This topical report describes the work performed to calculate the Probable Maximum Precipitation for any location within the overall Tennessee Valley Authority (TVA) basin and Local Intense Precipitation (LIP) at the BFN, SQN, and WBN sites. The report outlines the process, data, and methods used to analyze storms and develop the PMP values. Results and background data are provided and discussed, along with comparisons to previous PMP work in the region. Relevant background data, input calculation, and reference materials are included in various appendices.
Enclosed is one copy of topical report TVA-NPG-AWA16 and one compact disk containing a portable document format (PDF) version of this letter and the topical report.
There are no regulatory commitments associated with this submittal. Please address any questions regarding this request to Russell Thompson at 423-751-2567.
