摘要

The main objective of this study is to exemplify the use of remote sensing data to evaluate human interference in fluvial systems. River Canas Basin was selected as a test site since it belongs to the Paraiba River basin where human action has disrupted natural equilibrium. Multitemporal aerial photography was analyzed so as to detect changes in fluvial morphology. The rate of environmental change was checked against remote sensing data available by using field work information. Results permitted identification river channel changes over time as well as local factors which explain the variability of change rates.
