The Inter-American Development Bank (IDB) produced this report for the Sustainable Energy for All Americas initiative. A team of experts on Amazon hydrology from the Universidade Federal do Amazonas (UFAM) based in Manaus, Amazonas, Brazil carried out the work. This report analyzes existing hydrological data and other available information in order to determine high level feasibility for the deployment of River Hydrokinetic Energy technology in the Amazon River Basin. The investigation is based on an analysis of the ORE-HYBAM database (www.orehybam.org). Eight sites were chosen from the database and analyzed for velocity (water speed) and discharge data, while also considering existing Acoustic Doppler Current Profiler (ADCP) images. The first part of the report provides an overview of the database and data used, as well as of the performed analysis. The second part (results) describes the analysis via graphs and tables of detailed information about the sites investigated. It includes maps with the geographic distribution of the sites and associated data, Google Earth images from each site with an analysis of the river section, and ADCP images. The annex includes graphs showing the results of discharge and velocity analysis.
