Abstract

The Ucayali River, one of the largest rivers in the Peruvian Amazon, is one of the most dynamic rivers in the region. The Upper Ucayali River is a single-thread, meandering river, while the Lower Ucayali has multiple threads. Before being able to answer complex questions such as if the planform characteristics of Ucayali River are affected by climate change or land use change, the river itself needs to be characterized. The river can be characterized both in terms of the planform and morphometrics. I have developed a toolbox to facilitate the calculation of static planform statistics on meandering rivers, and have calculated some basic parameters of a reach of the Ucayali, including wavelength, amplitude, and orientation of bends. In order to understand the morphodynamic processes on the Lower Ucayali River, which has multiple threads, I have conducted a case study of one reach where two cutoffs have occurred in recent years, and where a third may soon happen. The study includes a temporal analysis using satellite imagery, hydrodynamic and morphodynamic field measurements and a two-dimensional Reynolds Average Navier Stokes (RANS) model, in order to predict how and when the cutoff may occur.
