Title: EVALUATION OF THE INFLUENCE OF CANTAREIRA SYSTEM ON THE PIRACICABA RIVER BASIN USING COMPLEXITY ANALYSIS
Issue Date: 1-Aug-2017
Publisher: Editora UFLA - Universidade Federal de Lavras - UFLA
Description: In this work we apply methods Sample Entropy, Cross-Sample Entropy and Multiscale Sample Entropy to analyze the complexity of stream flow and rainfall temporal series at locations that are close to the water reservoirs of Cantareira System. The Cantareira System was built in 70 ties and 80 ties to export 31 m3s-1 from the basin to the metropolitan region of São Paulo city. Previous studies based on classical statistical analysis of monthly data for the period 1947 a 1991 showed the increasing tendency for rainfall for the whole basin and decreasing tendency for stream flow at locations that are close to the water reservoirs. The objective of this work is to evaluate the influence of Cantareira System on the dynamics of hydrological processes in the Piracicaba river basin by applying the methods of complexity analysis. The results show that after the construction of water reservoirs the complexity of stream flow temporal series was altered, while the precipitation dynamics showed different behavior, indicating the influence of water reservoirs.
