Spatio-Temporal Morphological Changes Of The Cagayan River Section In Tuguegarao City, Philippines

Abstract

Rivers are an essential part of the earth's systems, providing humans with a variety of services. However, natural and
anthropogenic factors have resulted in a global degradation of river health despite our reliance on rivers. Such factors have led to fluvial processes such as floods, channel migration, and riverbank erosion, posing a significant threat to humanity. The controlling factors working at various spatial and time scales within the Cagayan River section in Tuguegarao City will be discussed in this study. In addition, spatio-temporal analysis of the river will be conducted using Remote Sensing and Geographical Information System (GIS) technologies to determine river morphological changes and erosion detection on a long timescale (1985-2020).
