante la susceptibilidad de deslizamientos se concentran en mayor magnitud en la cuenca alta, es decir la zona montañosa, mientras que las zonas de mayor grado ante inundaciones se distribuyen en mayor medida entre los principales causes de la red hídrica.
The Tahuando River Basin runs along the eastern range of the northern Sierra region” of Ecuador. It constitutes an area of socio-environmental influence as its waters flow through several rural and urban settlements within the province of Imbabura. In response to this issue, this study aims to characterize the geomorphology and understand the water runoff dynamics of the basin, as well as identify areas of threat or risk within it, using thematic maps generated through Geographic Information System (GIS) technology (ArcGIS 10.7.1). This study analyzed the shape, physical properties, and hydrological network of the watershed, the results of which provided insights into its geomorphological characteristics and the functioning of its drainage network, the final result indicates that water runoff within the basin occurs moderately, suggesting it is a basin in equilibrium or a mature phase, which implies a low erosive and sedimentary potential. Concerning the threat of risks, it was observed that the areas most susceptible to landslides are concentrated primarily in the upper basin, i.e., the mountainous area, while areas with a higher susceptibility to flooding are more widespread within the main channels of the hydrological network.
